First prompt

In the original recording, it took about 1 min 13 sec to build.

The app it made

• Entering a length of 30 cm and a weight of 350 g and tapping “Save catch” showed “The catch has been saved.”
• “30 cm · Weight 350 g · K 1.296” appeared in the list right away. That’s 350 g divided by 30 cm cubed, times 100.

Change request

Skriv en rad med vikten vid 40 cm med samma K

MeaningWrite a line with the weight at 40 cm with the same K.

After the change

• A new line appeared in the list entry: “At 40 cm, same K: 829.63 g.”
• Then a second fish, 40 cm and 830 g, was saved.

In the original recording, the change took about 33 sec.

When reopened

Save, close, and open it again, and the 2 fish are still in the list.

Try writing it like this for a similar app

• When I enter a fish’s length and weight, calculate the condition factor and save it by species.
• Sort fish of the same species by condition factor, highest first.
• Let me write down the date and the name of the place for each catch 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.
