# e vs Radiacode

The clearest difference is rating: Radiacode at 4.2 against e's 3.0. Radiacode also leads on in-app purchases (none vs 3) and ratings volume (93 vs 2). e's advantage is iOS requirement (15.1 vs 17.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. e sells 3 in-app purchases, starting at $22.99 per 3 months. Radiacode asks for nothing beyond the download.

Radiacode holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Radiacode has 93 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of e's written reviews are positive against 63% of Radiacode's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 19, 2026 and October 14, 2026 respectively.
