LockOn is an ultra-precision tuner in a minimalist package. Its unrivalled ability to track ultra-low pitch on stringed instruments quickly and accurately is its defining feature.

The rapid, vector-based dual strobe/cents-meter display offers the best of both worlds, allowing extreme tuning precision in an intuitive package.

The UI is infinitely resizable, allowing for both 'fast' and 'slow' tracking modes so you can tune exactly how you want.

LockOn comes in both free and pro variants:

The free version notifies users of product deals on the SubMission Audio store via an in-app banner. The pro version removes the banner and the 'free' logo.


Tuning Range: C0 - B8 (so drop C... and then down another octave!)

Frequency Range: 14Hz - 8kHz (that's lower than human hearing!)

Dual Display: Cents-based LED bar tuner & rotating strobe tuner for maximum precision.

Tuning Speed: Choose between 'Fast' and 'Slow' tracking speeds, to suit your preference.

Display Preference: Choose whether the display denotes sharps or flats, depending on your musical sensibility.

Reference Frequency: Alters the tuner's foundation by adjusting the base calibration frequency. Default is A = 440Hz.

Mute Output: Silences the output.

I use an actual pedal strobe tuner when recording because I could never get an in the box one to really register the low G on my 7 string. But lo and behold we have a winner with Lock on. And its free! Thank you so much Submission Audio!
