I have created one homesteading related Android App, Eggspense. This app helps track expenses associated with keeping chickens. It can graph the daily egg production of a flock of laying hens. It will also automatically calculate how much it costs to produce a dozen eggs. All you need to do is enter in how many eggs you collect each day along with your expenses.

Email Collection App

I have also created an app to collect email addresses from your Android device. This is helpful if you want to grow a mailing list at an event. You can display a background image on an Android tablet and store email addresses to the SD Card in CSV and vCard format.
