Counting

How should I hold the phone?

Lay it along your palm with the screen facing your palm, in either hand. A case with a strap or a grip helps it stay put. The app tracks your hand movement, not your knees.

Some reps aren't counted

Stand still when you hear "Stand still until Go": the app measures your resting position for a couple of seconds. Then clap under your knee with a clear, steady rhythm. Very small or very slow movements may not count. If you don't clap, switch to No-clap mode on the Ready screen.

What's the difference between Clap and No-clap?

Clap counts each clap under your knee, even a light touch of your hands. No-clap counts the arm movement without a clap, so it can also count other big arm swings.

Why doesn't it use the camera or a watch?

The phone's motion sensors are enough to count reps, and they work in any room and light. Nothing needs to be filmed.

Voice

How do I change the voice or its language?

The voice speaks the app's language. Change the app language in your phone's settings (iPhone: Settings › KneeClap › Language; Android 13+: Settings › Apps › KneeClap › Language). Pick a different voice in Settings › Feedback › Voice (shown when Voice count is on). Better-quality voices can be downloaded in your phone's accessibility or text-to-speech settings.

Can I turn off the spoken guide before each workout?

Yes. Tap "Skip" to skip it once, or "Don't guide me again" to turn it off. You can turn it back on under Settings › Feedback › Voice guide before start.

I can't hear the count

Check that Voice count isn't set to Off and that your media volume is up. The voice plays even with the iPhone silent switch on and mixes with your music.

Premium

What does Premium include?

Open workout (count until you stop) and custom sets (your own reps or minutes). The quick sets stay free.

How do I cancel my subscription?

Subscriptions are managed by Apple or Google. iPhone: Settings › your name › Subscriptions. Android: Google Play › profile › Payments & subscriptions › Subscriptions. Cancel at least 24 hours before the renewal date to avoid being charged. Deleting the app does not cancel a subscription.

I bought Premium but it isn't active

Open the Premium screen and tap "Restore". Make sure you're signed in with the same Apple ID or Google account you used to buy it.

How do I get a refund?

Refunds are handled by the store. iPhone: reportaproblem.apple.com. Android: Google Play › Order history.

Your data

Where are my workouts stored?

Only on your phone. There is no account and no cloud sync, so workouts don't move to a new phone. Delete them any time in Settings › Data › Delete All Workouts.

How do I turn off usage analytics?

Settings › Data › Share anonymous usage data. See the Privacy Policy for what it includes.
