PBros Fast tab: live fasting timer with phase and end time

Updated October 3, 2026 · General information, not medical advice.

Why people look for a no-subscription fasting app

A fasting timer does a simple job: start a clock, show when the fast ends, and keep a history. Yet many fasting apps charge a recurring fee for features like custom fasts, widgets or history, and some open with a long sign-up quiz before you can start a timer. If you just want the timer, paying every year adds up.

What you get with PBros for $4.99

  • Fasting presets: 16:8, 18:6, 20:4, OMAD, 24h and custom lengths, with the exact end time.
  • Phase notes: short, educational notes for the stretch you’re in (not lab readings).
  • Widgets and Live Activities: live fasting time on your Home Screen, Lock Screen and Dynamic Island.
  • Apple Watch app: fast, plunge, sauna and contrast timers on your wrist.
  • More than fasting: a cold plunge timer, sauna timer, contrast rounds, guided breathing and daily stack reminders.
  • No account, no ads: your history stays on your iPhone.

What to check before you pick any fasting app

  1. Total cost over a year, not the first-week trial price.
  2. What’s locked. Are custom fasts, widgets or history behind the paywall?
  3. Sign-up. Do you need an account or email to start a timer?
  4. Apple Watch and widgets, if you want to check your fast without opening the app.
  5. Where your data lives. On your device, or on someone’s server?

How PBros works

Open the app, tap a preset, and your fast is running. There’s no account to create and no quiz. When you finish, tap End fast and it’s saved to your history and streak on your iPhone. See the full fasting timer page for screenshots.

Don’t fast if you’re pregnant or breastfeeding, have a history of eating disorders, have diabetes or take medication affected by meals, or have been told not to — unless a clinician says it’s OK. Stop and eat if you feel dizzy, faint or unwell.
