Verdict

The call

The clearest difference is rating: Unbordered Foreign Friend App at 4.7 against Casted's 3.0. Unbordered Foreign Friend App also leads on ratings volume (10K vs 4). Casted's advantage is ads (none vs shown) and update cadence (every 3 days vs fortnightly). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

ReceptionRating · Positive reviews · Number of ratings

Unbordered Foreign Friend App holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Unbordered Foreign Friend App has 10K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 43% of Unbordered Foreign Friend App's written reviews are positive against 50% of Casted's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Unbordered Foreign Friend App ships an update fortnightly, Casted every 3 days. The most recent releases landed on November 4, 2026 and November 2, 2026 respectively.
