croc-app

croc-app is an Android client for croc with a modern, mobile-first UI built in Kotlin and Jetpack Compose.

It is designed to make file and text sharing feel much more natural on Android: quick send, quick receive, QR-assisted flows, saved codes, transfer history, and better handling for the small details that matter on phones.

Why this project exists?

This project was inspired by croc-gui, which showed that a mobile-friendly croc experience could work.

But croc-gui is older, written in Go, and lacks a number of features and UX improvements we wanted in a modern Android app. croc-app is our attempt to build a more polished, more maintainable, and more feature-complete Android experience around croc.

Features:

- Quick send and quick receive flows

- Send files or clipboard text

- QR code generation for fast pairing

- QR scanning for receive

- Saved send and receive codes

- Transfer history and favorites

- Android share-sheet support

- Received files published to Downloads/croc-received

- Material 3 UI designed specifically for Android
