Have you ever encountered a serious challenge with a hobby you love?

This was the exact situation one of our Natively users faced.

Meet Mika.

His dearest hobby is playing the tenor saxophone.

But Mika was never that strong with theory, which became a challenge during rehearsals and jam sessions.

For example, when someone in band practice would shout, “Next play will be in B minor,” he’d have to quickly figure out what the correct key was. This was especially hard for songs he didn’t know from before.

Mika wanted an app that could instantly turn concert keys into the notes tenor saxophonists actually play, while showing the right scales.

He looked for an app that could solve his problem, but wasn’t able to find anything to help him transpose.

Mika also didn’t have any background in coding and didn’t want to spend huge amounts of money hiring a developer.

This is exactly why he created Transpose Assistant using Natively.

So, what exactly was his process?

Mika started by using ChatGPT to craft precise prompts for Natively’s AI, which then generated the app code.

He then used a ChatGPT agent to run real user flows, catch wrong notes and edge cases, and fix any UI issues.

Finally, he asked ChatGPT to write targeted fix-prompts that Natively applied to quickly patch any problems.

Mika used AI for the app icon, store copy, privacy page, pricing/VAT setup, Play Console hurdles, and even the support email/domain.

Now, you might be wondering:

“But how did Mika get his app published on Google Play?”

Good question!

Google Play requires you to run an open testing period with 20 users for 14 days. Reaching out to online communities makes it easy to arrange testing and quick feedback.

The incredible takeaway from Mika’s story is how prompting makes it easy to create an amazing app that gets published on a major app store.

Transpose Assistant has received awesome feedback and is proving useful in rehearsals and jam sessions.

Although he mainly made the app for himself, he likes the fact that others are finding it very useful and getting value from it. Especially people who don’t have a strong background in musical theory. After sharing it in a couple of online communities, he quickly found testers who gave positive feedback.

Mika now plans to use Natively to create an app in the healthcare space, after being inspired by his daughter, who works in the sector.

Leveling up his understanding of AI for software development has opened up an entire new passion for Mika, and he loves pairing human intent with AI prompting.

“It felt like having an extra pair of expert hands throughout the build cycle,” says Mika.

There are so many amazing niches that lack dedicated apps that solve specific problems. You can create real value for communities by following a simple process. This can kickstart your journey toward a thriving app business or a rewarding hobby app.

We’re excited to follow Mika’s progress. And if you’re reading this, we can’t wait to hear about the incredible app you build!
