How does the No Carbs Challenge work?

Pick a challenge (No Carbs, No Sweets or both) and a goal from 7 to 90 days, then check in once a day as clean or a slip. The app tracks your streak, best streak and clean-day rate.

What happens if I slip?

You log it honestly and keep going. The clean-day rate and calendar show the real picture; one slip does not erase your progress.

Yes, the daily check-in, streak and 14 days of calendar history are free forever. Pro adds multiple challenges, custom goals, full history and a widget.

No. The app is an accountability tracker; it gives no dietary or medical advice. For diet changes with health implications, talk to a professional.

§ Overview

What it does

Breaking free from sugar and carbs is hard; staying accountable does not have to be. Pick a challenge (No Carbs, No Sweets, or both) and a goal of 7, 14, 21, 30, 60 or 90 days, then check in once a day.

Log a clean day or an honest slip and the app keeps score: a live streak, a best-streak record and a clean-day rate. A progress ring and a color-coded calendar make real progress impossible to ignore.

The core stays free forever: your daily check-in, your streak and 14 days of history. Pro adds parallel challenges, custom goals, full history and a home screen widget.
