I'm curious about the stack-- is the app React Native with some actual native modules, then? Or is it based on something like Ionic?
I did it because I don't have the time to maintain for 3 platforms in parallel without one falling behind and I'm not a fan of React native personally. I spent a good chunk of time testing with much older hardware as a target to make sure performance wouldn't be a noticeable distraction for users and I'm happy with how it turned out :)
