Verdict

The call

The clearest difference is in-app purchases: Flight Test X20 at none against Comms's 12. Flight Test X20 also leads on review sentiment (60% vs 36%). Comms's advantage is update cadence (every 4 days vs every 5 weeks) and rating (4.2 vs 3.9). On price, ratings volume, ads and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Comms holds the better App Store score, 4.2 against 3.9. Both are backed by a comparable volume of ratings — 95 and 207 respectively. Written reviews complicate that: 60% of Flight Test X20's written reviews are positive against 36% of Comms's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Flight Test X20 ships an update every 5 weeks, Comms every 4 days. The most recent releases landed on October 20, 2026 and October 19, 2026 respectively.
