After building the CoachDesk desktop web app with Lovable, I wanted to explore what a mobile companion would look like ~ focused purely on the one thing a PT needs on their phone: knowing who needs attention right now.
I wrote a detailed design brief and fed it to Google Stitch to generate the mobile UI concept.
**Prompt**
The output
A 5-screen mobile concept covering a design system, splash screen, renewal alerts home, full client roster, and client detail sheet with a direct WhatsApp action.
It wasn’t bad for a concept. But it didn’t pick up the design language of the desktop version at all ~ different type treatment, different component feel, different visual weight. Nothing I’d hand to a developer.
Stitch is useful for getting ideas on screen fast. Not ready for production UI.
