The best private mood tracker apps for iPhone (2026).

Disclosure: we make Luvia, and it is on this list. We put it first because this is our list; the other four entries are real recommendations, and for some readers they are the better pick. We say which readers under each one.

A mood log is one of the most intimate datasets you can produce. It records the bad days, the medication guesses, the names you mention when things are hard. So before comparing features, ask two questions of any tracker: where does this data physically live, and what does the company sell? When the answer to the second is "ads" or "your attention", the first stops mattering. All five apps below pass that bar in different ways.

1. Luvia, for privacy plus warmth

Our own answer to the category. Mood check-ins, an autosaving journal, gratitude and photos all live on your device, never in a feed and never in an ad profile. Around them sit a meditation timer, the WOOP method and sealed notes to your future self, plus the one feature with a heartbeat: Kind Messages, anonymous moderated support between people, one message and one reply. The business model is the privacy policy: a subscription, no free tier, which funds moderation instead of advertising. Skip it if you want free, Android, or gamified streaks.

2. Apple Health's State of Mind, for zero commitment

Since iOS 17, mood logging is built into the Health app: momentary emotions, daily moods, and correlations with sleep and exercise, protected by Apple's health-data encryption. It costs nothing, requires no new app, and its privacy posture is excellent. It is also the most minimal option here, with no journal to speak of and all the warmth of a settings screen. Start here if you are not sure tracking is for you at all; Luvia is where you graduate when you want warmth, real writing and kindness on top of the same on-device privacy.

3. How We Feel, for learning the vocabulary

A free app built with academic input on emotion science, organised around naming feelings precisely rather than just rating them. Its check-ins teach an emotional vocabulary that genuinely transfers to life off the phone. Journalling depth is limited and there is no community, but as a free, well-intentioned teaching tool it is easy to recommend, especially for younger users starting out. Luvia adds what it leaves out: a private journal, rituals, and a place for the feelings once you can name them.

4. Daylio, for the longest streak

The fastest logger in the category: two taps, widgets, streaks, and satisfying long-run statistics. Data can be kept local with manual backups, and a generous free tier makes it the easiest trial. It optimises for consistency rather than reflection, which is either its flaw or its genius depending on you; Luvia makes the opposite bet, that a minute of honest writing beats an unbroken streak. We compared it with Luvia in more depth here.

5. Bearable, for health correlations

The right choice when mood is one variable in a bigger health investigation: symptoms, medication, sleep and custom factors, with correlation reports built for doctor's appointments. It is denser and more clinical than anything else on this list, deliberately so. Pick it for detective work; pick Luvia when what you need from the same five minutes is calm.

How to choose

If you want zero friction and zero cost, start with Apple's built-in State of Mind and see whether the habit sticks. If it does and you find yourself wanting somewhere warmer to write, with the day's mess kept on your own device and a little anonymous kindness attached, that is the gap Luvia was built for. And if your tracking is really health research in disguise, go straight to Bearable and take notes for your doctor.
