Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
