As my Twitter profile says, I am an iOS developer, Munro Bagger, Climber, Mountain Biker, Runner and occasional Orienteer.
All of my original apps were written because I wanted to do things on my own device that I was previously doing in spreadsheets or by other means. Account Tracker helps you track your finances across multiple accounts, Hill Lists provides data for a number of UK hill lists, and Meter Readings helps you monitor your energy usage and spending. Man 3 is just a customised version of Meter Readings for building professionals.
I have since adapted them all to work on the iPad, the iPhone 5 and the new iPod Touch. I also provide regular updates to add features and fix bugs. More recently Account Tracker and Meter Readings have been ported to work on Windows Phone.
I welcome feedback on any of my apps, so please get in touch!
