SUS4 Pedal Tuner
Floor-mode tuner: big display, mute control, stomp-box feel.

SUS4 Pedal Tuner is a floor-mode tuner with a large display and mute control: the layout and feel of a hardware stomp-box tuner, on iPhone, iPad and Mac. It is designed for live use, where you need to read the display from a distance and mute the signal while you tune.
The display is optimised for readability under stage lighting: high contrast, large numerals, clear sharp/flat indication. The mute control is a large tap target so you can engage it reliably without looking precisely at the screen.
In a live context, a tuner that is hard to read or fiddly to operate is worse than useless. It breaks your on-stage flow. SUS4 Pedal Tuner is designed to work the way a dedicated hardware tuner works, without the additional item on your pedalboard.
