Verdict

The call

The clearest difference is in-app purchases: 4Studies at none against RevisApp's 16. 4Studies also leads on update cadence (every 2 days vs every 6 days). RevisApp's advantage is rating (4.5 vs 4.0) and ratings volume (17 vs 1). On price, ads, device support and iOS requirement there is nothing between them.
