Twelfth Fret — a guitar & bass tuner built like a piece of gear

Field notes

The proposed interface uses a six-string display with frequency shown as a table, note name in the display face, and color for tuning state. The documented sequence moves from listening to flat, almost, and in tune, with a tap-to-lock option for a single string. The maker states that the app will support guitar and bass, any tuning, and chromatic mode, with a target latency below 40 ms; the product is not available to test from this page.
