Launched "Cadence: Guitar Theory" (https://cadenceguitar.com/) a guitar learning app with a focus on music theory in September.

Currently right above that $500/month when including lifetime purchases. Had a sizeable bump in October thanks to blowing up on here which also gave me an app store boost so thanks guys :)

I'm working on new lessons at the moment, after that I'll probably try to improve on the animations and sound effects to give the app more "juice", should be a fun thing to work on. Also still trying to figure out marketing and how to get visibility overall...

I'm no expert on this subject but I don't think this is how trademark law works.

If you type "Cadence" (or any other common name really) in a trademark database you will literally get hundreds of result from various countries and industries. I think as long as you're not offering a similar service or at least working on the same industry there is no way they would have a case against you.

Also there are actually quite a few apps which use the name Cadence already (a bike app, an event planning app, a running app...)

You're the third one to ask for it since this post so it will definitely be in the next update (in a week or so) as it should be quite easy to implement

Thank you!

It's one of those awful situations of "nobody does it, so nobody is going to do it".

Thanks, I hope you will like it!

Thank you for the feedback

There is supposed to be a short transition window when playing a new sound to prevent the popping issue. Is it on the "Note names" lesson recap? Also if you don't mind sharing your version of iPhone/iPad, I'm concerned some older devices might have performance issues since the audio is synthesized in real time, maybe increasing the window could help.

As for the audio being completely broken and needing an app restart it actually happened to me a couple times during development but I was never able to understand how or why it occured and haven't seen it again since months so no fix in sight...

iPhone 17 Pro Max (iOS 26.0.1)

I have reproduced the pops everywhere I am able to manually trigger notes.

I was fiddling with the guitar tones, then opened from the background when the audio broke. I tried repeating that, but no repro.

Thanks for the info, definitely not an older device then ;)

I'll see what I can do to fix that but can't reproduce at the moment I'm affraid (using iphone 12), maybe simulator will help. Will also add some better handling of audio when the app goes in the background as that might be what causes bug number 2.

Thanks :)

If by proposed practice you mean the tidy bits of guidelines at the end of some lessons, those are mostly just general tips for beginners more than a clear plan to follow.

I believe the value of the app is in learning how all those musical block work and interact together, how to recognize them by ear and visualize them on the neck so you can incorporate them in your playing rather than an app to learn the technicality of the guitar.

As for my own playing, as stated in another comment it has quite suffered from my lack of practice due to the time spent on making this...

Thanks !

Funny I've always found the technicality of the guitar to be the easier part on the contrary.

Don't get me wrong, playing a piece like this cleanly and with such feel takes great skill and is probably not something I will ever be able to do but I mean easy in the sense that you can quite clearly see the path to take to get there (or halfway there). "Just" learn the piece slowly block by block, then repeat it for hundreds of hours without much thinking until it flows by itself (I'm simplifying but you get my point).

On the other hand, while theory can be grasped quite fast, applying it to your playing, composing, and improvising with it has always felt to me like a multifaceted beast that you have absolutely no idea at which angle to tackle from. You just stumble your way around it until the pieces start clicking together and it's really hard to find a clear path to follow which makes it much harder imo, or at least more frustrating/blurry.

Gut feeling I suppose ? Pricing less felt like selling it short considering I still have quite a few features and content I want to add to the app, pricing more felt too much considering it's missing aforementioned features (:

I might bump the price to $50 in a year or so if I'm satisfied with the new content/features and feel like it deserves it (only for new users, lifetime owner will get all updates for free obviously).
