Verdict

The call

The clearest difference is rating: NX MobileAir at 2.5 against GR WORLD's 2.0. GR WORLD's advantage is in-app purchases (none vs 1) and update cadence (every 2 months vs every 3 months). On price, review sentiment, ratings volume and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

NX MobileAir holds the better App Store score, 2.5 against 2.0. Both are backed by a comparable volume of ratings — 28 and 75 respectively. Written reviews complicate that: 13% of NX MobileAir's written reviews are positive against 14% of GR WORLD's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

NX MobileAir ships an update every 3 months, GR WORLD every 2 months. The most recent releases landed on November 7, 2026 and November 4, 2026 respectively.
