Fastly: Fasting Timer

A calm, focused intermittent fasting tracker — no noise, no guilt, no ads.

Fastly keeps the whole routine on one screen: your fasting window, what you drank and ate, and the streak you are building.

◆ ONE CLEAR TIMER
• Start and end a fast in a single tap
• Live ring showing elapsed time, remaining time and your goal
• Popular schedules: 12:12, 14:10, 16:8, 18:6, 20:4, OMAD and custom windows
• Edit any past fast — notes and mood included

◆ FUEL: PROTEIN AND WATER
• Daily protein target calculated from your own body details
• Quick-add presets so logging takes a second
• Water tracking with your preferred unit
• Weekly weigh-in reminders instead of daily weighing

◆ UNITS THAT FIT YOU
kg, lb or stone. cm or feet and inches. ml or fl oz. Pick each one separately — Fastly starts with the units common in your region and you can change them any time.

◆ STREAKS AND HISTORY
• A streak that survives a rest day each week
• Calendar view of every fast
• Trends for average fast, longest fast and goals reached
• Weight chart you can tap to inspect any point

◆ FASTING GUIDE
Ten short, practical reads — hunger waves, breaking a fast gently, hydration, protein basics, sleep, light movement, choosing your window, common pitfalls, consistency and what the fasting stages actually mean. Save one for the last hour of a fast; reading is a great distraction.

◆ GENTLE REMINDERS
Fast start and fast end reminders are free. Premium adds stage updates, hydration nudges and streak reminders. Nothing is framed as failure — a missed day is a data point, not a verdict.

◆ PREMIUM
Fastly Premium unlocks every fasting plan, home screen widgets, advanced reminders, unlimited history, 30/90 day and all-time trends, Health sync, every theme and data export. Available monthly or yearly. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; manage or cancel any time in your Google Play account settings.

◆ MADE WITH CARE
• No ads, ever
• Works offline
• Available in 11 languages
• A sensitive mode that hides weight features entirely
