AUv3 Midi sequence generator which generates musical evolving sequences that you can further automate or modulate via midi. A clever algorithm creates a musical sequence which is output as a midi signal which can be used to drive a software synthesiser or a hardware device. Various settings allow the sequence to be constrained to scales and chords, transposed on the fly and also allowed to gently mutate giving an evolving sequence. All the controls can be modulated or automated via midi. Needs a AU host like AUM and generates no sound on its own. "My solution has been to make the equipment unreliable in various ways." - Brian Eno

Verdict
The clearest difference is update cadence: Autony at every 5 days against TriKey's every 2 months. Autony also leads on price ($3.99 vs $9.99) and device support (3 vs 1). TriKey's advantage is iOS requirement (12.0 vs 15.6). On ads and in-app purchases there is nothing between them.
