Fast Forward Evolution: Fasting & Fat-Burn Tracker. Two rings. One clear picture of your fast.

Fast Forward Evolution tracks how long you've been fasting and how long you've actually been burning fat — separately. Because they're not always the same number.

The Fast Timer: Counts up from the moment you start your fast, straight through to your goal — 12:12, 16:8, 18:6, 20:4, OMAD, or an extended protocol. It only cares about time.
The Fat-Burn Ring: Runs independently, and tracks how long you've stayed under a 49g carb threshold. Go over it — even mid-fast — and the ring resets, even though your fast timer keeps climbing. It's the honest number your fast timer alone can't show you.

Fasting Phase Reference

Drag the slider to see what's happening in your body at any hour of a fast.

Fed State
0 – 8 Hours

Your body is processing your last meal. Blood sugar and insulin are elevated. Your body is burning glucose for energy. No fat burning is happening yet.

No other fasting app does this. A future "Export for Doctor" button turns your fasting streak, meal log, weight trend, and adherence into a clean, printable report a doctor or nutritionist can actually use — generated entirely from a QR code or link, with no account and nothing stored on a server. Includes a plain-language phase glossary and methodology notes built for clinicians, not just users.

Why Fast Forward

Built different, on purpose

01

Dual-Ring Tracking

Fast timer and fat-burn ring run independently — a distinction most fasting apps don't even track.

02

No Paywalled Basics

Core fasting, meal, and weight tracking isn't locked behind a subscription wall.

03

One App, Not Five

Fasting, meals, weight, hydration, and heart rate in a single place instead of five disconnected apps.

04

Built By Practitioners

Made by people who actually fast — not a generic health-app template with fasting bolted on.
