Happy Scale is an Apple-device weight tracker from a United States maker. It smooths daily weigh-ins with moving averages, breaks a target into milestones, and estimates when you may reach it. Data stays on the device by default, with optional Apple Health and Dropbox sync.
There is a free plan, a trial, and paid upgrades.
What it does
Happy Scale turns scale entries into smoothed trend lines, so daily changes have less effect on the view of progress. It can split a weight-loss target into smaller milestones and estimate the time and weight at a future goal.
The app runs on iPhone, iPad, and Apple-silicon Mac. A server login is not required to save or retrieve data; local storage is the default.
On the wrist
The maker names no Apple Watch, Wear OS, Garmin, Fitbit, or other watch app. Happy Scale is a device app rather than a watch display.
It can import weights from Apple Health and send its entries back when permission is granted. Apple Health is not available on iPad.
Getting started
The free app includes core weight tracking, with in-app upgrades and a free trial. You can protect a profile with a device passcode.
You may enter weights less often than daily, although the maker says more frequent entries improve smoothing and predictions. Optional Dropbox sync carries profiles between devices and stores only Happy Scale files in its folder.
Strengths
Four smoothing choices are documented: exponential smoothing, a seven-day moving average, Happy Scale smoothing, and double exponential smoothing. Trend analysis estimates the underlying rate of loss instead of following every daily fluctuation.
Milestones, trend lines, and celebrations are described by users as motivating, while the interface is focused on weight tracking. A BMI calculator with health-category ranges is included on iOS.
Catches
There is no named watch platform, and Apple Health cannot be used on iPad. More frequent weigh-ins help the forecasts, so sparse entries may give less useful estimates.
A reported Dropbox linking problem required separate entry on each device. The maker's progress wording has also been criticized for encouraging more loss after a goal or an underweight result.
Pricing
Happy Scale is free to download with core weight tracking and optional paid upgrades. The free app also has a free trial.
Happy Scale Deluxe costs $1.99 a month or $11.99 a year. Deluxe lifetime access costs $39.99 one-time. A Happy Scale Premium lifetime purchase is also $39.99 one-time.
Who it suits
- Apple users who want trend-based weight tracking.
- People who prefer milestones to a single distant goal.
- Users wanting local storage with optional health-data sync.
Who should look elsewhere
- You need a watch app or a non-Apple mobile platform.
- You rely on Apple Health from an iPad.
- You want guaranteed multi-device Dropbox linking.
What is good
- Moving averages reduce the effect of daily scale swings.
- Milestones divide a larger target into smaller goals.
- Forecasts estimate timing for a target weight.
- Local storage works without a server login.
- Four documented smoothing methods are available.
Know this first
- No Apple Watch or other watch platform is named.
- Apple Health is unavailable on iPad.
- Dropbox device linking has been reported to fail.
- Progress wording may encourage loss after an underweight result.
The short of it
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.
