LEARN THE WHY Read short explanations that focus on the idea behind the answer. Full-question explanations appear as they are written and link to historical references when sources are available. Tap a source to explore further. BUILD A STUDY HABIT Your streak leads the Practice screen, so you can see today's progress and your next milestone. One answer counts toward your day.

Verdict

The call

The clearest difference is ads: apush.app at none against OnePrep's shown. apush.app also leads on rating (5.0 vs 4.7). OnePrep's advantage is ratings volume (750 vs 1) and iOS requirement (15.1 vs 17.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.
