# e vs i

The clearest difference is rating: i at 4.0 against e's 2.1. i also leads on in-app purchases (none vs 6) and iOS requirement (8.0 vs 14.0). e's advantage is ratings volume (16 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. e sells 6 one-off in-app purchases. i asks for nothing beyond the download.

i holds the better App Store score, 4.0 against 2.1. That said, the two scores are not equally well evidenced: e has 16 ratings behind it against 1, so its average is the more settled of the two.
