About Zerynth App

The Zerynth App is a ready to use mobile app that acts as an interface for all the Zerynth powered objects. Turn any mobile into the controller and display for smart objects and IoT systems. No need for Android or iOS code.

- Automatically discover all the Zerynth devices available on the local network
- Enable a bidirectional communication channel between the Zerynth script and the App
- HTML 5 templates are edited directly in Zerynth Studio and embedded in the bytecode


Zerynth provides an easy to use, professional and performant development suite for the cross-platform and high level design of interactive objects, artistic installations, and internet/cloud connected devices.

The Zerynth App is a ready to use mobile app that acts as an interface for all the Viper powered objects. It needs to be installed on a smartphone or tablet and it will become the interface of all the network or bluetooth powered Zerynth objects.
Interactive objects or artistic installations, but also controlled IOT devices need a proper interface. Simple character LCDs and buttons are useful but nowadays considered obsolete. Rather a device with a mobile interface is more and more appreciated. That is the reason why a ready to use App has been integrated into the Viper suite.
When launched the Viper App gives the user the possibility to discover all the Viper devices available on the local network (whatever it is: Wifi or Bluetooth). Once one of them will be selected the App will become its interface.

Zerynth is an open source, powerful, easy and affordable way to develop innovative devices and applications based on the ARM Cortex 32-bit micro-controllers (like Arduino Due, ST Nucleo F401RE, UDOO, Particle Core, Particle Photon and many other professional and prototyping boards) combined with other state-of-the-art sensors and actuators, and expansion boards. It enables fast prototyping with bleeding-edge boards and components that can quickly be transformed into final designs. Programming examples and reference designs for many applications are provided and they help designers to make the transition from prototype to final product even smoother.

The Zerynth App interfaces are based on HTML 5 templates that can be written directly in the IDE and transferred to the microcontroller flash together with bytecode. The App includes many famous Javascript libraries that can be included and used from the template. All the logic of interaction between the Zerynth object and the Zerynth App is written in Python, while the UI is specified in HTML and Javascript; this way it is possible to build mobile controlled objects without writing any Android code.

Any data collected or generated by Zerynth powered devices (i.e. room temperature, room light and sound level, etc.) can be shown on mobile by sending a notification from Python to the App. The communication also happens the other way round with the App sending events to the Python script which in turn can execute functions. Therefore the App can also work as a remote controller, by specifying in the Python script which event triggers a specific callback (e.g. a switch button in the App can turn a led on and off).
