HabitSync

Most habit trackers hand you a wall of numbers and leave you to work out what they mean. HabitSync is built around the part that comes after.
Log your habits, medications, weight, sleep, mood, and meals in one place. The app looks for connections across them and tells you what it finds. Whether your sleep tracks with your mood. Whether a medication lines up with a change in weight. Whether the habit you've kept for three weeks is doing anything at all.

What you can track:
- Habits, from a library of presets or ones you name yourself
- Medications and doses, including as-needed
- Weight, with a forecast built from your own logged numbers rather than a generic formula
- Sleep, mood, and daily notes
- Meals and calories, with photos if you want them

Groups let you share progress with a few people without handing over your daily logs. Nothing is shared automatically. You pick which summaries other members see, and you can turn any of them off whenever you want.
One thing this isn't. HabitSync is not a medical device and doesn't diagnose or treat anything. It shows you patterns in the data you enter. What you do with them is between you and your doctor.
Your data stays yours. Export it whenever you want. Delete your account and everything in it from inside the app, in one step, with no waiting period and no email to send.
