UpReady

Raw numbers from a wearable rarely tell you whether to train hard or take the day easy. UpReady is an AI health app that turns Apple Watch data into a readiness score, so you can decide how much to push before you start.

It also tracks a load score, and you can share both readiness and load with people close to you.

The app reads from Apple Health and works with Polar arm bands.

You need a compatible Apple Watch (Series 10, SE or higher, or Ultra) or a Polar arm band, so it is no use without one of those.

UpReady says it does not store your health data, which matters for something this personal.

Its scores are only as good as the readings the watch or arm band produces, and full access needs a subscription.

If you already wear an Apple Watch daily, the setup is light.
