Intermittent Fasting Timer App: Start 16:8 With One Tap

Starting a 16:8 diet means tracking your fasting hours. Checking the clock and doing the math every time gets old fast. That’s why we built FastTime — an intermittent fasting timer that records everything with a single tap.

What Makes FastTime Different?

FastTime focuses on one thing: tracking your fasting time. There’s no sign-up. No personal data sent to servers. Everything stays on your phone.

You won’t find calorie counters or meal planners here. The app answers one question: “Am I fasting right now?” That simplicity is what makes it easy for beginners.

One Tap to Start Fasting

Using the app takes seconds. Open it. Tap “Start Fasting.” Done. The screen shows your elapsed time, remaining time, and estimated end time. When you’re ready, tap “End Fasting.” Your record saves automatically.

Timer apps should be simple. That’s the same approach behind our Deep Work Timer and Breathing Timer. FastTime follows the same philosophy.

Choose Your Intermittent Fasting Timer Plan

Everyone fasts differently. FastTime supports multiple plans:

  • 12:12 — Great for beginners starting out
  • 16:8 — The most popular intermittent fasting method
  • 18:6 — For those ready to push a little harder
  • 20:4 — A challenge plan for experienced fasters
  • Custom — Set your own fasting and eating windows

Adjust the slider and you’re set. It takes a few seconds.

Your Records Build Motivation

Consistency is easier when you see progress. The calendar view shows which days you fasted. Monthly stats display your total fasting hours, daily average, and achievement rate. Watching those numbers grow keeps you going.

Smart Notifications Keep You on Track

No need to keep checking your phone. The intermittent fasting timer sends a notification when you reach your goal. “Time to eat!” — that’s all you need. Notifications arrive even when the app is closed or the screen is off.
