InnerPulse vs Daylio: Clinical Companion or Casual Rating

Daylio's core strength: low friction

Daylio's genius is that it makes mood tracking feel like nothing. You open the app, tap an emoji, maybe pick a few activities, done in under ten seconds. No setup, no learning curve. You can track your mood for a year and never read a single chart.

That low friction is why Daylio has 20 million downloads and roughly 3-5 million USD in annual revenue. If you have never tracked your mood before and you're not sure whether you'll stick with it, Daylio is the correct first step. It asks almost nothing of you.

InnerPulse's core strength: signal you can bring to therapy

InnerPulse asks slightly more of you. Instead of "tap an emoji," you get a 1-10 mood score and five sub-dimensions (energy, calm, focus, sleep quality, social energy). That takes maybe 15 seconds instead of 5. In exchange, you get data that actually tells you - and your therapist - something:

• The correlation engine looks at 85+ influence factors (sleep hours, exercise, caffeine, social interactions, weather, work hours, medication, etc.) and tells you which ones most predict your mood. Daylio has activities but no correlation analysis.
• The clinical screenings (PHQ-9 for depression, GAD-7 for anxiety, K10 for general distress, PHQ-4 for rapid checks) produce scores that map directly to clinical diagnostic criteria. Daylio produces mood emojis.
• The CSV export is something you can hand your GP or psychiatrist at a follow-up. Daylio produces a prettier but clinically meaningless chart.

The "when does it matter" test

Daylio matters when:

• You want to build a habit of reflection without commitment.
• You're curious if your mood is seasonal, weekly, or tied to specific activities.
• You want a private, pretty journal that feels like a game.
• You're not dealing with anything acute - no depression diagnosis, no medication changes, no burnout worries.

InnerPulse matters when:

• You've been diagnosed with depression, anxiety, PMDD, bipolar, or burnout - or suspect one of those - and want to track symptoms the way your doctor does.
• You're currently waiting for a therapy slot (in Germany, the average wait is 142 days). InnerPulse gives your waiting time structure and produces evidence for the first session.
• You started or stopped a psychiatric medication and want objective data on whether it's working.
• You suspect a pattern (PMDD, seasonal affective, burnout) and want to see it in actual numbers.
• You care about data privacy enough that "nothing leaves my phone" matters.

The subscription question

Daylio is free with a Premium upgrade (~€20/year) that unlocks more moods, more goals, CSV export, and themes.

InnerPulse is €4.99 one-time for the entire app. Over three years of use, InnerPulse costs about 8% of what Daylio Premium does.

That said: Daylio's free tier is generous. If you use Daylio casually and don't need Premium, Daylio is effectively free. InnerPulse has no free tier.

Streaks: the hidden reason Daylio fails some users

Daylio gamifies consistency with streaks. For most users, that's fine - the streak is a motivation to log daily. But for users who track mood because they're struggling, streaks can actively harm. Miss a day during a bad week, lose a 47-day streak, and what was meant to help now feels like another failure.

InnerPulse deliberately has no streak counter. The product principle is "emotionally light to open, even on bad days." A tool meant to support you through depression cannot also be a pressure system. This is one of the subtler differences between a casual mood app and a therapy companion.

Data privacy: a real difference

Daylio offers cloud backup tied to a Google account. The data is encrypted at rest, but it's still on a server. That's a trade-off many people accept for the convenience of getting their data back if they switch phones.

InnerPulse has no cloud of its own, no account, no built-in backup service. Your data lives on one device. The one caveat: if you have iOS iCloud Backup enabled, the InnerPulse database is part of that device-wide backup (you can exclude the app in iOS Settings). The upside: no third-party server, no account to recover passwords for. The downside: without iCloud Backup or a CSV export, losing your phone means losing the data.

Mood data is sensitive. For some people - especially those tracking medication use, substance use, or clinically relevant symptoms - local-only is the right answer. For others, cloud backup is worth it.

What about depth of features?

Daylio is wider than it is deep. It has lots of customizable moods, activities, goals, streaks, and themes. It's very configurable in a surface-level way. A 2020 academic audit of mental health apps (Hussain et al., JMIR Mental Health) flagged Daylio's UX as visibly dated, with unclear icons and inconsistent iOS/Android design.

InnerPulse is deeper than it is wide. It has one mood-rating system (the 1-10 plus dimensions), one set of clinical screenings, and one correlation engine - but each of those is built to actually work, not just to give you another button to press.

If you like configuring things, Daylio feels more fun. If you like when tools actually surface insights you couldn't see yourself, InnerPulse feels more useful.

Where they agree

Both apps:

• Let you log daily mood in seconds.
• Store your data privately (with different trade-offs).
• Work offline.
• Don't sell your data.

What about Bearable and Apple Health State of Mind?

Bearable sits between Daylio and InnerPulse: broader custom symptom tracking than InnerPulse, more serious than Daylio. See InnerPulse vs Bearable for that comparison.

Apple Health's State of Mind is the new default on every iPhone - free, built-in, apple-trusted. It's a point-in-time risk screener with three instruments (State of Mind, Depression Risk, Anxiety Risk), not a longitudinal correlation tool. InnerPulse vs Apple Health State of Mind covers that.

The honest answer

If you've never tracked your mood before and you're not sure you'll keep at it: start with Daylio. It's free, fast, and you'll know within two weeks whether mood tracking is something you want in your life.

If you've been dealing with depression, anxiety, PMDD, medication changes, or burnout - or if you already tried a casual mood tracker and wanted something you could actually bring to a therapist: get InnerPulse. €4.99 once, built for exactly this use case, and you'll know within a week whether the clinical-screening approach works for how your mind works.
