*2026-03-04*

They offer 7 days trial but they charge you 
Don’t accept or you will be charged

### 2/5 — Are you kidding me

*2026-02-08*

A one wheel gen app that you can’t barely control generating one frequency that’s obviously wrong as you scale up !!!! It goes too high and doesn’t go under 20Hz so you’re lying in your description … I don’t usually write reviews but you can get ten times better for free
