Happy Scale
Happy Scale suits someone who wants weight changes viewed as a trend rather than a series of isolated readings. Its Apple-only reach is clear, and the core tracker costs nothing to start. Paid tiers add premium features, while lifetime access avoids a recurring charge. Check the lack of a named watch app and the iPad Apple Health restriction before choosing it. If you use several devices, treat Dropbox syncing as optional and verify that your profiles link correctly.
- Moving averages reduce the effect of daily scale swings.
- Milestones divide a larger target into smaller goals.
- Forecasts estimate timing for a target weight.
Hevy
Hevy suits lifters seeking an organized log, routine planning, progress records, and community accountability on phones, browsers, and supported watches. Its free tier works for a small routine collection, though regular trainers can reach the limits. Pro becomes relevant for unlimited routines, extended graph history, measurement tracking, or Hevy Trainer. Review the default public-profile choice if you prefer less sharing, and remember that API use is reserved for Pro accounts.
- Records sets, rest, notes, routines, and user-created exercises
- Apple Watch and Wear OS support includes offline workout recording
- Provides records, estimated one-rep max, volume, and exercise history

Storage and privacy controls
Happy Scale stores health data locally by default and requires no server login to retrieve it. Data leaves the device only when a user chooses Dropbox or Apple Health synchronization. The maker says it does not share personal or health data without permission; analytics are aggregate and anonymous, exclude health data and IP addresses, and use a self-hosted server. Profiles can have a device passcode. Hevy accounts are public by default, but users can enable a private profile and limit social features. Google Play reports no third-party sharing, encryption in transit and deletion requests. Happy Scale wins on local-first storage and its stated analytics limits.
