Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Vypyr X holds the better App Store score, 2.7 against 2.2. Both are backed by a comparable volume of ratings — 9 and 12 respectively. Written reviews complicate that: 20% of Vypyr X's written reviews are positive against 25% of EFX Mobile's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 19, 2026 and October 17, 2026 respectively.
