A big redesign. - Home: the real echoPi, rendered from its model. Push and the lid slides to the stop. Your pushes today, with the last two weeks as bars. - Play: one song fills the screen. Big title, one tap to start. - Create: seven faders, one per stop. Slide to set how firm each stop feels. - Me: a watch dial for your creations; it fills as your streak grows. - Connect a real echoPi over Bluetooth and tune its sound (for boards that support it).

Send your sound to a friend with a link: they can hear it and push the plate in a browser, no app needed. Sign in with Apple, Google or email if you like, and your creations follow you to a new phone. Push the plate right from the first screen. Six new original short tracks with two new sounds, shorter songs at the easy levels, a simpler Try the feel page, and a download half the size.

A fresh look: clearer buttons, product shots on the create screen, a tidier Me page, and a metal glint when the plate clicks into a stop.

New: record your own sound. Turn a sound around you into your push sound, and π can tell you which ones to keep. Also new: a Home Screen widget. Tap either half of the slider to push it one stop, with sound and haptics; stand it up or lay it flat.

- Every push feels better: the click sounds faster, and the haptics build up as you push faster. - Each push brings color back to a world behind the slider. Light one up fully and the next world begins. - Play along now has Relax mode (no game over) and Challenge mode.

- Looks right on iPhone Duo unfolded and on larger screens. - Custom mode: set the sound and buzz of every stop. Pushing on and pushing back can differ. - Save the feel you tuned, give it a name, and change its colors. - Play along: a quick how-to before your first song, a beginner shield until your first clear, Today's song, and a day streak. - Sweep notes: swipe all the way to the end for the big click. - After a clear, go straight to the next song. - Privacy: you can now use echoPi without sending anonymous usage counts, and change it anytime in Me. - The default click plays fuller at the default volume. - Get launch news by email, right in the app.
