Write to [email protected]. A person reads it, usually within two working days. Say which device you are on and, if something went wrong, which model you were folding.
A model is locked. What do I get for free?
122 of the 148 models, every hint, every symbol and the whole glossary — forever. The first three steps of any paid model are free to try, and the progress you make in them is kept.
I paid but nothing unlocked.
Open any paywall and tap Restore Purchase. Purchases are tied to your Apple Account, so use the same one you bought with. If it still does not appear, write to us with the date of purchase.
How do I cancel a subscription?
Subscriptions are managed by Apple, not by us: Settings → your name → Subscriptions, or tap Manage subscription in the app’s Settings. Cancel at least a day before the period ends. Lifetime never renews.
Voice steps are not working.
Turn on Voice control in Settings → Sound & hands-free; that switch is what asks for speech recognition and the microphone. Recognition runs entirely on your device, so a device that cannot recognise your language on-device will decline rather than send your voice anywhere. The buttons and swipes always work.
How does the Apple Watch app work?
It installs with the iPhone app. It controls the player — you choose models on the phone. Rotate the Digital Crown to close a fold. Progress syncs both ways whenever both apps are open, and is queued when they are not.
Does it work offline?
Entirely. Every model, lesson and diagram is in the app. The only thing that needs a network is buying or restoring Plus.
Which languages?
English, Tiếng Việt, 日本語, Español and 简体中文 — names, steps, tips, lessons and glossary, all of it. Switch in Settings and the whole app reloads in the new language.
