Gradatone vs PatchLens

Gradatone is a seamless pitch instrument: swipe the screen and hear pitch move smoothly—named for the gradient of sound. Play with nuance keyboards cannot easily offer—vocal-like vibrato and string-like glissandos. Layer timbres for rich harmony, or turn on Snap to pull pitch gently toward a scale. Choose from major, minor, Okinawan and Miyako modes, Chinese pentatonic, Indian (raga), Arabic, blues, and more. Labels include English, kana, and Indian note names (Sa/Pa). No account, ads, in-app purchases, or tracking. Settings stay on your device only. On iOS, you can play even when the Ring/Silent switch is on (use the device volume buttons).

Save synth and pedal settings from a photo, then add editable hotspots and recall notes. The demo and 3 patch records stay free; Pro Lifetime is a one-time unlock. PatchLens helps musicians capture hardware synth, pedal, and semi-modular settings as private local patch records. Take or import a photo, mark the knobs and jacks that matter, add values and notes, then search your local patch library later. Optional on-device text recognition can suggest visible panel labels, but you stay in control of every saved value. PatchLens does not require an account, does not upload your photos, and does not promise automatic universal knob or cable detection. Pro Lifetime is a one-time in-app purchase that unlocks the full local patch library, on-device OCR label assist, and recall-sheet sharing. The bundled demo and 3 patch records stay free.
