An amazing app! – ACT Mastery 2017 Prep Review

This app is awesome! It's completely free and very thorough. This is the best app I've tried so far for ACT prep and it's really helped so far. It not only provides good practice questions, but very accurate answer explanations for each question, and a myriad of topics and subtopics.
