# Wikipedia vs ERG for iOS

The clearest difference is review sentiment: ERG for iOS at 100% against Wikipedia's 55%. ERG for iOS also leads on rating (4.8 vs 4.3) and iOS requirement (12.0 vs 17.6). Wikipedia's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (6.4K vs 65). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ERG for iOS holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Wikipedia has 6.4K ratings behind it against 65, so its average is the more settled of the two. Written reviews point the same way: 55% of Wikipedia's written reviews are positive against 100% of ERG for iOS's.

Wikipedia ships an update fortnightly, ERG for iOS every 4 months. Both last shipped on October 24, 2026.
