A beautiful fasting timer that turns willpower into a habit you can see. Pick your window, start the clock, and watch the streak grow — free to start, no app to install.
No calorie counting, no logging every bite. Fasting is about when you eat — and that’s far easier to keep.
Start gentle with 14:10 or 16:8. Tighten it later as it gets comfortable.
The ring fills toward your goal. Close the tab — it remembers exactly where you were.
Every completed fast counts. The streak is the quiet motivation that keeps you going.
There’s no single “best” schedule — the best one is the one you’ll keep. Free members get the two starter windows; unlock the rest in one tap.
Fast 14 hours, eat within 10 — often just skipping late-night snacks.
Fast 16, eat within 8. The most popular balance of results and sustainability.
A tighter six-hour window once 16:8 feels easy.
Fast 20, eat within 4 — one big meal and a snack.
A single daily meal. Simple by design, demanding in practice.
Get a personalized first-week plan matched to your goal — part of unlocking.
Create your free membership with just an email and get instant access to the full tracker plus your personalized fasting plan.
The tracker is free forever. Plus adds the deeper tools for people serious about the long game.
Reported benefits vary person to person, and the science keeps evolving — treat this as motivation, not medical promise.
Many report fewer afternoon crashes once the body adapts to the rhythm.
A clear window means less mindless snacking — easier to hold than a calorie count.
The streak turns an abstract goal into something you can see and protect.
You still choose what to eat. Fasting is about when — which makes it stick.
Yes — the tracker, all protocols and your starter plan are free with an email. A paid Plus tier (meal plans, insights, sync) is coming for people who want the deeper tools, but you never need it to track your fasts.
Yes. Your fast is saved on your device, so the timer resumes exactly where it left off — even after a reboot.
Water, black coffee and plain tea are generally considered fine (no calories). Sugar, milk or sweeteners can break a fast. When in doubt, keep it to water.
Most people start with 14:10 or 16:8 — gentle enough to build the habit. Tighten the window later once it feels easy.
For many healthy adults it’s well tolerated, but it isn’t right for everyone. Please read the note in the Protocols section and speak with your doctor before starting.
