PureGym Switzerland removed live gym occupancy from its app in April 2025, while still advertising the feature on its website. I coded 100 App Store reviews and compared the app against competitors to work out what that cost members, then redesigned the flows around it. The result is a case for treating a removed feature as a retention problem rather than a UI one.

Car rental sites hide the real cost until checkout or the desk. Across five usability tests on six live rental sites, I mapped where people lost track of the price and the deposit, then redesigned the full booking flow for a fictional brand around one rule: the price you see is the price you pay, deposit included.

where users get stuck
01
Finding the problem
I go through a flow the way users do and document where they drop off, and why. The output is a prioritised list of what’s broken, with the reasoning behind each item.
02
Designing the fix
Rebuilt screens, prototypes, and specs developers can build from. Where it makes sense I build it myself in Framer, including custom React components when a design needs them.
