# LoggerLink vs Bad Elf Flex

The clearest difference is rating: Bad Elf Flex at 3.6 against LoggerLink's 2.0. Bad Elf Flex also leads on ratings volume (14 vs 1) and update cadence (every 2 months vs every 4 months). LoggerLink's advantage is review sentiment (67% vs 40%) and iOS requirement (12.0 vs 15.5). On price, ads, in-app purchases and monetization model there is nothing between them.

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 October 12, 2026 respectively.
