Build, trade, pay and replay
Choose one of 36 guided missions or practice Pay Exact, Make Change or Trade First. Tap a drawer coin to move it into the tray; tap a tray coin to return it. In Trade, choose money to Give and Get with the same total value. Your trade changes the coins you can use. Check accepts any exact combination your inventory permits. Undo restores an unfinished step. Replay shows your actual steps, and a receipt records the completed round. Learning activities use educational practice money.
Seven-day trial, Lifetime and restore
Installing the app does not start the trial. Open Parents and complete the grown-up multiplication check, then choose Start 7-Day Full Trial. The trial lasts seven full days from Apple’s verified transaction date. There is no subscription or automatic renewal. Unlock Forever is a one-time Lifetime purchase; Apple’s current localized price is shown before purchase. Use Restore Purchases with the Apple Account used to buy. Pending access begins after Apple approves the purchase.
When the trial ends, new learning rounds require Lifetime access. An already-started round can finish. Saved receipts, Replay, backups and parent settings remain available. Purchase restoration does not restore detailed learning history. If products are unavailable, retry in Parents when connected; avoid deleting the app to troubleshoot a purchase.
Saved steps, backups and iCloud
Confirmed coin moves and trades save on this device before success is shown. Continue resumes an active round. Export Learning Backup before moving devices, and Restore Learning Backup to import the JSON file. Keep exported files private. Optional iCloud sync merges only completed guided mission progress, not live coins or detailed Replay. If iCloud is unavailable, local learning continues. Reset creates a local safety copy; cloud progress may return if sync remains on.
Sound, accessibility and help
Sound can be turned off in Parents. Text and coin controls remain available without audio. All coin and trade actions have tap controls; dragging is not required. The app follows system text size and appearance. A parent can email the app version, device model and a short issue description. Please do not include children’s personal information or a learning backup.
