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.

Weight Log: Daily Tracker is a simple, beautiful app for tracking your weight and celebrating your progress โ€” no matter how non-linear that progress looks. Log in seconds. Just tap Log, enter your weight, and you're done. Add a note if you want context โ€” how you're feeling, what changed, what you're proud of. Or keep it simple. Either works. See your journey. A clean, minimal chart shows your weight trend over time. At a glance you can see your high, your low, and how far you've come. The data doesn't lie โ€” and over time, the downward trend is deeply motivating. Stay consistent with streaks. The app tracks how many days in a row you've logged. Miss a day and your streak resets โ€” which turns out to be a surprisingly powerful motivator to just show up. Earn badges along the way. From your very first entry to hitting your goal weight, Weight Log celebrates every milestone with a badge. First Step, Week Warrior, Halfway There, Goal Crusher โ€” each one is a small reminder that you're making real progress. Set a goal, track your progress. Enter a target weight and the app shows you exactly how close you are as a percentage. Watching that number climb toward 100% never gets old. Daily reminders that don't feel repetitive. Turn on a reminder and we'll nudge you at the same time every day โ€” with a different encouraging message each time so it never feels like spam. Your data, your way. Switch between pounds and kilograms anytime. Export your full history as a CSV whenever you want. Your data is always yours. Private and secure. Sign in with Apple to keep your data backed up across devices and reinstalls. We never see your Apple ID or sell your data. Ever. Progress isn't linear. But showing up โ€” every day, one entry at a time โ€” is how it happens.
