Verdict

The call

The clearest difference is rating: E at 5.0 against Encyclopedia's 4.4. Encyclopedia's advantage is update cadence (weekly vs every 11 months) and ratings volume (15 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Encyclopedia sells 1 one-off in-app purchase and E sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

E holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Encyclopedia has 15 ratings behind it against 2, so its average is the more settled of the two.

UpkeepUpdate frequency
