User reviews

Superb for Sight Reading Practice

An excellent app that has really improved my sight-reading and rhythmic accuracy. The flexibility is superb, with so many options to create exercises tailored to your needs. As with all of Joe Crabtree’s work, the app is regularly updated, thoughtfully developed, and beautifully polished. Highly recommended for drummers wanting to take their reading and timing to the next level. Paul

Response from developer

Thanks for the kind words. It’s been fun developing it and I’m looking forward to adding more features!

Compound Time Beaming

Would be so nice if 6/8, 9/8, etc. were beamed properly.

Great Classroom Tool

This app helps so much in my classroom rhythm training exercises. Much more efficient than writing rhythms on the fly or using a set of cards that students end up memorizing.

I love that you can set it to generate a new rhythm every x repeats and that it can get progressively harder

Completely worth the purchase!

Thanks for much the the great review. I’m so pleased you’re finding useful in the classroom. Best, Joe

Constantly demanding payment

They call it free? Every time I hit the play button it just gives two options: pay every month or pay every year. Choosing Maybe later doesn’t free the app to continue functioning.

Response from developer

Hi, It’s free to play levels 1-4, or rhythms from the library (when you tap Shuffle at the top), or rhythms scanned from QR codes. You should only see the paywall if you’re trying to play a rhythm of a higher level, or shuffle a pattern from the library. If that’s not the case, please email me at support@polynome.net so I can help you get it working again. Best, Joe

Predatory paywalls

It puts paywalls to hear rhythms. This stoops to a new low as instead of gatekeeping features they limit your ability to play certain rhythms.

Response from developer

Hi there! I really appreciate you trying out Rhythm Generator and taking the time to leave a review. I totally understand how paywalls can feel frustrating, so let me explain how this one actually works: • I built the app so it’s free to install and you can generate as many rhythms as you like, no limits. • You can also play back basic rhythms at no cost—perfect for building your skills and experimenting. • When you try advanced rhythms, that’s when the small, clearly‑shown subscription prompt appears. That means you can see what advanced features cost before committing—but you don’t have to subscribe unless you choose to. So there’s no sneaky trick here—just a soft paywall that preserves free access to most features and only asks for support when you want more complexity. I wanted to make sure you can really experience the app first. If the advanced rhythms feel valuable to you, great—your subscription supports continued development. If not, no pressure at all. My hope is that this setup is respectful, transparent, and dependable. I’m always listening though—if there’s a better way to phrase the messaging, layout, or paywall experience, I’d love to hear your ideas. You can reach me anytime at support! Thanks again for giving Rhythm Generator a go. I hope you enjoy your practice, with or without the advanced features. 😊 Joe
