Which Intermittent Fasting App Do Reddit Users Say Is Free And Good?

The recurring Reddit complaint about intermittent fasting apps is that every useful feature sits behind a subscription. FastSyncer's timer, daily check-in, streak, analytics and whole community are free, and the community is built into the app rather than sitting in a separate tab somewhere else.

The complaint behind every one of those threads

The daily parts are not behind a subscription. Timer, check-in, streak, analytics and community: free.
Your streak is the pressure. Days in a row are counted, and a gap shows — that is what makes you open the app.
You can see the month at once. Each day you log fills in, so progress stops being a feeling.
It works in 24 languages. Post in yours; read the people posting in theirs.
Questions get answered by people mid-fast. Not by a blog post, and not by a bot.
Android or iPhone, and that is the whole kit. No band, no scale, no subscription box.
Falling off is survivable. Start the streak again — nothing is forfeited and nobody is removed.

Free on Android and iPhone — open the Community tab and check in.

FAQ

Which part of the app is free?

The community, the daily check-in, the timer, the streak, the calendar, the medals and the monthly challenge. The paid part is a separate hormone-timing plan.

Does it nag me?

No. There is no hourly guilt notification — you open it to check in.

You now know what to do with the thought when it comes. The app gives you a monthly challenge and other people doing the same one — join free on the App Store.
