How to choose
- Compatibility with Lose It App. Ensure the scale directly connects to Lose It or via an intermediary app like Apple Health or Google Fit. Most Wi‑Fi scales sync automatically, but Bluetooth models require the app open.
- Metrics Measured. Beyond weight, consider body fat, muscle mass, bone density, and water percentage. More metrics give a fuller picture of health but may increase cost.
- Connectivity Method. Wi‑Fi scales log data automatically without your phone nearby, while Bluetooth scales require proximity. Dual‑band Wi‑Fi offers more reliable connections.
- Setup and User Profile. Look for scales that auto‑recognize multiple users (via weight or profile) to avoid mix‑ups. Some apps require manual profile creation first.
- Build Quality and Display. Tempered glass surfaces are easy to clean and durable. A large, backlit display helps readability in any lighting. Battery life varies from 6 months to a year.

Is a Wi‑Fi scale worth the extra cost?
If you want automatic logging without needing your phone nearby, yes. For those who always carry their phone, a Bluetooth scale works fine and costs less.
Will my old data transfer to Lose It from another app?
Lose It imports historical weight data from Apple Health, Google Fit, and some partner apps. However, super old data may not appear; you can manually enter past weigh‑ins.
