ArduinoDroid - Arduino/ESP8266

The app is a mobile application that allows users to write and edit code for AVR and ESP8266/ESP32 microcontrollers. It takes up about 500Mb of internal storage and cannot be installed on an SD card due to Android security policies. It is important to ensure that there is enough free space on the device before downloading the app.

The app has various features such as onboarding, the ability to open and edit sketches for Arduino and ESP8266/ESP32, and includes example sketches and libraries. It also has code syntax highlighting with theme support, code completion, real-time diagnostics for errors and warnings, and a file navigator. Additionally, there is a built-in software keyboard for convenience.

The app allows users to compile sketches without requiring root access and upload them over USB for various boards such as ESP8266, ESP32, and Arduino Uno/Uno_r3, among others. It also supports WiFi uploads for ESP8266/ESP32 boards. There is a serial monitor for debugging and the app can be used offline without an internet connection. It also has integration with Dropbox and Google Drive for easy file management.

The app has a modern material design and is regularly updated with new features and bug fixes. Users can also visit the app's blog and troubleshooting page for any issues they may encounter. There are also advanced paid features available for review, such as code completion and real-time diagnostics. The app is not an official Arduino team application, but rather a 3rd-party app developed and supported by an independent developer. The app is not affiliated with the official Arduino team, but it offers the same functionality and is optimized for mobile use.
