I haven’t had a need to do any native mobile work yet, but I’ve often stumbled upon Kinetise and Thunkable in my searches. They both tick some of the boxes that are important to me in constructing mobile apps, but I don’t have any experience as of yet.
Another tool I’m currently playing around with is called Supernova Studio (supernova.io). It takes Sketch files and generates native iOS, Android, and React Native app code, but there isn’t yet a method of incorporating live data without coding. It’s supposed to come in future releases.
