23+ hours fasting, one meal. Maximum discipline and simplicity.
HonestFast Premium lets you create custom fasting plans from 10 to 48 hours - for every fasting style from 12:12 to extended multi-day fasts.
As your fast progresses, your body moves through distinct metabolic states. HonestFast tracks your current stage in real time so you always know exactly where you are in your fast.
From the initial fed state all the way to deep autophagy, see your current stage update as you fast - and understand what your body is doing at every step.
Body digesting and absorbing nutrients from the last meal
Blood sugar normalizes, insulin drops, glycogen begins depleting
Glycogen stores depleted, body switches to burning fat for fuel
Liver produces ketone bodies; brain and body run on ketones
Cellular cleanup begins - damaged cells are broken down and recycled
Peak cellular renewal and immune function regeneration
HonestFast includes a dedicated Ramadan mode with tools designed specifically for fasting during Ramadan - from automatic Sehri and Iftar times to prayer times and Qada tracking.
HonestFast uses the Hijri calendar to automatically detect Ramadan. No manual setup needed - the app knows when Ramadan begins and switches to Ramadan mode.
Astronomically calculated Sehri (Suhoor) and Iftar times for your exact location. Set individual reminders so you never miss Sehri or Iftar.
Full prayer times for your location - Fajr, Dhuhr, Asr, Maghrib, and Isha. Supports both location-based and city selection for accurate times worldwide.
Track missed Ramadan fasts and your Qada (makeup) fasting. Keep a clear record of which fasts still need to be made up throughout the year.
Plan and track voluntary Islamic fasts alongside your regular routine. Track Ramadan, Qada, and voluntary Sunnah fasts in one place throughout the year.
Log voluntary Sunnah fasts from Fajr to Maghrib. HonestFast calculates the fast duration automatically based on your local prayer times.
Live Activities show your fasting timer, progress, fasting plan, and start and end times directly on the Lock Screen and Dynamic Island - so you never need to open the app to check how long you have been fasting.
Log water directly from your Live Activity during supported fasts, without unlocking your phone.
Staying hydrated during a fast is essential. HonestFast makes water logging frictionless - and keeps a complete record of every fast you complete.
Log water from the app or directly from your Lock Screen Live Activity. Daily water count resets automatically and syncs across Apple devices.
Build consistency. See your current and longest fasting streaks, and watch your discipline compound over time.
Review completed fasts with full details - duration, fasting plan, and metabolic stage reached. Create share cards to celebrate milestones.
View fasting trends, heatmaps, plan performance, and metabolic stage analytics. Understand how your fasting routine changes over time. (Premium)
