Verdict

The call

The clearest difference is review sentiment: Tether Mobile at 100% against Screen Mirroring's 12%. Tether Mobile also leads on in-app purchases (none vs 7) and ads (none vs shown). Screen Mirroring's advantage is rating (4.5 vs 2.0) and ratings volume (53K vs 1). On price, update cadence, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Screen Mirroring holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: Screen Mirroring has 53K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Tether Mobile's written reviews are positive against 12% of Screen Mirroring's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Tether Mobile ships an update every 2 months, Screen Mirroring every 3 months. The most recent releases landed on November 2, 2026 and November 9, 2026 respectively.
