Most mood apps hand you a diary with a color scheme. HabitSync asks for one number a day, then lines it up against your habits, sleep, and medications on the same calendar, so a bad stretch has something to be compared against.
The check-in is a 1 to 10 rating, Low at one end and Great at the other, and it takes a tap. Under it sits an optional emotion, picked from a grid of 25 that runs from Furious and Stressed through Content out to Serene. Skip that part on a bad day and the rating alone is still a complete entry. One entry per day, and editing a day replaces it rather than stacking a second one.
Every habit, your sleep, your calorie target, and each medication gets tested against your mood: the days it happened versus the days it didn't. Nothing surfaces until there are enough days on both sides and the gap survives a significance test and a correction for how many things were checked, because scanning a dozen factors against one number manufactures coincidences on its own.
A mood app and a separate habit app cannot answer the question that matters, because nothing joins the two records by date. HabitSync keeps them on one calendar.
Yes, for the tracking. The daily rating, the emotion grid, the trend line, and the export are all on the free plan, with no card and no expiry. The paid plan adds the full comparison of your mood against everything else you log. Free still shows you the single strongest pattern it finds.
A journal stores how the day went in your own words. A tracker turns it into a number often enough that the number becomes comparable. HabitSync does the second and leaves room for the first: the rating is required, the emotion is optional, and a day note sits under both for anything a number can't hold.
It can tell you what lines up with it, which is not the same as what causes it. Each habit, your sleep, and each medication gets compared across the days it happened and the days it didn't, with the sample size shown and weak findings held back. Which way the arrow points is yours to test.
No. It's a self-observation tool. It doesn't screen, doesn't diagnose, and isn't therapy or a stand-in for it. If your mood is the thing you're worried about, the useful move is bringing a record to someone qualified to read it, and this makes a tidy one.
Yes. HabitSync is on Google Play, and the same account works in the browser on any device, so a check-in from your phone and a look at the trend on a laptop are the same record.
