You may not realize it, but on Android, Signal acts very similar to iMessages, pulling in your SMS & MMS so that you can seamlessly text regardless whether the other person is using Signal or not. Most features that come with the Android build just don't exist in Signal for iOS, or are delayed by a year, like Giphy support: https://signal.org/blog/signal-and-giphy-update/

Additionally, if someone is so petty as to consider not using iMessage as a dealbreaker, they likely have other issues that would cause a significant relationship to fail. More than a few families have one Apple user ID for 3+ phones, which makes iMessage effectively break (unless you want mom & dad to see Johnny's messages!).
