I would like to introduce my first project, Quiz Bird Free:
play.google.com/store/apps/details?id=com.jivko.quizbirdfree
The game features:
- Numerous bird songs and calls for over 60 North American species
- Twelve different quiz games that challenge you to identify different groups of birds
- Ability to create, save and play your own quiz games by selecting specific birds that you want to learn
- Randomized nature of quiz generation that ensures almost unlimited replayability value
It is very relaxing, fun, and also an excellent exercise for the brain. Let me know what you think, whether you found it easy or difficult, or any other constructive comments you may have. I'll return the favor!
