Verdict
The clearest difference is monetization model: Arbiter at free against Exam Study Planner's free with in-app purchases. Arbiter also leads on ratings volume (16 vs 4). Exam Study Planner's advantage is update cadence (every 5 days vs fortnightly) and iOS requirement (15.1 vs 18.4). On price, rating, review sentiment and ads there is nothing between them.
