Speeding up app to be more like Facebook Messenger?

I’ve made progress with my app that helps people with addiction, but a critical user issue is speed of use.

A user commented that “it should look and feel more like Facebook Messenger” and be slick like a native app.

I am willing to pay another qualified Bubble developer to help with a solution, since I’m approaching the limits of what I know how to develop with Bubble.

Please let me know if you are interested and I can provide more information.
