echoPi: Haptic Fidget Slider

echoPi is a programmable EDC fidget slider and pocket instrument: real clicks you can tune, and a sound for every click. This free app lets you try it on your iPhone today: slide it on screen, tune the feel and the sound, and play a tune. The echoPi hardware is in development; the app works on its own. 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.
