I know the feeling – but not its name.

MoodCards

You don't need a diagnosis to understand your emotions better. 111 emotions – many of which you've never named. Each has a profile: where does it come from, what triggers it?

111 emotions with profile — origin, function, related feelings
MoodCards — discover patterns you can't see yourself, without diagnosis, without judgement
Plutchik model explained clearly — dyads, emotion chains, evolutionary functions

You already track a lot – but what really moves you? Emotional patterns only emerge when you name them. The data accumulates along the way, the patterns appear by themselves.

Trend chart — emotional patterns visible over weeks and months
MoodCards — randomly selected, showing what you overlook day to day
111 named emotions — once you know them, you see them in yourself

Plutchik, dyads, emotion chains – you know the theory from therapy. Here you encounter it through your own emotions, not in a textbook.

Plutchik dyads and emotion chains — traceable through your own feelings
Emotion profile — counter-emotion, triggers, what the feeling wants right now

When you first open the app, five common emotions are already saved as favourites. No setup, no searching – you can start immediately. And you can customise the selection at any time.

Tap the zap icon

The ⚡ in the footer opens Fast Track directly – from anywhere.

Choose intensity

For each favourite emotion: how strong is it right now? Or skip.

Done

Brief summary, matching skills – and you can carry on.

5 taps. That's it.

With three favourites your daily check-in takes under half a minute – even when things aren't going well.

Built for difficult moments.

Fast Track is not optimised for good days. It works precisely when energy and focus are in short supply.

Routine, not effort.

The shorter the entry takes, the more likely it actually happens – every day, not just when you feel like it.



More than tracking — everything that matters long-term.

Skills, patterns, analytics, AI insights. Strong individually, a system together.

No searching when things get hard – your kit is already packed.

Decide now, calmly, what helps – so you don't have to decide anything in a crisis.

The skill system at a glance

This is the DBT principle behind the skill system: you build your emergency plan in a calm moment. When it counts, you only need one tap.

  • Skill library – 167 immediately available skills – plus 695 additional DBT+ skills (Pro) available as an add-on
  • Skill matrix – 4 tension levels × 3 availability tiers – at a glance which skill fits when
  • Scenarios – up to 3 personal contexts (e.g. "At home", "Out") – each with its own matrix
  • Skill chains – sequences for situations where one skill alone isn't enough
  • Custom skills – create your own by text or audio – or permanently hide existing ones
  • Hide – permanently deactivate skills that trigger you or you never use

Skill library

You open the library – and immediately see what's available. No setup, no searching. 167 skills from all DBT modules, ready to use.

  • 167 standard skills immediately available – no setup needed
  • DBT+ (Pro): 695 additional skills – available as an add-on
  • Skill matrix: 4 tension levels × 3 availability tiers
  • Usage counter shows which skills you actually use

Skill matrix

In the moment of crisis you already know what works – because you decided in advance. The matrix is your personal emergency plan: 4 tension levels, 3 availability tiers, filled by you.

  • Tension levels: low / medium / high / extreme
  • Availability: always / easy / demanding
  • In a crisis: filter to your current tension – only matching skills visible
  • A separate matrix configurable per scenario

You prepared. That's the difference.

Scenarios

You're a different person at home than out and about. Scenarios take that seriously: each context gets its own plan – built in advance, instantly accessible in a crisis.

  • Up to 3 scenarios (e.g. "At home", "Out", "Work")
  • Each scenario has its own skill matrix with its own skill kit
  • In a crisis: one tap on the scenario, filter by tension – no searching
  • Switch quickly depending on context

No thinking when things are hard. You've already done that.

Skill chains

Sometimes one skill isn't enough – some situations need a sequence. Chains link multiple skills in the order that helps you: as a crisis protocol, a morning routine, an evening ritual.

  • Combine any skills in any order
  • Start a chain → guided step by step
  • Usage counter: see what you actually use
  • Great for morning routines, evening rituals, crisis protocols

Integrated tools

Some techniques need more than a text. These tools run directly in the app – with animation, timer or guided flow. No leaving the app, no external searching.

  • Breathing exercise with visual animation and adjustable rhythm
  • 5-4-3-2-1 grounding guide
  • Body scan and progressive muscle relaxation (PMR)
  • Tools are embedded directly in the skill library

Custom skills & personalise

A library that fits you gets used. One that doesn't, gathers dust. Create custom skills, hide triggering ones – until only what really helps remains.

