Found a nice freeware Google Android app site the other week. I've been testing a few from this site and found most to be very good. There are some that are for Android phones, most will tell you in the descriptions but some do not. There are also Lite versions which have limitations, much like demo apps so watch out for them as well but the majority are 100% freeware, complete full versions. It's a matter of trying them out.
You can find the site here http://www.freewarelovers.com/android
Some good apps and games to check out are;
Alchemy
Analog Clock Collection
Angry Birds Seasons
Andors Trail
Guts and Glory
Magic Doodle
Maple Paint
