Verdict

The call

The clearest difference is price: Morse eMail at $0.99 against SDR's $44.99. Morse eMail also leads on rating (5.0 vs 4.6). SDR's advantage is review sentiment (85% vs 50%) and ratings volume (78 vs 1). On ads, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Morse eMail holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: SDR has 78 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Morse eMail's written reviews are positive against 85% of SDR's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Morse eMail ships an update every 3 months, SDR fortnightly. The most recent releases landed on November 11, 2026 and November 12, 2026 respectively.
