Core Features

⏱️ Smart Fasting Timer & Presets

Track your elapsed and remaining fasting duration with a premium, smooth visual progress ring. Choose from 5 presets representing key biological and metabolic phases:

Anabolic Phase (0–4h): The body digests your last meal and stores glucose.
Catabolic Phase (4–16h): Blood glucose levels fall and glycogen storage is utilized (Ideal for standard 16:8 plans).
Fat Burn Phase (16–24h): Gluconeogenesis begins and fat stores become the primary energy source.
Ketosis Phase (24–72h): Ketone production increases, enhancing mental clarity and cellular repair.
Deep Ketosis (72–96h): Prolonged fat burning and metabolic adaptation.

🏝️ Live Activities & Dynamic Island

Keep track of your active fasts without unlocking your phone.

Lock Screen Widgets: Real-time updates showing elapsed time and progress.
Dynamic Island Support: A persistent battery-style indicator visualizes your current metabolic phase (Anabolic to Deep Ketosis) dynamically as you go about your day.

No. FastFaster operates entirely on-device. Your weight and workout data are requested from and saved directly to Apple's HealthKit database. We do not run external servers, and your data is never sold or shared.

Can I track custom fasting plans?
