Osculatrix is a tremolo with ideas above its station. With modulated filters, delays, a bit of saturation. Like its predecessors, it is cryptic and opinionated, and it goes from subtle colouration to total destruction at the twist of a knob. Osculatrix is an AUv3 effect plugin. It does nothing on its own. Use it in GarageBand, AUM or your favourite audio application. Osculatrix does not want your money and it doesn't want your data. It is 100% free. No ads, no in-app purchases, no subscriptions, no surveillance, no nag screens.
Entonal Tuner

Tune your instrument to any scale you can imagine. Perfect harmony, or super sharp dissonance, and everything in between. Accurately recreate traditional music from around the world, as well as pre-modern western music. Or use it as a standard instrument tuner! Each scale can be selected, and its notes can be played to get a feel for it before tuning your instrument. Each scale may have a different root note (1/1), and the root note frequency (1/1) can be adjusted while tuning. Entonal Tuner was created when the developer began to learn about Just Intonation and microtonal music. He soon found that it, although some tuning apps support different temperaments and scales, they are difficult to edit, and not a "first class citizen". So the seed was planted... and Entonal Tuner was born.
