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 also working on a full version for the Mac, very much a work in progress. Account Tracker and Meter Readings have also been ported to the Windows Phone platform. I have no plans to support Android or Windows!
I welcome feedback on any of my apps, so please get in touch!
