WhenDo vs AR Class
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
WhenDo
This tool provides a graphical programming environment for learning Arduino. It simplifies coding by allowing users to drag and combine blocks to create programs. The app supports wireless downloads to compatible Arduino devices and utilizes a cloud server for compilation.
- Graphical programming with drag-and-drop blocks
- Clear logic structure (When, Centre Node, Do blocks)
- Cloud server compilation
- Wireless BLE downloads
- Compatible with Bluetooth 4.0 Arduino chips

This is the most comprehensive graphical programming and developing tool based on Arduino. WhenDo is the most sufficient way to learn about Arduino and every basic programming logic. WhenDo is compatible with all the Arduino chips that have Bluetooth 4.0 module . Significant Features: 1. Graphical programming In this graphical programming language, user just need to drag condition and execute blocks and freely combine them. This development tool applies many amusing functions that the Arduino can accomplish in WhenDo. 2. Clear and meticulous logic Each sentence involves three elements: When block ( condition setting), Centre Node (combine When & Do block) and Do block ( execute setting ). Besides, the whole interactive User Interference environment is a big loop, which repeatedly run the program statements. 3. Cloud server compile Excellent file transfer and compile based on a Ubuntu server. Remote access to various libraries to improve its capability. 4. BLE download Wireless download the program through blueTooth 4.0 Arduino devices.
