NatureNotes is an app for recording anything you do, at any time, then sharing your doings with friends.

It’s premise is that you are going on a “walk” or maybe “hike” or just browsing through a museum or gallery. You can record text, photos, or audio. Your location for every observation is automatically recorded so that later you can re-visit when and where you saw things.

BarrelCalc is a unique calculation app for estimating the amount of fluid in a barrel. The idea for the app was made by someone who works in the wine industry, complaining there was no easy way to figure out how much wine was left in the barrel by standard measurements.

However, it’s more than a calculator: It’s also a database program, allowing you to store and keep track of content within any number of barrels you wish. You can assign an ID to each barrel, and record information about each one.
