Which Free Accountability Partner App Actually Makes You Check In Daily?

An accountability partner app only works if the check-in is small enough to do every day and public enough to matter. FastSyncer is free and does exactly that: one daily check-in, visible to the group, feeding a streak that breaks the moment you skip a day.

What to look for in an accountability app

Small enough to do daily, public enough to count. Thirty seconds, and the group can see it.
No application, no waiting to be let in. You are in the group the moment you check in.
A fasting timer that runs while the app is shut. Start it, forget it, check in when it ends.
Your own numbers, charted. Hours fasted, days held, the trend over weeks.
Nothing to configure before you start. Install it, check in, you are going.
Posts can be long when they need to be — up to two thousand characters, and four photos.
You see people at every stage, not just the finishers. Week one is in the feed next to month six.

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

FAQ

Why an app and not a friend?

A friend gets busy, and asking them to audit your eating for months is a real favour. A check-in a group sees costs nobody anything.

What does it cost?

The check-in and the group are free with no time limit.

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.
