Verdict
The clearest difference is review sentiment: SkyDrone at 100% against Gem Stack's 35%. Gem Stack's advantage is rating (4.6 vs 2.5) and ratings volume (36K vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Gem Stack sells 1 one-off in-app purchase and SkyDrone sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Gem Stack holds the better App Store score, 4.6 against 2.5. That said, the two scores are not equally well evidenced: Gem Stack has 36K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 35% of Gem Stack's written reviews are positive against 100% of SkyDrone's, so the app with the better star average is not the one people write more warmly about.
Gem Stack ships an update weekly, SkyDrone every 2 weeks. The most recent releases landed on October 10, 2026 and October 5, 2026 respectively.
