Make a gear ratio learning app with one sentence

First prompt

Erstelle eine Lernapp mit zwei Zahnrädern. Ich möchte das Antriebsrad mit dem Finger drehen und die Zähnezahl beider Räder ändern. Das zweite Rad soll passend mitdrehen. Zeige Drehrichtung und eine gut sichtbare Markierung je Rad.

MeaningMake a learning app with two gears. I want to turn the drive gear with my finger and change the number of teeth on both gears. The second gear should turn along with it to match. Show the direction of rotation and a clearly visible mark on each gear.

App name

Drehblick (Rotation View)

The app it made

• With the drive gear set to “12 teeth” and the driven gear to “24 teeth,” “Gear ratio 1 : 2” appeared in the middle.
• Turning the blue drive gear two full turns with a finger turned the large gear one turn in the opposite direction, and “Clockwise” and “Counterclockwise” were shown below.

Change request

Füge einen Schalter für ein Zwischenrad hinzu. Die Zähnezahlen der äusseren Räder bleiben gleich. Zeige, wie sich die Drehrichtung ändert, während ihr Drehzahlverhältnis gleich bleibt.

MeaningAdd a switch for an idler gear. The numbers of teeth on the outer gears stay the same. Show how the direction of rotation changes while their speed ratio stays the same.

After the change

• An “Idler gear” row and a “Hide idler gear” button appeared. When it’s on, a 12-tooth idler gear sits between the two gears.
• Now the drive gear and the driven gear both turn “Clockwise,” and the gear ratio is still “1 : 2.” The screen showed the explanation “2 meshing points: the direction of rotation is the same. The speed ratio stays the same.”

Try writing it like this for a similar app

• Make an app where I turn two gears with my finger. When I change the number of teeth, show the gear ratio.
• Show with arrows how the direction of rotation changes as I switch an idler gear on and off.
• Count how many turns I made on the drive gear and how many turns the driven gear made.

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.
