# Fluo vs Lexium

The clearest difference is update cadence: Fluo at every 4 days against Lexium's every 6 weeks. Fluo also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.6). Lexium's advantage is ratings volume (12 vs 2). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Fluo sells 2 in-app purchases, starting at $9.99 per month and Lexium sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Fluo against 4.9 for Lexium. That said, the two scores are not equally well evidenced: Lexium has 12 ratings behind it against 2, so its average is the more settled of the two.

Fluo ships an update every 4 days, Lexium every 6 weeks. The most recent releases landed on October 14, 2026 and October 31, 2026 respectively.
