Frequently asked questions

How do I practice a knot?

Open the knot in the library, tie it with a piece of rope and rate how it went. From then on it shows up under Practice whenever it is due again. The surer you tie it, the longer the intervals get.

I don’t get a reminder.

In your iPhone’s Settings under Notifications > Deez Knots, check that notifications are allowed, and in Deez Knots under Settings > Reminders, that practice reminders are on. The reminder only comes on days when knots are due.

I’m left-handed. Can I see the knots mirrored?

Yes. Turn on “Mirror for left-handers” in Settings and the app shows every knot the way you tie it.

I bought Premium but the knots are locked.

Tap “Restore purchases” under Settings > Premium. Make sure you are signed in with the Apple Account you bought it with.

How do I cancel my subscription?

In your iPhone’s Settings under your name > Subscriptions, or in Deez Knots under Settings > Premium > Manage subscription.

How do I delete my progress?

Delete the app. That removes your practice history and settings. Premium stays with your Apple Account and can be restored after you install the app again.

Is a knot from the app safe enough for climbing?

Deez Knots does not replace training. Learn knots that hold people from a qualified instructor and check them before every use.
