Make an FM antenna length calculator app with one sentence

This example is from the Benin ad video. A radio repair shop owner in Cotonou, who cut rod antennas for FM reception for each customer and worked out the length for each frequency on scraps of cardboard, made an antenna length calculator app.

First prompt

Fais une appli pour mes antennes radio, je mets la frequence en MHz et elle donne la longueur du brin en cm, avec 7125 divise par la frequence

MeaningMake an app for my radio antennas. I put in the frequency in MHz, and it gives the rod length in cm, with 7125 divided by the frequency.

App name
Mon Antenne (My Antenna)
Suggested features picked before building
History, Favorites

In the original recording, it took about 1 min 16 sec to build.

The app it made

  • Entering 95 and calculating showed “Rod length 75.00 cm · 7125 ÷ 95 = 75.00 cm.”
  • Tapping “Add to favorites” kept 1 calculation in “History,” marked with a star.

Change request

Ajoute une ligne avec la longueur totale pour un dipole avec deux brins

MeaningAdd a line with the total length for a dipole with two rods.

After the change

  • A new line appeared under the result: “Full dipole · 2 rods 150.00 cm.”

In the original recording, the change took about 31 sec.

When reopened

Save, close, and open it again, and “History” still has 2 calculations.

Try writing it like this for a similar app

  • Make a calculator that tells me the half-wave antenna length in cm when I enter the frequency.
  • Save the stations I use often with their names and frequencies, and let me tap one to calculate right away.
  • Show the calculated length in inches too.

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.