  • Create custom skills by text and add them to the matrix
  • Audio skills: attach your own MP3 or external URL
  • Permanently hide skills that trigger you or you never use
  • Always reversible – no skill is ever deleted
Skill matrix

Skill matrix · skill kit

What moves you – before your mind starts to explain.

22 cards, no prior knowledge needed – you see your emotional profile without having known what you were being asked.

MoodCards at a glance

You know the feeling: you ask yourself how you are – and give the answer you expected anyway. MoodCards bypasses this. You rate a card before you know which emotion it shows. The result: an emotional profile without self-censorship.

  • Assessment – rate the card before the name appears – projective method without self-censorship
  • Reveal – the emotion is only disclosed after the rating
  • Dashboard – weighted emotional profile from ~35 cards
  • AI interpretation – baseline mood analysis from 200 ratings
  • History – how your profile changes over weeks

Assessment

The question "How are you?" has a catch: you already know your own answer before you ask it. MoodCards asks differently. One card, one description – you rate how frequent, how intense, how current. You only see the name afterwards.

  • 3 dimensions: frequency, intensity, recency
  • Random order – no systematic prior assumptions
  • Short and focused: one card, three sliders
  • Covers all 111 emotions from the Plutchik model

Reveal & feedback

Sometimes the reveal confirms what you suspected. Sometimes it surprises you. Both are information – and only possible because you rated before you knew what you were rating.

  • Name and description of the emotion are revealed
  • Your values in context of your previous ratings
  • Direct access to the emotion profile
  • Immediate feedback: is your intuition close or far off?

* The card shows a description – not the name. You rate what you feel before you know what it's called. No prettifying, no averaged picture of yourself.

Dashboard & analytics

After ~35 cards a pattern emerges that you haven't talked yourself into. The dashboard shows which emotions systematically dominate your life – weighted by frequency, intensity and recency.

  • Weighted profile: frequency × intensity × recency
  • Horizontal bars with median and spread range
  • Which primary emotions dominate – which barely appear
  • PDF export for the therapy session – generated locally

AI interpretation

From 200 ratings the AI interprets your profile. No generic text – an interpretation of your own data. What shows up systematically? What surprises you? Conversation basis for your next therapy session.

  • Which emotions are systematically dominant
  • Patterns over time – what repeats
  • Tone selectable: casual or clinical
  • Your own API key – data goes directly to your provider
MoodCards

MoodCards

Why you react the way you do – and what it does to you.

You don't need to memorise it – the app applies it when it counts.

Emotion playbook

You react to something – and afterwards don't quite know why. Each of the 111 emotions has its own profile: where it comes from, how it escalates, what it does to you. Not as a reference – as a mirror.

  • Where the emotion comes from – triggers, body signals, biological function
  • Escalation chain: what happens if you don't intervene
  • Related emotions visible – so you recognise the right one
  • Direct skill recommendations for exactly this emotion

Scale playbook

Between numbness and emergency lie ten levels. Knowing where you are right now – not just "bad" or "very bad" – is the difference between preventing and escalating.

  • 10-level tension scale following DBT: numbness → emergency
  • Colour coding: see immediately which range you're in
  • Each zone needs different skills – the playbook shows which
  • Scale value directly linked to the skill matrix filter

Emotion model

Why does anger sometimes feel like fear? Why does relief sometimes follow long sadness? Marcus'Mood explains what's behind it – based on the Plutchik wheel, one of the strongest models in emotion psychology.

  • 8 primary emotions + 2 DBT states – and how they connect
  • Mixed emotions (dyads): why joy + fear = excitement
  • Yerkes-Dodson: why moderate tension makes you more productive
  • References – evidenced models, not claims

How skill matching works

Other apps show you a list. Marcus'Mood selects – based on what you're feeling right now, how strong it is, what you can do and where you are. That's the difference between eighty suggestions and one that fits.

  • Emotion · intensity · availability · context – four dimensions simultaneously
  • Crisis, activation, vulnerability – the right context per situation
  • PLEASE factors feed in: sleep, nutrition, substances
  • Rizvi et al. (APA): 68% distress reduction per app session
Emotion playbook

Patterns you would never have seen on your own.

Sometimes you only see after weeks what regularly happens. The analytics makes visible what you can't track on your own.

