Build, ship, and earn — unleash the full potential of ZBerry Uno with ZScript and the official SDK.

Meet ZScript — the language of ZBerry

Designed from the ground up for the ZBerry ecosystem, ZScript combines clean, readable syntax with powerful low-level control. Write expressive code that runs efficiently on the calculator's hardware.

// Hello, ZBerry!
func onStart() {
   let display = UI.getScreen();
   display.drawText("ZScript is live", 10, 20);
   if (input.keyPress(KEY_MENU)) {
     stealthMode.activate();
   }
}

✅ Easy to learn, hard to outgrow — ideal for both indie devs and pros. ZScript supports first-class functions, event-driven I/O, and a rich standard library for cryptography, graphics, and system integration.

The .zapp revolution

Say goodbye to messy asset folders and dependency headaches. The .zapp format is a single, self-contained bundle that holds everything your project needs: scripts, sprites, sound samples, level data, configuration, and even encrypted user preferences.

One file. Zero clutter.
When you build a game or tool for ZBerry, the SDK packs all your resources into a compact .zapp file. The ZBerry OS reads everything directly, with built-in integrity checks and fast decompression — ready for submission to ZStore.

Build → Test → Publish

While developing, use the built‑in ZBerry emulator to preview your app instantly. For real‑hardware testing, push builds wirelessly to your device without cables. Once you're ready to share your creation, submit the .zapp file for review. Every app published on ZStore goes through a quality and safety check — protecting users while ensuring a professional storefront.

Write once, run everywhere

ZScript abstracts hardware differences across ZBerry models. Your app works on ZBerry Uno, Pro, and future devices without modifications.

Professional results, minimal effort

High-level constructs like `UI.buildMenu()` and `crypto.encrypt()` let you create sophisticated stealth tools with just a few lines.

Wireless dev builds

During development, push .zapp files directly to your connected ZBerry over Wi‑Fi — instant iteration without cables.

Review & launch on ZStore

Submit your final .zapp package via the developer dashboard. After passing our review process, your app appears in ZStore for millions of users.
