Here are a few of the most interesting Signal statistics and facts I was able to dig up including user counts. As always, be sure to check back in the future as I will be updating this post as new and updated stats become available.

What is Signal?
Millions of people use Signal every day for free and instantaneous communication anywhere in the world. Send and receive high-fidelity messages, participate in HD voice/video calls, and explore a growing set of new features that help you stay connected. Signal’s advanced privacy-preserving technology is always enabled, so you can focus on sharing the moments that matter with the people who matter to you. (source)
Please note that some of these numbers are easier to find than others. A few of these Signal statistics come from their own reports, but some are based on news reports and not official company tallies. No information contained on DMR should be relied upon to make investment decisions. Basically, this is the best I can find and I don’t guarantee anything to be 100%.
