A popular budget Bluetooth scale that Tom's Guide picks as best for body fat, for its 13 metrics, unlimited profiles and informative app. It reads in 0.2 lb steps and rounded up in testing, and Wirecutter's testers disliked its small red digits and found it wobbled.

Subscription: None: no subscription mentioned by testers

Top complaints

  • Reads in 0.2 lb steps and rounds up

    Tom's Guide says it shows only even decimals and rounded up; with weight plates it routinely read slightly heavy.

  • Hard-to-read display and wobble

    Most of Wirecutter's paid testers disliked the small red numbers (the decimal point was especially hard to see), and the scale wobbled for some. Tom's Guide notes the display shows only weight.

  • One login for all users, no Wi-Fi

    Tom's Guide lists that all users must share the same app login, and that the basic model has no Wi-Fi.

What owners love

Good for

Scores (tap for why)

  • Weight accuracy & consistency3.0
    Why 3.0?Reads in 0.2 lb steps and read slightly heavy with weight plates (Tom's Guide). Wirecutter testers found the decimal hard to see.
  • Body composition (as tested)3.0
    Why 3.0?Tom's Guide picks it as best for body fat for its 13 metrics, but publishes no comparison against a reference device.
  • App & syncing4.0
    Why 4.0?Well-designed app with broad syncing (Tom's Guide), but Bluetooth only and the phone must be nearby.
  • Multiple users3.5
    Why 3.5?Unlimited profiles, but all must be under the same app login (Tom's Guide).
  • Durability & battery3.5
    Why 3.5?Tempered glass; AAA batteries last several months (Tom's Guide). It wobbled for some Wirecutter testers, and 4% of Amazon ratings are 1 or 2 stars.

What experts say

  • Tom's Guide: Best for measuring body fat (updated 2026-07-22). The cons are 0.2 lb rounding, no Wi-Fi on the basic model, and one shared app login.
  • Wirecutter (NYT): In 'The competition': testers disliked the small red digits, and it wobbled for some.
