Signal is a messaging app for simple private communication with friends.
Signal uses your phone's data connection (WiFi/3G/4G) to communicate securely, optionally supports plain SMS/MMS to function as a unified messenger, and can also encrypt the stored messages on your phone.
Currently available on the Play store and signal.org.
We use GitHub for bug tracking. Please search the existing issues for your bug and create a new one if the issue is not yet tracked!

If you're new to the Signal codebase, we recommend going through our issues and picking out a simple bug to fix (check the "easy" label in our issues) in order to get yourself familiar. Also please have a look at the CONTRIBUTING.md, that might answer some of your questions.
For larger changes and feature ideas, we ask that you propose it on the unofficial Community Forum for a high-level discussion with the wider community before implementation.
Have something you want to say about Open Whisper Systems projects or want to be part of the conversation? Get involved in the community forum.
This is based on code contributed by Samuel Welten (https://github.com/jukefoxer/Signal-Android) and Wollwolke (https://github.com/Wollwolke/Signal-Android/tree/feature/wa-db-import). Thank you both for this.
This fork of the Signal App provides a method to import one's WhatsApp conversations. It's currently still a pretty tedious process, but at least it's possible.
- Import 1-to-1 text conversation threads.
- Import group chat conversations if a group chat with the same name is set up in the Signal App.
- Importing images and videos messages from WhatsApp chats.
- Multimedia messages other than images and videos are currently not imported.
- It's pretty slow (10 seconds per 1000 messages).
- Extract your unencrypted msgstore.db from your WhatsApp installation. There are several methods to do so. WhatsAppDump seems to offer a possibility that doesn't require rooting the device. A more detailed description of how to do so might be added here in the future.
- Copy the msgstore.db file to the top level directory of your internal storage
- Make an encrypted Backup of your Signal Messages using the built-in feature of the Signal App.
- Build and install this version of the Signal App and import the encrypted Backup of your signal messages.
- You might have to go to the app permission settings and give it the permission to manage all of the external storage.
- Go to Backup => Import WhatsApp to start the import.
- Be patient until it finishes.
- If you're happy with the WhatsApp import create another encrypted backup of all Signal messages.
- Install the original Signal app again and import the encrypted Backup.
