First prompt
Mon vide-grenier : photo, nom, prix en euros et statut vendu pour chaque objet. Garde mes données.MeaningMy yard sale: photo, name, price in euros, and sold status for each item. Keep my data.
- App name
- Mon Vide-Grenier (My Yard Sale)
The app it made
- A screen appeared with an “Add item” section and the summary “Items 0 · For sale €0.00 · Received €0.00.”
- A lamp at €12, a bundle of 3 books at €6, and a small vase at €4 were added with photos. The item photos are images made for filming.
- The lamp sold for €10, but marking it as sold counted only the €12 entered at first.
Change request
Ajoute le prix de vente réel et le total encaissé. Garde mes objets et photos.MeaningAdd the actual sale price and the total received. Keep my items and photos.
After the change
- The first changed app didn’t properly add an actual sale price field to the items already entered, so one more fix was requested. The 3 items and their photos were still there.
- The lamp showed “Sold · Received €10.00 · -€2.00 vs. asking price,” and the book bundle showed “Received €6.00 · at the asking price.”
- The summary at the top became “Items 3 · For sale €4.00 · Received €16.00.”
Try writing it like this for a similar app
- Make a secondhand sales tracker app. For each item, save a photo, name, price, and whether it sold.
- Let me write the actual sale price separately, and show the total received at the top.
- Add a button to see only the items that haven’t sold yet.
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.
