# Imprint vs Cortex Flex Performance

The clearest difference is review sentiment: Cortex Flex Performance at 100% against Imprint's 38%. Cortex Flex Performance also leads on monetization model (free with in-app purchases vs subscription) and ads (none vs shown). Imprint's advantage is ratings volume (58K vs 10) and update cadence (every 5 days vs every 2 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Imprint sells 14 in-app purchases, starting at $3.99 per month and Cortex Flex Performance sells 1 in-app purchase, starting at $29.99 per month. Whichever you choose, the download price is not the number that matters.

Cortex Flex Performance holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Imprint has 58K ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 38% of Imprint's written reviews are positive against 100% of Cortex Flex Performance's.

Imprint ships an update every 5 days, Cortex Flex Performance every 2 weeks. The most recent releases landed on October 13, 2026 and October 10, 2026 respectively.
