Verdict

The call

The clearest difference is monetization model: StudyJourney at freemium against Opus One's subscription. StudyJourney also leads on rating (5.0 vs 4.7). Opus One's advantage is ratings volume (984 vs 1) and device support (4 vs 2). On price, ads and in-app purchases there is nothing between them.
