# EMBTuner vs E

The clearest difference is review sentiment: E at 100% against EMBTuner's 0%. E also leads on iOS requirement (11.0 vs 15.4). EMBTuner's advantage is rating (4.2 vs 3.5) and ratings volume (13 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

EMBTuner holds the better App Store score, 4.2 against 3.5. That said, the two scores are not equally well evidenced: EMBTuner has 13 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of EMBTuner's written reviews are positive against 100% of E's, so the app with the better star average is not the one people write more warmly about.

EMBTuner ships an update fortnightly, E every 3 weeks. Both last shipped on November 3, 2026.
