FastingWindow is the cleanest, simplest way to track intermittent fasting — no account, no subscription, no noise. Pick a schedule (16:8 or 12:12), tap Start Fast, and watch your progress in real time. A live ring shows exactly where you are in your fast, and as the hours pass you'll move through five metabolic stages — from initial digestion all the way to deep ketosis. Each stage is explained so you actually understand what your body is doing, not just how long you've been waiting.
