OTOH I find the Marine Band Crossover (with a bamboo comb) to be probably the best bending harp out there due to it receiving detailed factory setup.

> Lower notes are generally easier to bend than higher notes

Additionally, you'll probably find a lower key harp to bend better, at least to a point. I feel like an A harp is the sweet spot for bending really well without being so low that it starts becoming difficult. G harps are good too, but require you to dig deeper to get a good bend.

One thing to note (pun intended) is that you can only bend the higher of the two notes in a hole. On the lower half of the harmonica, those are the draw notes. But the upper octave switches these around. The blow notes are the higher ones there, and those are the ones you can bend.

Actually, you've inspired a related idea I’ve been thinking about: since the app already shows a magnified pitch view for each target note, I could track how accurately each target is hit — not over time, but per note. That means collecting cent-deviation stats every time a target pitch is active.

For example, if you’re working on bending hole 3 draw down to F#, the app could keep track of: - how many times that target was attempted, - your average deviation (in cents), - and your best attempt so far.

It’s not a full frequency-vs-time graph, but it's very focused feedback — and could motivate practice in a very concrete way. I’d love to make this part of a future version. Thanks again for the spark!

The app seems neat, but focused on precision in bending. Precision in bends doesn't matter a ton for most styles. It's more about feel. Build and resolve tension. Don't worry too much about hitting things exactly. That advice will eventually fail you if you go into styles that need a more complete scale, but for blues/rock/country, it's much more about intuition than precision. The best way to learn is to play along with a lot of things and build "feel" instead of trying to precisely hit notes. (though you do need to hit a clean note to start bending)

I absolutely agree: bending is a deeply organic thing that you need to feel and hear in your body. No app can replace that. The goal of my app is not to teach you how to bend, but to help you understand what you're actually playing — especially for beginners who are unsure whether their bend reached the target pitch.

It’s more like a "mirror" than a teacher: you still have to do the work with your ears, but the app can help confirm (or challenge) what you think you hear. Some folks find that helpful in the early stages.

Also — yes to Gindick and Jason Ricci! Two amazing resources. I hope my app can complement, not replace, that kind of learning journey.

Thanks again for the thoughtful input!

Yes, the email listed on the Imprint page is the best way to reach me — I’d love to hear your suggestions when you get a chance.

And it’s great that you brought up Melody Maker tuning! Even though I don’t currently own a harp in that tuning, I’ve implemented theoretical support for Melody Maker (as well as other Richter variants) in the app already. So users can visualize bends and pitches correctly even when playing in those alternate tunings.

Your Stevie Nicks example is such a beautiful use case. Expressive bending like that — starting just below the pitch and sliding up — is exactly the kind of thing I hope the app can help people hear and understand more consciously.

Also, I really appreciate that you mentioned manual retuning. Let’s Bend was designed to be lightweight and offline, so it’s ideal for checking pitch quickly when tuning by ear or file. That’s one of the practical scenarios I had in mind from the start.

Thanks again — I’m learning a lot from your comment.

Let’s Bend was originally designed to support harmonica bending practice, but the idea of using the "stay in the square" feedback as a pitch visualizer for other instruments is incredibly exciting. It’s great to see it working in real musical contexts!

Just to address your points:

There’s already a *“Keep screen on”* toggle in the app settings – enabling it should prevent Android from turning off the screen during use.

You can also *change the root key and tuning system* in the settings. While the interface is still harmonica-focused, this makes the app more flexible – including for lower pitches like a violin's low G.

I’m genuinely grateful for your feedback and enthusiasm – and thanks for trying the app in such a creative way!
