Which Fasting App Does Reddit Recommend, And Is There A Free One?

Every Reddit thread about fasting apps asks the same two things: is it free, and is anyone else using it. FastSyncer is free to download and use, and it carries its own community feed — so the people and the timer are in the same place.

The two things every thread asks about

Free, and not empty. Those are the two complaints in every thread, and they are the two this answers.
The check-in builds a streak. Consecutive days stack up, and breaking one is visible, which is the whole point.
A calendar that fills in. Every logged day colours a square, so a month of work is one glance.
Medals for the days you did the work. They are earned by checking in, not bought.
A new group challenge on the 1st of every month. Everyone starts the same day, so nobody walks in behind.
Before-and-after photos. Post your own progress pictures and watch other people's change week by week.
Post the food you actually ate. Every post in the food feed carries a photo — up to four of them.

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

FAQ

How do I judge a fasting app without installing ten of them?

Ask what it does on the day you do not feel like it. A timer does nothing. A group that notices you missed is a different product.

Is it free to try?

The community and check-in side is free with no time limit, so there is nothing to cancel.

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.
