Make a surf app that works out swell speed from the wave period

First prompt

Fais une appli pour le surf, je mets le temps entre deux vagues en secondes, et elle donne la vitesse de la houle, 1,56 fois le temps en m par seconde, puis en km par heure

MeaningMake an app for surfing. I enter the time between two waves in seconds, and it gives the swell speed: 1.56 times the time in m per second, then in km per hour.

App name

Ma Houle (My Swell)

Suggested features picked before building

History, Decimal places

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

The app it made

• With 12 seconds between waves, “Estimated swell speed 67.4 km/h · 18.7 m/s” appeared right away. The numbers on screen are samples for filming.
• Tapping “Add to history” added 1 entry to the history.

Change request

Ajoute une ligne avec la distance entre deux vagues en m

MeaningAdd a line with the distance between two waves in m.

After the change

• In the changed app, a new line appeared: “Distance between two waves 224.6 m.”
• This calculation was saved too, bringing the history to 2 entries.

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

When reopened

Save, close, and open it again, and the 2 history entries are still there.

Try writing it like this for a similar app

• When I enter the wave period in seconds, show the swell speed in km/h and m/s.
• Save the date and the beach name to the history too.
• Show results to only one decimal place.

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.
