We’ve gathered 25 years of fasting experience
and put it into the Fastic app.

Here’s the background – Sebastian Wettcke, one of our co-founders, grew up with fasting as a family tradition. His parents are fasting coaches and have run a fasting hotel for the past 25 years, helping over 20.000 people. Embracing the lifestyle and knowledge themselves, our co-founders have taken this expertise and wealth of information and put it all into Fastic. Spreading balance and health, they’ve created a fasting app like no other.

Fastic is the world’s largest fasting community!

Studies show that group support helps you achieve your goals even more so than going at it alone. Our Fastic Family comes together to motivate each other in the app and on social media.

Success stories


With my weight loss of 205lbs, my life is completely different. I can completely embrace life now.


I was diagnosed with Type 2 Diabetes and have managed to get my blood sugar levels back to prediabetic conditions with Fastic. If I can do it, anyone can.


I’ve tried many diets but never stuck with them. Fasting has become a lifestyle that’s as much a part of me as breathing.
