PiHelper is a free iPhone app developed by 茜 沙 that allows users to connect and manage their Raspberry Pi or Linux machine with ease. With PiHelper, users can monitor real-time CPU, memory, disk usage, processes, and temperature statistics.

The app also provides a colorful pinout for GPIO, allowing users to tap and change GPIO mode and output. Additionally, PiHelper offers an SSH Terminal that provides a real-time shell experience with full xterm capabilities.

PiHelper further includes an SFTP/File browser feature that enables users to browse files and directories, as well as easily upload, download, rename, and delete files. Users can also reboot or halt the server with a single tap, and custom commands are supported.

The app supports multiple languages, including English, 中文, 日本語, Русский, Deutsche, Français, and Lietuvis.