Trend curve

You choose an emotion – the app shows you how it has developed over weeks. Whether it's actually getting worse, or just feels that way.

  • Intensity history of individual emotions over weeks
  • 14-day smoothing: trends instead of daily fluctuations
  • Multiple emotions comparable simultaneously
  • Weekday patterns: when you're regularly higher

Calendar

Which days of the week are regularly hard? Are there months when you're more stable? The calendar makes time rhythms visible that you don't notice in daily life.

  • Heatmap: 13 weeks – intensity at a glance
  • Monthly view with intensity dots per day
  • Day detail: all entries for a day
  • AI assessment of baseline tension

Five findings from independent clinical research on DBT apps – different studies, different populations, the same conclusion: most apps don't solve the problem. Marcus'Mood is deliberately built differently in each of these areas.

When you open a skill in a difficult moment, the odds are in your favour. That's not coincidence – that's DBT, applied.

68% of sessions with skill use led to a measurable decrease in distress.
In pilot studies of DBT Coach with patients with emotion dysregulation and borderline personality disorder, 68% of app sessions resulted in a measurable decrease in acute distress – 30% also showed fewer self-harm urges. Rizvi et al., 2011 & 2016 · APA Journal of Consulting and Clinical Psychology

Fast Track is not a convenience feature. It is the clinically grounded, necessary answer to the biggest problem with DBT apps.

48% dropout rate in a controlled study with 576 participants.
In the RCT Resilience eDBT (n=576), over 80% started the app – fewer than half stayed. Dropout rate: 48%. Main cause: too many steps, too much effort, gave up too early. Anderson et al., 2024 · NIH / PubMed (n=576)

61% of therapists had to ask patients to hold their phone up to a webcam.

When you actively support clients using Marcus'Mood, they are significantly more likely to stick with it – that's not coincidence, it's evidenced.

Therapist-assisted apps have 30–40% lower dropout rates than self-directed ones.
A systematic review of digital DBT interventions shows: when therapists actively support app use – even without direct data access – the dropout rate drops by 30–40% compared to self-directed use. The recommendation works. Active support works more. Systematic Review · Journal of Medical Internet Research (JMIR)

The studies cited were not conducted on Marcus'Mood and refer to other DBT apps under study conditions. They evidence general effectiveness principles of DBT app use, on the basis of which Marcus'Mood was developed.

111 emotions based on one of the most cited emotion models

Robert Plutchik identified 8 primary emotions with evolutionary functions (fear = protection, anger = destruction, joy = reproduction…). Dyads and triads describe how emotions combine. Marcus'Mood maps this model completely – 111 entries instead of the usual 6–20. Source: Plutchik, R. (1980). Emotion: A Psychoevolutionary Synthesis. Harper & Row.

Skills from Dialectical Behaviour Therapy

Marsha Linehan originally developed DBT for intense, hard-to-regulate emotions. The four modules – Mindfulness, Distress Tolerance, Emotion Regulation, Interpersonal Effectiveness – structure all skills in Marcus'Mood. The 4-factor matching follows clinical logic: emotion, intensity, reactive status and vulnerability determine which skills appear. Source: Linehan, M. M. (1993). Cognitive-Behavioral Treatment of Borderline Personality Disorder. Guilford Press.

Biological factors that influence emotional resilience

PLEASE stands for: PhysicaLillness, Eating, Alter substances, Sleep, Exercise. These six factors influence how we experience and regulate emotions – regardless of the situation. Marcus'Mood makes this connection visible: the PLEASE score feeds into skill matching and correlates with emotion intensity in the review. Source: Linehan, M. M. (1993). DBT Skills Training Manual. Guilford Press.

No account. No cloud.
No compromise.

NIH study: 61% of therapists had to ask patients to hold their phone up to a webcam – because no local file transfer was possible.

Your data never leaves your device.

Moods, crises, patterns – these are among the most sensitive data you will ever record. They never leave your device. No account, no tracking, no cloud. The optional AI analysis is the only exception – and only active when you consciously enable it.

Everything stays local

Your tracking data, skills and MoodCards never leave your device. No server receives them, no cloud service stores them. The only place your data exists is your smartphone – encrypted with AES-256-GCM.

Not collecting data means not having to protect it

We collect no personal data – which means we have nothing to protect, nothing to delete, and nothing that could leak in a breach. This is the most consistent form of privacy: not collecting rather than protecting.

