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 clearest difference is in-app purchases: RestTap at none against FastingWindow's 1. RestTap also leads on iOS requirement (13.0 vs 26.4). FastingWindow's advantage is ads (none vs shown) and update cadence (every 2 days vs fortnightly). On price and device support there is nothing between them.
