Make a chord transposer app with one sentence

First prompt

Hazme una app: escribo los acordes de un tema y los semitonos que quiero subir, y me da los acordes nuevos.

MeaningMake me an app: I write the chords of a song and the semitones I want to go up, and it gives me the new chords.

App name

Mi Tono (My Key)

Suggested features picked before building

Save, Fingerings

In the original recording, it took about 1 min 6 sec to build.

The app it made

• Entering “C F G” in the chord field showed “New chords D G A · Transposed 2 semitones” with the default of 2 semitones. But the text in the field was dark and barely visible.
• Saving the song as “Cumple” added “Cumple · +2 semitones · D G A” to “Saved.”

Change request

Pon al lado de cada acorde su nombre en Do Re Mi, y que lo que escribo se vea claro.

MeaningPut each chord’s Do Re Mi name next to it, and make what I type easy to see.

After the change

• The text in the input field changed to bold white.
• After entering “C F G” again, a new line appeared under “D G A”: “D Re major · G Sol major · A La major.”

In the original recording, the change took about 47 sec.

When reopened

Save, close, and open it again, and “Cumple · D G A” is still in “Saved.”

Try writing it like this for a similar app

• Enter guitar chords and the number of semitones to go up, then tell me the new chords and which fret to put the capo on.
• When I write chords, show the Do Re Mi names next to them.
• Save the original key and the new key for each song, and show them in a list.

These are sample prompts, not real cases. What you get depends on what you ask for.

How to make it

1. Type the app you want in one sentence in the box on the home screen.
2. Answer “Give your app a name.” with the name you want.
3. From the features BYVE AI suggests, pick only the ones you want.
4. Tap “Build for 1 token” to build the app, then tap “Open app” to use it right away.
5. Write what you want to change in the chat, and the same app gets updated. A change also uses 1 token.

Good to know

• Each new app or change uses 1 token. You get 2 tokens when you first install, and you can get up to 3 more every 24 hours by watching ads. There are no in-app purchases.
• The apps you make and what you enter are saved on your phone, and apps you’ve already made open without internet. Features that fetch outside information, like weather and maps, need internet.
• It works on Android 8.0 or later and iOS 17.0 or later, and there’s no sign-up.
