Make a telescope magnification calculator app with one sentence

This example is from the Dominica ad video. Someone in the hills near Roseau who looks at the stars through a telescope every weekend made an app to calculate the magnification, which they used to divide out in their head every time they changed eyepieces.

First prompt

Make an app for my telescope, I put the telescope focal length and the eyepiece focal length in mm, and it shows the magnification

App name: Star Zoom
Suggested features picked before building: Eyepiece Set, Formula Help

In the original recording, it took about 1 min 30 sec to build.

The app it made

With 1000 for the telescope and 25 for the eyepiece, it showed “Magnification 40×” right away.
In “Manage set,” the name “Plossl” and a focal length of 25 were entered, and tapping “Add to set” showed “Your eyepieces 1 saved · Plossl.”

Change request

Add a line with the magnification with a 2 times Barlow lens

After the change

A “With a 2× Barlow lens: 80×” line appeared under 40×.
The saved Plossl 25 mm also shows in the quick picks at the bottom.

In the original recording, the change took about 56 sec.

When reopened

Save, close, and open it again, and the 1 saved eyepiece, Plossl, is still there.

Try writing it like this for a similar app

Make a telescope magnification calculator. When I enter the focal lengths of the telescope and the eyepiece, show the magnification.
Save the eyepieces I own, and change the magnification when I tap each one.
When I enter the magnification I want, work backward to the eyepiece focal length I need.

These are sample prompts, not real cases. What you get depends on what you ask for.

How to make it

Type the app you want in one sentence in the box on the home screen.
Answer “Give your app a name.” with the name you want.
From the features BYVE AI suggests, pick only the ones you want.
Tap “Build for 1 token” to build the app, then tap “Open app” to use it right away.
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.
