# Osmosis vs GCLEX

Osmosis and GCLEX both sit at 4.8 stars, but that hides the real split: 100% of GCLEX's written reviews are positive against 47% of Osmosis's. GCLEX also leads on update cadence (every 3 days vs monthly). Osmosis's advantage is ratings volume (3.9K vs 8) and chart position (#71 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Osmosis sells 10 in-app purchases, starting at $16.99 per month and GCLEX sells 4 in-app purchases, starting at $29.99 per month. Whichever you choose, the download price is not the number that matters.

GCLEX holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Osmosis has 3.9K ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 47% of Osmosis's written reviews are positive against 100% of GCLEX's.

Osmosis ships an update monthly, GCLEX every 3 days. The most recent releases landed on November 10, 2026 and November 6, 2026 respectively.
