Vibe Coding an Android App

A friend of mine told me that there was a new, temporarily free AI that was good for coding and we should use it to create something. I decided to create an Android app I had in mind to find my car and other locations. I called it GPS Points.

On Friday, August 21st, 2026, my friend said in a group chat that the day before, a new anonymous model had appeared that seemed to be very powerful and free for a week. The model was called Ox Alpha and they gave 100 trillion tokens for free over the course of a week. All I had to do was create an account on OpenRouter and use the model for whatever I wanted.

I wrote a detailed prompt specifying what I wanted: the language to use (Kotlin), the platform, what I had installed, the phone I had, what the app should and shouldn’t do, the colors I wanted, and I even mentioned the Haversine formula to calculate distances, but maybe it would have figured it out by itself. In the end, I forgot to give it a name, but it didn’t matter; the AI decided to call it GPS Points. I was fine with that name, but instead of calling the package com.example.gpspoints, I decided to call it net.misello.gpspoints and proceeded to create the subdomain gpspoints.misello.net on my server. I configured NGINX to redirect it to the proper folder in my projects.

The AI worked for almost 13 minutes, spent 42,202 tokens (for free), and structured the answer into 8 sections. It generated about 1,500 lines of code in 11 files and explained where to place them and how to create them. Obviously, it didn’t work on the first try, but after fixing a few errors, it worked pretty well. I also added a logo (generated with Gemini AI):

The app is very simple. It just consists of a list of locations (ten at most). You can add your current location to the list with a name. Then, you can navigate to it. If you don’t have an internet connection, you can navigate with an arrow that indicates the distance and direction. Alternatively, if you are connected to the internet, you can simply use Google Maps to navigate to it. What I wanted was an easy and simple way to find where I parked my car.

Finally, I added a landing page in my projects section so anyone can install the binary. I don’t plan to add it to the Play Store for now, so you will need to allow third-party software to be installed on your phone if you want to try it.

Ah, I almost forgot! After the free week passed, the Ox Alpha AI model was revealed to actually be ZAI GLM-5.3-Flash from the Chinese labs Z.ai, running on Chinese chips. I personally preferred the name Ox Alpha.
