Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Bad Elf Flex holds the better App Store score, 3.6 against 2.0. That said, the two scores are not equally well evidenced: Bad Elf Flex has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of LoggerLink's written reviews are positive against 40% of Bad Elf Flex's, so the app with the better star average is not the one people write more warmly about.
LoggerLink ships an update every 4 months, Bad Elf Flex every 2 months. The most recent releases landed on October 2, 2026 and September 26, 2026 respectively.
