Four octaves of true glide
Pitch runs continuously across four octaves, so you can slide between notes the way a physical theremin does instead of stepping through fixed keys.
Slide a finger and play tones no keyboard can.
Hovertone turns the whole screen into a theremin. Left and right changes pitch, up and down shapes the volume, and the result is continuous, gliding sound rather than a grid of fixed notes.

An instrument, not a toy
Volume down to true silence
Vertical movement follows a shaped volume curve that fades all the way to silence, which makes swells and phrasing part of the performance rather than an afterthought.
Tracking you can trust
Rock-solid single-touch tracking ignores stray touches, and the instrument recovers gracefully from calls, audio route changes, and other interruptions.
Shape the sound your way
Four waveforms
Sine, square, triangle, and sawtooth give the same pad four distinct voices, from soft and pure to sharp and buzzy.
Reverb and delay
Two effects add space and echo to a performance without turning the instrument into a mixing console.
Scale snapping, when you want it
Snap to major, minor, or pentatonic scales when you want to stay in key — or switch snapping off and play the raw, continuous pitch space.
Playable by more people, private for everyone
Accessible by design
VoiceOver users get assistive pitch and volume sliders, so the instrument is playable without relying on the visual pad alone.
Motion respected
Reduce Motion is respected throughout the app, so playing does not depend on animation-heavy feedback.
Nothing kept
There is no account, no recordings, and no tracking. Hovertone is an instrument — it makes sound and keeps nothing.
Pre-release availability
Hovertone is in active development for iPhone and iPad and is not yet available to download, so this page intentionally provides no App Store offer, price, or promised launch date. The planned free experience is a genuinely playable instrument: the full pad, the sine waveform, and reverb, free forever. Optional Lifetime Access — a one-time purchase, no subscription — unlocks all waveforms, the delay effect, and scale snapping. Hovertone is best experienced with headphones or a decent speaker.
Maker note
Why continuous pitch is the whole point
Most touch instruments quantize everything, which makes them easy but interchangeable with a keyboard. I built Hovertone around the one thing a flat screen genuinely does better: uninterrupted glide. That is why pitch runs continuously across four octaves, why the volume curve fades to true silence instead of cutting off, and why scale snapping is an option you can switch off — never a cage.
Daniel · solo developer behind Crafter AppsHovertone questions
What exactly is Hovertone?
A touch theremin for iPhone and iPad. The whole screen is the instrument: sliding left and right changes pitch across four octaves, sliding up and down shapes the volume, and tones glide continuously instead of stepping between fixed notes.
What is planned to be free, and what does Lifetime Access unlock?
The pad, the sine waveform, and reverb are planned to be free forever. Lifetime Access — a one-time purchase, no subscription — unlocks all waveforms, delay, and scale snapping.
Does Hovertone record audio or collect anything?
No. There is no account, no recordings, and no tracking. It generates sound while you play and keeps nothing.
Is it usable with VoiceOver?
Yes. VoiceOver users get assistive pitch and volume sliders, and Reduce Motion is respected throughout the app.
When can I download it?
Not yet — Hovertone is an active pre-release project, and this page deliberately shows no App Store badge, offer, or price. It ships when it meets the studio bar, and no launch date is promised here.
