# OmniLogic vs Flex

The clearest difference is rating: OmniLogic at 4.7 against Flex's 3.0. OmniLogic also leads on ratings volume (8.8K vs 4) and update cadence (every 3 weeks vs every 6 weeks). Flex's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (9.3 vs 15.1). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

OmniLogic holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: OmniLogic has 8.8K ratings behind it against 4, so its average is the more settled of the two.

OmniLogic ships an update every 3 weeks, Flex every 6 weeks. The most recent releases landed on September 29, 2026 and June 1, 2026 respectively.
