I use an iPhone and my fiancé uses Android. He is not very tech savvy. He does not like to text for privacy reasons. I was going to recommend we get Signal but see others in Lemmy talking about Matrix. Is that better? If so, what app is best that works on both our phones? Thanks Lemmy friends!
Likely for the sake of only needing a single app. Both SMS and Signal messages (as well as similar apps) all use your phone number for receiving messages so why not view all of them in a single app? SMS apps are nearly always lightweight so storage isn’t really an issue but for some, having one less icon on the app drawer is a plus.
