Fasted is a fasting tracker and a 16:8 timer in one app, built for people who want the habit to last past January.
No account. No paywall on the timer. Start your first fast tonight.
THE FASTING TRACKER
One tap starts the clock. Fasted follows every hour of the fast and recognises the metabolic phase your body has reached:
- Fed State (0-4h)
- Catabolic (4-8h)
- Fat Burning (8-12h)
- Ketosis (12-16h)
- Deep Ketosis (16h+)
A live timer sits on your home screen and updates in real time, so a glance is enough.
CHOOSE YOUR PROTOCOL
- 16:8 intermittent fasting — the usual starting point. Fast 16 hours, eat within 8.
- 18:6 fasting — a longer stretch inside the fat-burning window.
- OMAD — One Meal A Day. Nothing simpler.
- 5:2 — eat normally five days, cut back on two.
- 20:4 fasting — for experienced fasters aiming at deep ketosis.
- 12:12 — the gentle way in.
- Custom window — your own start time and length, down to the minute.
STREAKS THAT SURVIVE REAL LIFE
Every finished fast adds a link to the chain. Fasted counts the streak, throws confetti at the milestones and hands you streak freezes for the weeks that go sideways: a wedding, a run of night shifts, a train stuck outside Reading. There are 18 achievements across 5 categories to unlock, with share cards for the ones worth showing.
FAST WITH A FRIEND
Pair up and watch someone else's fasting timer live. Send reactions, leave comments, see who reaches ketosis first. Fasted is the only intermittent fasting app with a live partner system, and being watched beats willpower every time.

WHY SLIMMING THIS WAY STICKS
Intermittent fasting asks one thing of you: control when you eat. No food group is banned, nothing is weighed, no calorie is counted. Research consistently shows intermittent fasting reduces body fat, improves insulin sensitivity and triggers autophagy (cellular repair), and for most people it is the approach that finally holds. Whether the goal is a stone off by summer or simply a steadier week, the method is the same one you can keep.
First 16:8 or working up to OMAD, Fasted gives you the timer, the tracker, the programme and the person to keep it going.
