croc-app

Modern client for croc, easily and securely send files and text
New in version 4.1.0
Changes Made:

1. Dark/Light mode sensitive Splash Screen
2. Upgrade croc to v10.4.3
3. Version Bump
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

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
