Fasting Signal: Phase Timer

Fasting Signal is an intermittent fasting app that doesn't just count the hours. It shows which phase your body is in right now.

■ A timer built around phases · Blood sugar stabilizing → glycogen depletion → fat burning → ketosis → autophagy → extended fast, each with its own color and explanation · Set a goal such as 16, 18 or 24 hours and start with one tap · Reminders when a new phase begins and when you reach your goal

■ A refeeding guide, because breaking the fast matters · Step-by-step advice on what to eat and when, matched to how long you fasted · Timed refeeding reminders after long fasts

■ Routines and schedules · Weekly fasting routines, skip today, next-fast reminders

■ History and insights · Fasting calendar, 7-day, 30-day and all-time stats, streaks and badges · Weight, water and meal logs

■ AI food analysis · Snap a photo or type a food name to estimate calories, carbs, protein and fat · 1 free analysis a day, then watch a short ad for each extra one (with ad removal: no ads, up to 30 a day)

■ Meet Cham · A bear whose face changes with each phase. Dress Cham up or add friends.

■ Your records stay on your phone · No sign-up. Fasting, weight and meal records are stored only on your device.

Available in 7 languages: English, 한국어, 日本語, Deutsch, Español, Português (Brasil), Français
