CREATE GUI THE EASY WAY: Use any embedded device (based on Arduino, STM32, PIC, Raspberry PI, etc.) to create flexible, high-end graphical user interfaces. Simple protocol allows you to control devices over WiFi, Mobile network, Bluetooth (LE) or USB.
Use our live designer tool to quickly build a GUI and simply add the initialization commands to your project.

No sign-up required!

Supports:
❋ Bluetooth devices
❋ Bluetooth LE devices
❋ IoT devices (MQTT)
❋ Ethernet devices (TCP/IP)
❋ USB devices

Create fully functional widgets with short commands:
* Toggle switch: |TG UID:tg X:50 Y:50\r\n
* Slider: |SL UID:sl X:50 Y:50\r\n
* and much more...

Simply customize widgets to your preferences.

❋ One app to rule them all

Use commercial boards such as Arduino, ESP32, ESP8266, Raspberry PI, STM32 Nucleo or any other microcontroller device to create stunning graphical user interfaces on Android. Control devices and change interfaces on the fly.

❋ Like a pro

Combine highly customizable widgets such as toggles, sliders, dials, charts and many more. Import images, videos and audio data from online resources. Check our manual and try it yourself!

❋ Easy to use, easier to modify

Simple protocol and default widgets enable quick deployment. Want more? Use advanced customization for truly professional and tailored appearance.

❋ IoT ready

Connect multiple devices and take control from anywhere, anytime! Secure IoT server provided by default - no additional configuration required! Or simply migrate to a custom MQTT broker and even setup your own.

❋ Seamlessly interact with Android sensors

Take advantage of the built-in hardware that Android device offers – interact with GPS, NFC, real-time clock, accelerometer, gyroscope, compass and much more.
