Ghostpin

A desktop iOS location simulator used by more than 300 developers and testers working on GPS-based iPhone applications.

softwareGhostpinCase study
01

The problem

Location-based iPhone apps are awkward to test when every scenario would otherwise require physically moving.

02

What I built

I built a desktop tool that lets developers simulate locations, then handled packaging, distribution, product decisions, and support as it grew past 300 users.

03

What I learned

Shipping exposed the gap between code that works locally and a product that other people can understand, install, and rely on.

04

What’s next

Document the current workflow, the feedback that changed the product, and the path from first release to sustained use.
