## What is echoPi?

echoPi is an EDC fidget slider you can tune and play. This app is where you shape it.

TRY THE FEEL
Drag the slider on screen. Every click, buzz and sound plays the way you set it. Your phone can only approximate it. The real feel is on echoPi.

TUNE THE FEEL
Seven stops. Make each one a click or a smooth glide, and give it its own vibration: set how strong and how long. Start from a preset and change what you like.

TUNE THE SOUND
Pick a sound for every click, play a melody one push at a time, or turn the seven stops into seven keys.

PLAY ALONG
Push along with the notes and go for Perfect.

YOURS, ON YOUR PHONE
Works offline. No account, no sign-up. Your creations stay on your phone.

HARDWARE PROGRESS
echoPi is in development. The home screen shows where the hardware is, stage by stage. Specs are design targets and may change before launch.
