The interface is beautiful!

Just curious... Did you implement each app natively? I.e. Swift and Kotlin? Or were you able to use a cross platform framework like Flutter?

It uses https://capacitorjs.com/ and I'm super happy with this choice. I think it feels fast simply because solving simple algebra problems is very light work these days (and of course its all on device... so no waiting on the network).
