FastLine: Fasting Timer
Lock Screen fasting timer
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
FastLine is the intermittent fasting timer that does the one thing you actually open the app for — beautifully — and doesn't charge you $70 a year for a countdown.
Start a fast and a clean count-up ring shows your elapsed time, your current stage, and how long until your goal. It lives where you'll actually see it: on your Lock Screen and in the Dynamic Island as a Live Activity, and on your Home Screen as a widget. No need to keep opening the app.
HONEST PRICING
The timer, fasting stages, history and stats are free, forever. Pro is an optional upgrade at a fair price — about twenty dollars a year, or a one-time lifetime unlock — not a $70 subscription hidden behind a countdown.
WHAT YOU GET, FREE

ON YOUR WRIST
Glance at your fast on Apple Watch and start or end it without reaching for your phone.
PRIVATE BY DEFAULT
No account. No backend. Your fasts stay on your device. FastLine reads your weight from Apple Health only if you turn it on, and never writes your data anywhere.
A NOTE ON HEALTH
FastLine is an educational tracking tool, not medical advice. Fasting isn't right for everyone — talk to a doctor before making changes, especially if you are pregnant, nursing, taking medication, or have a history of disordered eating.
