Everything you need to fast well
Built around how fasting actually works in your body — not around badges, points, or guilt.
One-tap fasting timer
Start and stop your fast in a single tap. A calm circular timer shows exactly where you are in your window — no clutter, no guesswork.
Six science-backed phases
From digestion to deep fast, EasyFasting explains what's happening in your body in real time — the why behind every hour you fast.
Stats & insights
Streaks, average duration, longest fast, and a weight trend you can actually read. See your progress at a glance, week over week.
Home & lock screen widgets
Check your fast without opening the app — a fasting timer and water widgets for your iOS home screen, plus a compact timer right on your lock screen.
Know exactly what's happening
Six fasting phases — from fed, through the metabolic switch, to deep fast — explained as you live them. Each phase tells you what your body is doing and why it matters, so fasting finally makes sense.
No pseudoscience, no scare tactics. Just clear, grounded explanations — honest about what research shows and where the evidence is still emerging.
Insights that keep you going
Your streak, total fasts, average and longest duration, and a weight trend you can read in a second. EasyFasting turns your history into gentle motivation — not another chore.
Track water and weight alongside every fast, all in one calm dashboard.
Why we're building EasyFasting
Most fasting apps are either overwhelming or full of pseudoscience. We wanted something different — a tracker that respects your intelligence and your time, and explains the real biology behind every fast.
Simple to start, beautiful to use, and grounded in research. No accounts to create, no noise. Just you and a healthier relationship with food.
