First prompt

Fais une app pour accorder mon violon, je mets mon La en hertz et le nombre de demi tons en plus, et elle montre les hertz de la nouvelle note

MeaningMake an app to tune my violin. I put in my A in hertz and the number of semitones to add, and it shows the hertz of the new note.

App name

Suggested features picked before building

Favorites, History

In the original recording, it took about 1 min 14 sec to build.

The app it made

• After clearing the app’s sample values of 440 and 0 and entering 442 and 3, it showed “Resulting note Do5 (C5) 525.63 Hz · A 442 Hz · +3 semitones” right away. The numbers are sample values for filming.
• Tapping “Save” added 1 entry to the “History.”

Change request

Ajoute une ligne avec la nouvelle note une octave plus bas

MeaningAdd a line with the new note one octave lower.

After the change

• A new line, “One octave lower · Do4 (C4) · 262.81 Hz,” appeared under the result.
• This calculation was saved to the history too.

In the original recording, the change took about 40 sec.

When reopened

Save, close, and open it again, and both calculations are still in the “History.”

Try writing it like this for a similar app

• Make an instrument tuning calculator. When I enter the reference A in Hz and the number of semitones to go up, show that note’s name and Hz.
• Let me switch the reference A between 440 and 442.
• Under the result, also show the frequencies one octave up and one octave down.

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.
