### 3/5 — [no title]

*2024-09-29*

I understand the whole ‘money’ thing, but premium for a polyrhythm app? AND you need premium for almost everything? 
Not very cool.
:(

**Developer response:** Hi, moonlight the Protogen! 
Thanks for sharing your feedback. While some of our premium features are available through a subscription, we’ve also made core functionalities and a selection of rhythms accessible for free, to give everyone a feel for the app’s value. Plus, with our ad-free experience, we hope you can enjoy uninterrupted sessions. 
We appreciate your support and are always working to create the best experience possible!

We are very sorry that you did not have enough free content in our application.
