What is Acornix?

Acornix is a free AI app builder for Android and a no-code app creator: an AI app generator that turns a sentence, your voice or a photo into a working app or game, right on your phone. You bring an API key from your favourite AI (Claude, GPT, Gemini or any OpenAI-compatible model), and Acornix does the rest:

• Creates apps and games from a sentence, your voice or a photo, and lets you keep improving them by asking. Out of ideas? The AI suggests original ones.
• Lets you show them off with a share card: your app, its name and how many seconds it took.
• Runs them like real apps: full screen, offline, on your home screen, each with its own private database.
• Acts as an assistant that can open apps, search YouTube, set alarms, blink the flashlight in Morse, read and change your apps' data and, if you allow it, tap and type inside other apps for you.
• Turns your phone or tablet into a desktop with AcornixOS: windows, a Dock and a Launchpad, like a little Mac in your pocket.

No terminal, no server, no account. Everything you create lives on your phone.

Acornix started as a Python tool for Termux. Version 2.0 is a full native Android app that does everything the old one did and much more. Looking for the Termux version?

✨ What you can do

🛠️ Create apps from text, voice or a photo

Type what you want, create it from your voice 🎙️ (voice to app, no typing needed) or attach a reference photo 📎 ("make an app like this"). Pick a type (game, utility, music…) or tap one of the ideas, and Acornix writes a complete, mobile-first web app live in front of you.

✨ Ideas from the AI. Out of ideas? Your AI suggests original things to build, from sound toys and generative art to science simulations and odd little tools, following the type you picked. Tap one and the full request and the name are filled in for you; tap 🎲 for a new batch. Ideas are cached, so they only cost a few tokens now and then, and you can turn them off in Settings.

When it's done you get an interactive preview, an Open button, an Add to home screen button and a suggested next improvement. Apply the suggestion or ask for your own changes ("add sound effects", "make the buttons bigger", "add a dark mode"). Every change is saved as a new version.

🎮 An AI game builder

Vibe coding a mobile game takes one sentence: "a platformer with endless levels", "a bowling game you play by swiping", "a castle defense with bosses and an upgrade shop". Acornix builds it with touch controls, keeps your saves and high scores in the game's own database, and you can keep asking for more levels, sounds or power-ups.

📣 Share what you made

Made something cool? Tap Share and Acornix builds a card with your app running big inside a phone, its name, how many seconds the AI took to build it and what you asked for. Edit or hide the request, play with the app until it looks just right, then post it on X, Reddit, WhatsApp or anywhere else.

🧬 Functionalities: apps that use your phone

Functionalities are apps that talk to your device through a built-in JavaScript bridge, window.Acornix. They can vibrate, switch the flashlight on, speak out loud, read the battery, send notifications, share, copy, open other apps and even ask the AI from inside the app. Some examples: a big SOS button, a battery dashboard, a pocket translator that speaks, a Pomodoro timer that vibrates.

🤖 An AI assistant that gets things done

One chat for everything. Ask in your own words and the assistant picks the right tools, showing every step it takes:

• "Create a piano and open it"
• "Turn on the flashlight in SOS" · "Set an alarm at 7:30" · "Start a 10 minute timer"
• "Search Nirvana videos on YouTube" · "Open Maps and find a pharmacy"
• "Add bread to my shopping list" · "What's my best score in Bowling?"
• "How much battery do I have?"

Total control (optional). Turn on the Acornix total control accessibility service and the assistant can also see the screen and tap, type and scroll inside other apps, for example "open Settings and turn on dark mode". It only acts while a task you asked for is running. It asks before sending, paying, calling or deleting anything, never sees password fields, and you can stop it at any time from the notification.

📱 Your apps, like real apps

All your creations live in My Apps, a launcher with live thumbnails, search and filters. Tap to open full screen; long-press for more:

• Improve with AI or edit the code by hand.
• Versions: every creation, improvement or edit is kept, and you can restore any of them.
• Add to home screen: a real icon that opens the app in its own window, like an installed app.
• Data: see, export or clear what the app saved.
• Share it as a ZIP, with or without your data, or rename and delete it.

🖥️ AcornixOS: your phone as a computer

Open AcornixOS from Tools and your apps become a desktop, inspired by macOS:

• Windows you can drag, resize, minimize and maximize, with the classic red, yellow and green buttons. Touch one and it comes to the front.
• A Dock with your favourite apps and the ones you have open. Long-press to add or remove.
• A Launchpad with all your apps and a search box.
• Wallpapers to choose from, and a menu bar with the time and battery.
• Apps open in a window; tap the green button (or double-tap the title) to make one full size. On a tablet you get several apps side by side, like a real computer.

Every window is the real app, with its own data, camera and files. Add AcornixOS to your home screen and it opens like any other app.

🗄️ A private database for every app

Every app gets its own fast SQLite database (Acornix.db), so a to-do list keeps its tasks and a game keeps its saves and high scores. The data:

• survives improvements, because the AI is told which collections and fields already exist;
• can be read and changed by the assistant ("add eggs to my to-do list");
• can travel inside the app's ZIP;
• is included in backups.

Each app runs on its own isolated origin, so apps never see each other's data.

<p align="center"> <img src="docs/screenshots/data.jpg" width="250" alt="The Data screen"> </p>

☁️ Backups and sharing

• Full backup: one ZIP with all your apps, their versions, data and files. Save it to Google Drive or anywhere else from the system picker, and restore it on any phone.
• Android backup: your apps and data are also included in your Google account backup.
• Import ZIPs shared by friends, including apps made with the original Termux version of acornix.

📋 Manual studio: no API key needed

Don't have an API key? Copy a ready-made prompt, paste it into ChatGPT, Claude or Gemini on the web, then paste the answer back. Acornix checks the code, warns you if something is missing and installs the app.

🔔 Always up to date

Acornix checks GitHub for new versions. When one comes out you'll see what's new and can update with one tap, right from the app.

And more

Phone status (battery, memory, storage), Material You colors with light and dark themes, and an interface in English and Spanish. Generated apps follow your phone's language too.
