Verdict
The clearest difference is rating: CPU at 4.7 against PhoneScan's 4.0. CPU also leads on update cadence (fortnightly vs every 18 months). PhoneScan's advantage is ads (none vs shown) and iOS requirement (10.0 vs 15.6). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.
