Verdict

The call

The clearest difference is review sentiment: Proll at 100% against PrepGo's 23%. Proll also leads on monetization model (free vs free with in-app purchases) and rating (4.6 vs 4.3). PrepGo's advantage is update cadence (every 9 days vs every 2 months) and ratings volume (315 vs 14). On price, ads, in-app purchases and device support there is nothing between them.
