The German fasting app with 5,000+ Trustpilot reviews - more than just a timer with AI food scanning and recipes.
What is Fastic?

Who Should Look Elsewhere

- Exercise focused: Exercise integration is limited
The Bottom Line
Fastic stands out from basic fasting timers by combining fasting tracking with calorie counting, AI food scanning, and a recipe library. The 5,200+ UK Trustpilot reviews suggest a substantial, engaged user base, and the weight loss results people report are impressive.
The premium pricing is steep compared to dedicated fasting timers or calorie counters used separately. But if you want everything in one app and are willing to pay for convenience, Fastic delivers a comprehensive package.
Our verdict: Worth trying if you want fasting + calorie tracking combined. Watch out for the billing - make sure you understand what you're signing up for before entering payment details.
