Most free habit trackers cap you at a handful of habits, then gate everything else behind that same wall. Hit the limit and suddenly your mood log needs a card on file too. HabitSync doesn't work that way.
What's actually free
Weight, calories, sleep, mood, and medication are never capped, no matter how many habits you've named. No card, no expiry, no trial clock running out.
Weight, calories, sleep, mood, medication, and daily notes
Every preset habit, plus three you name yourself
Yes/no, numeric goals, and percentage targets
Streaks, adherence, and your 7 and 30 day averages
Your strongest pattern, found in your own data
Join any group with a code
Missed-habit reminders and the Sunday recap email
Export everything to CSV, any time
Yeah, there's a paid plan
I'll say the quiet part: I hope to make some money on this. Gemini calls and hosting cost real money every month, and a free-forever-everything app isn't a business, it's a countdown. What's behind the paywall is the stuff that actually costs me something to run, plus the analysis that took the longest to get right.
