Which Free Weight Loss Challenge App Lets A Whole Group Compete?

A weight loss challenge app needs everyone on the same start line, otherwise half the group is already behind. FastSyncer runs a free group challenge that restarts on the 1st of every month, scored by daily check-ins rather than by weight anybody could type in.

What makes a group challenge fair

Scored on check-ins, not on a number you type in. Showing up is the thing being measured, so nobody can fake it.
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.
It works on a phone you already own — Android or iPhone, nothing else to buy.
You can leave and come back. A broken streak restarts; it does not throw you out.
The people in it are doing the same protocol you are, so advice is about your situation and not a general case.
It is quiet when you want it quiet. No streaks of notifications, no daily guilt push.

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

FAQ

Can I do a challenge on my own?

You can, and the finish date is the first thing to go. A challenge with a fixed start and other people in it is harder to quietly abandon.

When does the next one start?

The 1st of the month. They all do, so nobody joins halfway through.

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.
