# nTube vs Osmosis

The clearest difference is rating: Osmosis at 4.8 against nTube's 4.3. Osmosis also leads on update cadence (monthly vs every 20 months) and ratings volume (3.9K vs 4). nTube's advantage is in-app purchases (none vs 14) and review sentiment (60% vs 47%). On price, 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. nTube asks for nothing beyond the download.

Osmosis holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Osmosis has 3.9K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 60% of nTube's written reviews are positive against 47% of Osmosis's, so the app with the better star average is not the one people write more warmly about.

nTube ships an update every 20 months, Osmosis monthly. The most recent releases landed on October 23, 2026 and October 26, 2026 respectively.
