KuDoo French app for iPhone and iPad

I found this to be the best way to learn and test verb conjugations so I built an app for it. Contains over 500 of the most commonly used verbs with 11 verb tenses and 4 moods. The default quiz settings are a good starting point for new language learners as it tests the 20 most common verbs on present indicative. The app is completely free with the option to donate. With donations I would like to add quiz history and integrate game center to incite learning through competition, and possible a noun memorization section. Thanks for your support. Feedback and suggestions welcome!
