Verdict
The clearest difference is price: Morse eMail at $0.99 against SDR's $44.99. Morse eMail also leads on rating (5.0 vs 4.5). SDR's advantage is review sentiment (84% vs 50%) and update cadence (every 2 weeks vs every 3 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

Morse eMail costs $0.99 and SDR $44.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Morse eMail holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: SDR has 64 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 84% of SDR's, so the app with the better star average is not the one people write more warmly about.
Morse eMail ships an update every 3 months, SDR every 2 weeks. The most recent releases landed on October 11, 2026 and October 20, 2026 respectively.
