I am an iOS and Mac developer, hill walker (Munroist #5670), fell runner and climber.
All of my apps were written because I wanted to do things on my own iPhone that I was previously doing in spreadsheets or by other means.
I provide regular updates to add features and fix bugs. Account Tracker now has a companion Mac app, ATB Viewer, and I am working on a full version for the Mac, albeit very slowly. Account Tracker and Meter Readings were also ported to the Windows Phone platform, but these are no longer supported.
I welcome feedback on any of my apps, so please get in touch!
