Sometimes it can be really difficult to find useful apps on the Android Market due to all of the spam, so we have compiled a short-list of 5 useful Android applications.

#1: Aquarium Pocket Guide (APG)

If you're a hobby or professional fish keeper, APG will be a perfect addition to your Android app installs. When you're out and about and spot a fish you would like to purchase, in cases where you know nothing about the particular species, you will go online and do a google search for the species, but 9 times out of 10, internet access is unavailable.

APG does not need internet access; you can do a quick search for the species or common name and find the information you need. It comes packed with over 600 species of freshwater, brackish, saltwater fish, plants and invertebrates.
