The Signal messenger and protocol.
Thank you very much. Those links were not very exposed by the website...
Aurora store is another option. You can download Aurora store on F-Droid if you want to give it a try.
If there is on fdroid it is not authentic, make sure to see if it comes from a trusted source as signal does not put it on f-droid themselves, possibly leaving the door open to scams!
I edited my comment to clarify. Aurora store can be downloaded from F-Droid
It's not on F-droid. Also, pfffff as if i would use the Aurora store when i can use any other method
I meant Aurora store is available on F-Droid

You do you. I don't use Signal so I'm not sure if using GitHub would mean you need to revisit the page and download a new APK whenever you want to update. Aurora could simplify that a bit.
