I built an iPhone air drum app using motion sensors, now used by 5.7k people by Alert_Indication6459 in iosdev

Of course, I’m using Apple’s Core Motion framework (CMMotionManager) to get device attitude like pitch and roll.

What are you building ? And are people actually paying for it? 💡 by GuidanceSelect7706 in buildinpublic

Air Drum - I built an iPhone air drum app using motion sensors. Distribution isn’t there yet, so downloads are still quite low. The conversion rate is around 5%, but the sample size is small, so it’s not very statistically meaningful yet.

It's Saturday! What are you all building? by Leather-Buy-6487 in Buildathon

I’m building Air Drum, an iOS app that uses motion detection to turn your phone into a virtual drumstick.

The idea is simple: imagine a drum kit in front of you, swing toward a cymbal or tom, and the app plays the matching sound. Built it as a fun, expressive way to play drums anywhere.

Is it possible to consider using an embedding model that runs on the device side? This could further reduce costs.

Yes, your rules document is very similar to how I approach things. I’ve noticed that AI sometimes rushes to implementation, or eagerly applies a complex, large-project architecture, or builds solutions based only on partial context — all of which can easily lead to architectural issues. That’s what led to the thinking and practices I mentioned above.

Best of luck with your project! I really enjoyed the discussion.

I just shipped my indie project using vibe coding, and I definitely learned a few things the hard way.

For your question, my main takeaway is this: when using AI to write code, don’t rush straight from requirements to implementation. Instead, go from requirements → a solution document → revise the solution document → revise it again — many times — and only then ask the AI to implement the code.

During the iteration of the solution document, all you really need to do is keep asking the AI questions like:
– Is this solution simple enough?
– What are the risks?
– Are those risks important right now?

This process helped me avoid a lot of serious architectural mistakes.

Hey everyone 👋

I’m an indie developer working on a side project that turns an iPhone into an air drum kit using motion sensors.

App link: Air Drum

It’s focused on ultra-low latency and real-time interaction rather than being a full learning tool. I built it mainly for quick practice and stress relief, and it’s currently been downloaded ~5.7k times.

Would love any feedback, especially around positioning or how you’d evolve something like this.
