Narration will not play

Use the Play control in the bottom navigation after opening a worked example. Check the device's media volume and disconnect an unintended Bluetooth output. Narration is packaged with the App and does not require a network connection.

Edit or isolate a variable

Tap a variable tile once to edit its number. Hold the tile still for one second, then release, to isolate that variable automatically. The question-mark control opens the complete animated guide.

Answers or progress look stale

Use Clear on the current physics problem to start a fresh formula chain. If a problem persists, fully close and reopen the App; your local progress should remain available.
