Mosaik - A calm habit tracker where your habits paint a picture
by•
Mosaik is a calm habit tracker for iPhone where your habits paint a picture. Every day you show up adds a piece of sea glass to a 66-day canvas that slowly reveals a hidden picture. A missed day is a quieter piece, never a reset.
It follows the sun: sky by day, deep blue with the moon at night. Breaks and easy days, goals, Apple Health auto-tracking, widgets and an Apple Watch app.
Free for 3 habits, no account needed. iPhone only for now; Android is coming soon.

Hi Product Hunt 👋 I'm Kresimir, an indie developer from Croatia, and this is the first time I'm sharing Mosaik here.
I kept quitting habit trackers the day I broke a streak. A red X after 40 good days felt like losing all of them. So I built Mosaik around one rule: a missed day is just a quieter piece of the picture, never a reset.
Why 66 days? In a 2010 UCL study, new habits took a median of 66 days to feel automatic, and missing a single day didn't undo the progress.
What's in it: a 66-day sea-glass canvas with a hidden picture, a day arc that follows the sun, breaks and easy days, reminders that stack habits, widgets, Siri and an Apple Watch app. Free for up to 3 habits, with no account needed.
It's iPhone-only for now (Android is coming). I'd love to hear what would make it more useful for you.
