# Base64 Encoder Decoder vs OpenEML

The clearest difference is review sentiment: OpenEML at 100% against Base64 Encoder Decoder's 50%. OpenEML also leads on update cadence (every 6 days vs every 5 months) and ratings volume (22 vs 3). Base64 Encoder Decoder's advantage is in-app purchases (none vs 4) and rating (5.0 vs 4.7). On price, ads and device support there is nothing between them.

Both are free to download. OpenEML sells 4 in-app purchases, starting at $1.99 per 7 days. Base64 Encoder Decoder asks for nothing beyond the download.

Base64 Encoder Decoder holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: OpenEML has 22 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of Base64 Encoder Decoder's written reviews are positive against 100% of OpenEML's, so the app with the better star average is not the one people write more warmly about.

Base64 Encoder Decoder ships an update every 5 months, OpenEML every 6 days. The most recent releases landed on June 2, 2026 and September 22, 2026 respectively.
