Fasti: Intermittent Fasting

Your fasting window, beautifully tracked. Start a fast, hit your goal, build your streak

The Simplest Way to Fast. The Easiest Way to Stick With It.

Intermittent fasting works — but only if you stay consistent. Fasti gives you everything you need to track your fasts, nothing you don't.

START YOUR FAST IN ONE TAP Set your fasting window, hit start, and Fasti does the rest. Whether you're doing 16:8, 18:6, 20:4, OMAD, or your own custom schedule — Fasti supports however you fast.

LIVE TIMER & PROGRESS RING Watch your fast progress in real time. A clean, glanceable timer shows exactly where you are in your window — no mental maths, no second-guessing.

SMART REMINDERS Get notified when your fast starts, when you're close to your goal, and when it's time to break your fast. You focus on life; Fasti handles the nudges.

STREAK TRACKING & HISTORY Build your fasting streak day by day. Your full history log shows patterns, wins, and where you can improve — so you get better over time, not just consistent.

LIGHTWEIGHT. PRIVATE. NO NONSENSE. No account required. No subscription wall blocking the basics. No noise. Just clean, focused fasting — the way it should be.

Whether you're trying 16:8 for the first time or you're a seasoned faster optimising your window, Fasti fits your routine without taking over it.
