Learnings and final designs
I took the MVP designs through multiple reviews at Zoom, then quickly addressed the feedback I received:
The entry point for "My QR code" was difficult to find below the fold, and users confused it with the "Scan QR Code" action.
I moved the entry point for "My QR Code" to the user profile card at the top of the screen where it was easier to find. I also changed the page to a bottom sheet to simplify navigation.
The tab switcher was hard to use with one hand.
This was changed to a single button and moved to the bottom of the screen where it was easier to tap.
The "My QR Code" view was cluttered with too much UI.
Unnecessary UI was eliminated to emphasize the most important information. Reset was changed to an explicit text button and placed next to Share.
