The app is really slow. Checking my pin, opening the lock screen. Starting up the camera etc. App version 5.5.3 (35) Device: iPhone 5s with iOS 12.2

Same. I use the app almost every day, and recently the app became considerably slower. Slowness is so bad that I distract my audience a few seconds while the app struggles, during demo's.

5.5.2 (30) - iPhone 7, iOS 12.2

rebuild with flutter. thats the problem. your crossing too many process boundaries and using CoreJS

Flutter also has FFI. So you can call golang direct . Huge perf increases.

Google Dart FFI.

Then you take any golang code and compile it as a c shared lib. Then you can call it dite t from flutter.

You can even do this with video conferencing. Flutter provides a gltexture that is 100% GPU and a shared buffer you can access from golang.

It's early days a dart FFI just landed we use gomobile for flutter intensively and with dart FFI are changing over to using that for performance and easy developer experience

Sorry for the late response. We are working towards a new version of the app that should be considerably faster, but in the mean time there is little we can do to improve the situation.
