Verdict
The clearest difference is rating: E at 4.3 against Ped(z)'s 4.0. E also leads on iOS requirement (6.0 vs 11.0). Ped(z)'s advantage is review sentiment (85% vs 67%). On price, ratings volume, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
E holds the better App Store score, 4.3 against 4.0. Both are backed by a comparable volume of ratings — 3 and 3 respectively. Written reviews complicate that: 85% of Ped(z)'s written reviews are positive against 67% of E's, so the app with the better star average is not the one people write more warmly about.
