Every rep,
measured.

Your phone rides flat on the bar. WizeLift measures the speed of every rep and tells you when to stop and what to load next.

Runners know their pace. Cyclists know their watts. Now lifters know their speed.

No cables.

Flat on the sleeve.
Screen up.

The clip goes on the sleeve, after the plates. Your phone lies on top, across the bar, where you read it between sets.

Questions.

Is the app free?

Yes. Tracking, coaching, history, progress and leaderboards. You only buy the kit once (€29).

How can a phone be accurate?

It carries the same kind of motion sensors as dedicated VBT devices. WizeLift removes gravity, filters the noise and cancels the error every time the bar stops. Like every motion sensor, it is less precise on very slow reps near your max.

Which phones does it work with?

MagSafe iPhones (12 or later) snap on directly; other phones use the included ring stuck to the case. The app is in beta on iPhone and every kit includes access.

Will my phone fall off?

The clip grips on four silicone strips, and the phone holds to the magnet ring by MagSafe. We don't recommend it for Olympic lifts where the bar is dropped from overhead.

Shipping and returns?

Spain (peninsula) 2–4 working days, EU 4–7. Free shipping over €40. 3-year warranty. You can withdraw within 14 days; return postage is yours.
