Happy Scale vs Hevy

Happy Scale tracks weight trends by smoothing daily scale readings with moving averages, helping users distinguish progress from day-to-day fluctuation. It lets users divide a weight goal into smaller milestones and estimates future weights and the time to reach a target from current trends. The app can import and export weight entries through Apple Health when permission is granted; Apple Health is not available on iPad. Health data stays on the device by default, so a server login is not needed to record or retrieve it. Dropbox sync and backup are optional, and the app accesses only its own Happy Scale folder. Profiles can be passcode-protected. The maker says it will not share personal or health data without permission and that analytics exclude health data and personally identifiable information. Happy Scale is free with in-app upgrades. Deluxe costs $1.99 a month, $11.99 a year, or 39.99 USD once. It supports iPhone and iPad with iOS 16 or later, and Apple silicon Macs with macOS 14 or later.

Hevy is a weight-lifting workout tracker for logging sessions, planning routines, and reviewing exercise progress. Logging tools include warmup, drop, and failure sets, rest timers, exercise notes, and custom exercises. Progress tracking includes exercise charts, personal records, one-rep-max calculations, exercise videos, and workout history. Users can follow athletes, like and comment on workouts, save routines, and use the community to stay accountable. Hevy runs on Android, iOS, and the web; its web version supports routine planning, progress analysis, and viewing friends’ workouts. Apple Watch and WearOS support includes workout tracking, routine syncing, and offline workouts. The free plan allows four routines, seven custom exercises, and three months of graph history. Pro adds unlimited routines, custom exercises, and graph history, along with full body-measurement logging and Hevy Trainer. Pro costs $2.99 a month, $23.99 a year, or $74.99, paid once. Accounts are public by default, but users can enable private profiles and limit social features in Privacy & Social settings.
