Description
Fastly is a clean, private fasting timer for 16:8, 18:6, OMAD, and custom schedules—without ads, accounts, or distractions.
Start a fast with one tap, adjust your start or end time when needed, and see your elapsed time, remaining time, and planned finish at a glance. Fastly keeps the experience focused while giving you the tools you need to understand your routine and track your progress.
FOLLOW YOUR FAST
See estimated fasting phases based on your elapsed fasting time, including digestion, fat burning, ketosis, and autophagy. Upcoming phase markers make it easy to see what comes next during your fast.
TRACK YOUR PROGRESS
Review your complete fasting history through clear statistics, charts, and progress insights. Set weight and body fat goals, and optionally connect Apple Health to keep your measurements organized.
STAY ON TRACK EVERYWHERE
Follow your fasting status from your iPhone, Apple Watch, Home Screen widgets, and complications. Smart reminders help you stay aware of fasting goals and eating windows without unnecessary interruptions.
