Verdict
The clearest difference is ratings volume: Flykitt at 242 against JetShift's 1. Flykitt also leads on update cadence (weekly vs fortnightly). JetShift's advantage is rating (5.0 vs 4.8) and iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and monetization model 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. Flykitt sells 4 in-app purchases, starting at $4.99 per month and JetShift sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
JetShift holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Flykitt has 242 ratings behind it against 1, so its average is the more settled of the two.
Flykitt ships an update weekly, JetShift fortnightly. The most recent releases landed on September 27, 2026 and June 2, 2026 respectively.
