I bought the upgrade and it hasn't appeared

Open the app's Settings and tap Restore purchases. Make sure you're signed in to the same Apple Account you bought it with. If it still doesn't appear, email us with the date of purchase and we'll look into it.

Can I move my data to a new phone?

Yes — everything is included in your device backup. Restore the new phone from that backup and your data comes with it. There is no account and no cloud sync, so a fresh install on a new device starts empty.

How do I remove the ads?

Settings → the ad-removal purchase. It's a one-time purchase, not a subscription.

Is Kneelog medical advice?

No. Kneelog is a diary. It records what you tell it and shows it back to you. It does not diagnose anything, does not recommend exercises, and does not tell you what your recovery should look like. Follow your surgeon and your physiotherapist.

If something feels wrong — sudden severe pain, a fever, a hot or red knee, or calf pain and swelling — contact your care team straight away.

Why are there no exercises built in?

Deliberately. Your programme should come from the physiotherapist who has examined your knee, not from an app that hasn't. Add what they gave you and tick it off.

How do I get the report for my appointment?

Progress → For your appointment → Create report. It produces a one-page PDF you can print or email. This is a Pro feature.

Do you collect any of my data?

No. Everything stays on your device. See the privacy policy for the full detail, including what the advertising provider handles.

I found a mistake in a calculation
