Verdict

The call

The clearest difference is review sentiment: Screen Mirroring・Cast・Mirror at 61% against WI's 13%. Screen Mirroring・Cast・Mirror also leads on update cadence (weekly vs every 4 months) and ratings volume (28K vs 1). WI's advantage is rating (5.0 vs 4.4) and in-app purchases (none vs 11). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

WI holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Screen Mirroring・Cast・Mirror has 28K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 13% of WI's written reviews are positive against 61% of Screen Mirroring・Cast・Mirror's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

WI ships an update every 4 months, Screen Mirroring・Cast・Mirror weekly. The most recent releases landed on September 18, 2026 and September 24, 2026 respectively.
