Verdict
The clearest difference is update cadence: Test Doctor at every 4 days against ACT ® Math Prep's every 8 months. Test Doctor also leads on rating (5.0 vs 4.8) and iOS requirement (11.4 vs 13.0). ACT ® Math Prep's advantage is ratings volume (138 vs 6). On price, ads, in-app purchases and monetization model there is nothing between them.
