Verdict

The call

The clearest difference is rating: Safe NYU at 3.9 against ReTrader's 3.0. Safe NYU also leads on in-app purchases (none vs 10) and ratings volume (22 vs 2). ReTrader's advantage is update cadence (every 2 months vs every 9 months) and review sentiment (82% vs 71%). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Safe NYU holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Safe NYU has 22 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 82% of ReTrader's written reviews are positive against 71% of Safe NYU's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ReTrader ships an update every 2 months, Safe NYU every 9 months. The most recent releases landed on October 9, 2026 and October 24, 2026 respectively.
