Log your weight in seconds. See the trend over time. Keel makes a daily weigh-in simple: one number, a clear chart and a seven-day average that helps you see beyond everyday fluctuations. - Log in kilograms or pounds. - See your recent weights and seven-day average. - Set an optional target and a daily reminder that fits your routine. - Edit a weight or undo a change. - Connect Apple Health, free and entirely optional. Share the weights you log from then on, or bring in existing weights with a one-time import. Keel keeps days you have already logged and imports one reading per missing day. No account. No advertising. No analytics. Keel stores your weights on your device. Your weights are never sent to Mono Studio or our servers. If you choose to connect Apple Health, Keel can save weights to Health and import the weights you allow it to read. Apple Health may sync through Apple's services according to your device settings. You control access, and Keel never edits Health entries created by another app.

Verdict
The clearest difference is update cadence: Fasting Tracker Pro at every 3 weeks against Keel's every 5 months. Keel's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
