The latest Big Ted creation is finally out! I've been working on an iPhone client for FreeAgent (a UK-based SaaS accounting package which I use) for a few months - it would have been out a lot earlier, but I got a little side-tracked by London Bike App :)
The result is mobileAgent.
There is a load more information on the mobileAgent page, but the TL;DR version is:
Enter timeslips and mileage expenses on your iPhone, as you are on the move. Better yet, as you incur them! No more forgetting what you did, or trying to remember which days you worked at the end of the month.
Works online and offline, so you can do it on the tube (or in a high-altitude tube), and sync up when you have a signal.
Works on iPhone and iPod Touch.
Coming in the next version, which is mostly coded and tested is:
A timer, so you can start a task, and then log it with the elapsed time
A odometer tracker, so you can enter the start odometer value, drive somewhere, enter the end odometer value, and log it as a mileage expense.
It's available in the AppStore now. I will most likely post a more technical post-mortem later, with some of the things I learned from the development, later.
