NibTune

NibTune is a chiptune sequencer for iPad. Draw notes on a piano roll with Apple Pencil or your finger, and write for four channels: two pulse, wavetable, and noise. ■ Compose by drawing Place notes as if drawing a line, drag to move them, pull the tail to lengthen. The hand holding the Pencil can scroll and pinch-zoom too. Pencil, eraser, repaint, and select modes; 16th, triplet, and 32nd grids; markers and loops; onion-skin view of other channels while you edit. ■ One-handed radial menu Hold the iPad in one hand and open the menu with your thumb. Flick to switch mode, channel, instrument, or grid while your other hand keeps drawing. Menu size and column count are adjustable in Settings. ■ Four classic 8-bit voices CH1 Pulse — adjustable duty, envelope, and sweep CH2 Pulse — second square wave, no sweep CH3 Wavetable — custom 32-step waveform CH4 Noise — switchable long/short period with envelope By default you compose within retro-handheld-style limits. Free mode, which lifts them, is part of Pro. ■ Works without a Pencil Finger mode (one finger edits, two fingers scroll and zoom) is supported. Hardware-keyboard entry and editing, and VoiceOver, are also supported, with coverage expanding in updates. ■ Free to create, Pro to export Every editing feature is free. The free version saves up to 3 songs. Pro is a one-time purchase that lifts the save limit and unlocks WAV and project-file (.nibtune) export, plus Free mode. No subscription. ■ Privacy No account, no data collection, no transmission. Your songs and settings stay on your iPad. The app reaches the network only to buy or restore Pro. Requires iPad with iPadOS 18 or later. Apple Pencil recommended.
