Verdict
The clearest difference is rating: iSmsee at 3.0 against SDFly's 2.3. iSmsee also leads on iOS requirement (8.0 vs 12.0). SDFly's advantage is update cadence (every 3 weeks vs every 4 months) and review sentiment (20% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
iSmsee holds the better App Store score, 3.0 against 2.3. That said, the two scores are not equally well evidenced: SDFly has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of iSmsee's written reviews are positive against 20% of SDFly's, so the app with the better star average is not the one people write more warmly about.
iSmsee ships an update every 4 months, SDFly every 3 weeks. The most recent releases landed on September 26, 2026 and September 22, 2026 respectively.
