Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
CSJ GPS holds the better App Store score, 3.7 against 3.3. That said, the two scores are not equally well evidenced: Deerc FPV has 257 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 34% of Deerc FPV's written reviews are positive against 27% of CSJ GPS's, so the app with the better star average is not the one people write more warmly about.
Deerc FPV ships an update fortnightly, CSJ GPS every 3 weeks. The most recent releases landed on October 14, 2026 and October 7, 2026 respectively.
