Edit: Oh yeah, DON'T USE SIGNAL. Use Matrix instead, offers the benefits of signal without the drawbacks of lack of sync and phone number requirements and is decentralized. The fact that everyone is going gaga for signal as "the BEST messaging app" should be a big red flag in and of itself, because hype trains like this aren't organic, just saying.
I use Signal a little. While it doesn't sync full history you still get all new messages going forward which is good enough for me.
