About
Four open strings, four bow positions.
Breaker is a brick-breaking game you steer with your violin, viola, cello or double bass. Play the G string and the bow slides to the far left. Play the E string and it slides to the far right. The app listens through the microphone and recognizes which string is sounding — there are no other controls.
At the bottom a violin bow keeps the ball in play; at the top waits the wall: sometimes colorful bricks, sometimes xylophone bars, built as a scale, a tuning fork or a fortress. The ball bounces off the bow hair, bricks burst into little notes — and from the gaps fall stars and hearts to catch, or pianos, double basses and harps you had better dodge.
WHAT IT IS REALLY ABOUT
Changing strings quickly and cleanly, without looking — an exercise nobody does voluntarily. Here you know at once whether you hit it: the bow is in place, or the ball drops. No explanation needed.
FOR VIOLIN, VIOLA, CELLO AND DOUBLE BASS
Each instrument brings its own open strings. Three speeds, from gentle to fast — for the first month of playing as much as for the tenth year. With every wall you clear, the ball gets a little quicker. Left-handed instruments are covered too: a switch flips the string order to match.
ALONE OR AGAINST EACH OTHER
• Leaderboard on your device, one entry per name
• Tournament for up to four players taking turns on the same device — everyone gets the same walls
• Challenge codes: send someone a short code and they play your exact wall sequence at the same speed — however far away they live
NO INTERNET, NO DATA COLLECTION
The sound is analyzed on your device only, while you play. Nothing is recorded, nothing stored, nothing transmitted. No account, no sign-in, no advertising, no analytics. The app opens no internet connection of its own at all.
PRICE
For fourteen days you can try everything without paying. After that you unlock the app once. No subscription, no recurring costs.
WHAT YOU NEED
An instrument in tune and a reasonably quiet room. The built-in microphone is enough — no extra equipment.

New: a switch for left-handed instruments — the string order flips to match. Also: rotating the device no longer resets the wall you were smashing.
