Most beginners can find the right notes. What stops them is timing, playing the melody so each note lands exactly on the beat, and holding that steady for a whole piece. The second wall is hand independence: the left hand keeping its own rhythm while the right plays a different one. Scales and finger exercises build strength and muscle memory, but they run at whatever tempo your hands feel like, one hand at a time, with nothing telling you that you rushed the third beat. Keyfall trains the two things scales can't. HOW IT WORKS The screen is split down the middle. The right half plays the treble staff, the left half plays the bass. Notes fall as coloured blocks, one colour per pitch class, the same seven colours used across the app, and your job is to tap the correct side at the moment the block reaches the line. Every tap is graded in milliseconds: Perfect, Good, Late, or Miss. You can play any song with your right hand, your left hand, or both. Start with one hand until the melody is in your fingers, then add the other and feel the two rhythms separate. 200+ SONGS, EASY TO HARD The library opens with single-hand nursery tunes and works up through Bach, Beethoven, Satie, Debussy and Chopin. Clear a song with both hands at 70% accuracy or better and the next three unlock. Every song shows its grade, your best score and your accuracy, so you always know what to work on next. BUILT FOR REAL PRACTICE · A guided tutorial teaches right hand, then left hand, then both · Latency calibration measures your device's touch delay so Perfect really means perfect · Tempo control from 60% to 100%, slow a passage down until it's clean · A timing breakdown after every run shows exactly where you drifted early or late, per hand · High score boards per song and per hand mode KEYFALL PRO and IMPORT MUSICXML, MIDI A single purchase, no subscription. Pro unlocks all 120+ songs at once, adds 90 pieces that sit outside the free ladder, and lets you import your own sheet music as MusicXML, MXL or MIDI, two staves map straight to the two halves of the screen. It also adds practice tools: loop a section, slow to 40%, mute one hand, and set a separate latency offset per hand. The 120+ song ladder is free forever. Pro only opens it early and adds your own music on top. No ads. No accounts required. Works offline.
