# Osmosis vs Attenteo

The clearest difference is in-app purchases: Attenteo at none against Osmosis's 14. Osmosis's advantage is ratings volume (3.9K vs 1) and update cadence (monthly vs every 3 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. Osmosis sells 12 in-app purchases, starting at $16.99 per month. Attenteo asks for nothing beyond the download.

Attenteo 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 1, so its average is the more settled of the two.

Osmosis ships an update monthly, Attenteo every 3 months. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
