Wellograph

Elegant design. Rugged. Automatically goes into power-save mode when off the wrist.

Expensive. Requires excessive babysitting (manual adjustments). Inaccurate step and mile counts. Inaccurate heart rate readings. Doesn't measure sleep. No background syncing.

Plus, your Fitness Age and other guesstimations in Wellograph's app and watch depend on it being accurate in the data it does collect. And in my testing, well, the results weren't good.

Accurate sleep tracking ; Good battery life ; Beautifully-presented activity data

Inaccurate heart-rate data ; Incaccurate step counts ; Sits high off the wrist

An unusual but elegant design and captivating data display are plus points, but the Wellograph’s inaccurate readings let the side down
