FastWindow: Fasting Timer

One-tap fasting timer. No quiz, no account, no subscription. Open the app, start your fast, know exactly where you are. Simple fasting tracking.

FastWindow does one thing. It shows you how long you've been fasting and when you can eat.

Every major fasting app has become a wellness platform — coaching subscriptions, quizzes, recipe feeds, and paywall friction. FastWindow strips all of that away.

ONE-TAP FASTING TIMER

Open the app. Tap start. Done. No quiz about your goals. No onboarding survey. No account creation. Just a clean fasting timer that works.

You see two things: • How long you've been fasting (elapsed time) • When you can eat (remaining time)

That's it. That's the app.

FASTING PRESETS BUILT IN

Choose your fasting window in one tap: • 16:8 (16 hours fasting, 8 hours eating) • 18:6 (18 hours fasting, 6 hours eating) • 20:4 (20 hours fasting, 4 hours eating) • OMAD (One Meal A Day) • Custom durations (Pro feature)

No coaching. No meal plans. No calorie tracking. Just fasting.

FEATURES THAT MATTER

• One-tap fasting timer • Live elapsed and remaining time • Fasting presets (16:8, 18:6, 20:4, OMAD) • 7-day fast history at a glance • Calendar heatmap to see patterns • Backdate your start time if you forget to start the timer • Local notifications when your fast ends • No account required. Ever. • No subscription. Ever.

WHY FASTWINDOW EXISTS

The fasting app category has a problem. Every major app pushes you toward: • Subscription upsells (coaching, premium insights, meal plans) • Onboarding quizzes (goals, weight, activity level, dietary preferences) • Wellness bloat (recipes, articles, community challenges, step tracking)

FastWindow rejects all of that.

If you need a fasting coach, use Zero. If you want recipes and meal plans, use Fastic. If you want community challenges, use BodyFast.

But if you just want to know how long you've been fasting — and that's it — FastWindow is for you.

PERFECT FOR

• People practicing intermittent fasting (16:8, 18:6, OMAD, etc.) • Users frustrated by fasting app subscriptions • Anyone who wants a timer, not a wellness platform • People who value simplicity over features • Users tired of onboarding quizzes and paywalls

WHO FASTWINDOW IS NOT FOR

FastWindow does not provide: • Coaching or fasting advice • Meal plans or recipes • Calorie tracking or macros • Community features or challenges • Water intake or step tracking • Body measurements beyond weight

If you need those features, consider Zero, Fastic, or BodyFast. FastWindow is intentionally minimal.

PRIVACY & SIMPLICITY

• No account creation required • No email, no password, no profile • All data stored locally on your device • No cloud sync (intentional — keeps it simple) • No third-party analytics or tracking • Offline-first design

NO SUBSCRIPTION MEANS NO SUBSCRIPTION

Other fasting apps say "free" but push monthly subscriptions for basic features like custom fasting durations or history beyond 7 days.

FastWindow is different: one optional upgrade, one price, lifetime access. No coaching upsells, no premium tiers, no renewal fatigue.

Free version: 7-day history, preset durations (16:8, 18:6, 20:4, OMAD), basic timer Pro version: £2.99 once, everything unlocked, forever