No account required

No email address, no password, no registration – you start immediately. No forced sign-up after the first launch. No "Forced Email" like other mental health apps.

Full control

Export, deletion, backup – all in your hands. You can export all data as JSON, encrypt it, and restore it on another device. Nothing happens without your explicit action.

AI analysis – only when you want it

The optional AI analysis does send data externally – but only when you choose to. Requirement: your own API key, entered in settings. Data goes directly to your chosen provider – not to us. Without a key, everything runs fully offline.

Settings: all data remains on device.

Frequently asked questions

What is "4D skill matching" – and how does it work?

Most apps suggest skills along a single axis: "Bad mood → here's a breathing exercise." That doesn't go far enough. Marcus'Mood combines four pieces of information:

1. Emotion – What exactly is the feeling? (111 entries following Plutchik + DBT, not 5 emojis)
2. Intensity – How strong is it right now? (0–100%, in 10 levels)
3. Reactivity – Is this a first reaction to a situation – or a feeling about a feeling? (e.g. shame about feeling afraid). For reactive emotions, self-compassion and Radical Acceptance are needed first, not a breathing exercise.
4. Vulnerability (PLEASE) – How biologically vulnerable are you right now? Sleep, nutrition, substances, movement and baseline mood influence which skills are realistically applicable.

From the combination of these four factors, a matched skill list is calculated for each emotion – no generic recommendations, but context-sensitive matching following DBT logic.

What does Marcus'Mood cost?

The app is free – permanently, no expiry date, no hidden limits. A Pro version with extended features (PDF export, AI analysis, DBT+ skills, binaural beats and more) is in development and will be available as a one-time purchase. No subscription, no automatic renewal. The price will be announced on release.

What is Fast Track – and how does the ⚡ symbol work?

The ⚡ symbol in the app footer opens Fast Track. With it you check in several favourite emotions one after another – you only choose the intensity, everything else runs automatically. On first launch, five common emotions are already saved as favourites, which you can adjust at any time. Result: a complete tracking entry in under 30 seconds.

What is the difference between the free version and Pro?

The free version is fully featured – mood tracking, 167 DBT skills, Fast Track, calendar, MoodCards, history, tools. No artificial ceiling. The Pro version (in development) extends the offering with 695 additional DBT+ skills, AI voice analysis, PDF export for therapy sessions, binaural beats and more. Pro will be available as a one-time purchase.

What happens to my data?

All tracking data stays locally on your device. We collect none, store none, see none. The only exception is the optional AI analysis (Pro): it sends data only when you activate it with your own API key – and even then only to the service you choose, not to us.

Does the app work without internet?

Completely. Tracking, skills, MoodCards, review, tools – everything runs offline. An internet connection is only needed if you optionally use the AI analysis with your own API key. Everything else works without a connection.

Do I need to know DBT to use the app?

No. The app explains all concepts – Plutchik, DBT modules, PLEASE – step by step. No prior knowledge needed. If you already have DBT knowledge, the app offers significantly more depth: specific skill assignments, structured tracking for therapy sessions and the complete DBT+ skill catalogue.

Does Marcus'Mood replace therapy?

No – and that's a good thing. The app accompanies therapy, it doesn't replace it. It helps with applying skills between sessions, making patterns visible, and going into the next appointment with structure. In acute crises: please contact a crisis helpline in your country.

What is the difference from Daylio or other mood trackers?

Daylio is a mood diary – it tracks moods but doesn't suggest skills. Marcus'Mood does both: name an emotion and then suggest concrete DBT skills that fit this emotion, this intensity and this moment. Also: 111 emotions instead of 5–20 emojis, 100% local, no subscription.

Why this app exists

I know that moment: you're stuck in something difficult and just want to know what could help right now. But nothing is at hand that simply works. Offline, without three steps first.

Maybe you know the feeling too. That's where this app came from – not as a product, but as an answer to a very specific situation.

What it became is more than originally planned. But the core principle stayed: simple enough for difficult moments. Deep enough to actually help.

No corporation behind it. No subscription pressure. Just someone who had the same problem – and decided to solve it.

Your next step begins with a feeling.

Just start. Your emotions, your skills, your path – no account, no cloud, no subscription.

Marcus'Mood is not a diagnostic tool – it supports you in understanding yourself better. · Privacy Policy
