Intermittent Fasting App · iOS 17.2+
6 protocols. An AI coach that reasons about your fasting state. Macro logging and workout tracking in the same app. Skip the three-app shuffle.
Free Forever tier · 7-day Pro trial · No credit card required
If you intermittent fast AND lift, you've probably tried Zero, Window, or LIFE Fasting Tracker. They count the hours fine. But your training intensity, protein hit, and recovery don't live in those apps. So you fast in one app, log meals in MyFitnessPal, track lifts in Strong, and stitch the story together yourself.
PRPath puts it in one app and adds an AI coach that reads all three. Ask Atlas "should I deadlift today?" and the answer changes based on hour 18 of a fast vs hour 4 of an eating window.
Switch protocols any day. Custom hours if none fit.
14-hour fast, 10-hour window. Great for beginners.
The most popular protocol. Skip breakfast, eat noon to 8pm.
18-hour fast. Enhanced fat-burning state for experienced fasters.
Warrior Diet. 4-hour window, typically in the evening.
One Meal A Day. 23:1 ratio. Discipline required.
Set your own fast and eating hours. Save your protocol.
Atlas is PRPath's conversational AI coach with 4 personalities (Supportive, Tough Love, Data-Driven, Toxic Mode). It sees your fasting state, last 5 workouts, last 14 days of nutrition, and weekly muscle volume when answering you.
