In the old days when I traveled, I used my Palm III to track my expenses as I traveled. Since there was no expense tracker available, I wrote one. I wrote it for my N810 running Chinook. I haven't verified if it will work on Diablo.

With the Expense Assistant, you can add/edit/delete expenses. Each expense has a category (Chicago Trip, London Trip,...), type (dinner, lunch), currency symbol, cost and date.

Expenses can be sorted by any column. They can also be filtered by category, so you can see what the current trip is costing.

I am having trouble getting it into the extras repository. It is not open source (but it is free to use). Seems the tools are all geared toward open source, and if you don't release the source, the tools don't work well.

I have created an entry at maemo.org in the downloads section - search for expense.

I welcome your feedback. This is version 1.0. I tried to make it finger friendly, but I'm still trying to figure out how to make the scroll bars wider in Gtk.
