INTERMITTENT FASTING · IOS & ANDROID
A live counter, evidence-labelled phases and a mascot that keeps you company. You decide when to start and stop. Blimbi just counts.

Start whenever you want (even if you forgot last night), Blimbi travels around the ring with you and celebrates when you reach your goal. That is all. And it is enough.

Forgot to open the app after dinner? Fix it in two taps, guilt-free.
What your body does at each stage, with evidence labels and sources.
