VerbSquirt is a conjugation app for mobile devices that uses multiple choice questions and matching activities to test your knowledge. You can learn by verb group, verb tense, or build your own custom exercises. It also has a summary page that allows you to see how many points you score on average per day, week, and month.
The app doesn’t have a very attractive interface compared to other resources, but if you want to tap on answers to practice recognition rather than active recall, VerbSquirt may be a good option for you. However, you may want to use Conjuguemos instead — it provides free exercises that require you to use active recall and type out the answers. You can also try SpanishDict or Ella Verbs if you are learning Spanish.
