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.

Verdict

The call

The clearest difference is monetization model: Window at free against FastingWindow's free with in-app purchases. Window also leads on iOS requirement (17.6 vs 26.4). FastingWindow's advantage is update cadence (every 2 days vs every 9 days). On price, rating, ratings volume and ads there is nothing between them.
