Verdict
The clearest difference is review sentiment: Paystro at 100% against Grey's 38%. Paystro also leads on monetization model (free vs free with in-app purchases) and iOS requirement (15.0 vs 17.6). Grey's advantage is update cadence (every 3 days vs fortnightly). On price, ads, in-app purchases and device support there is nothing between them.
