# Vivoo vs Sequent OXYGO

The clearest difference is rating: Vivoo at 4.9 against Sequent OXYGO's 4.3. Vivoo also leads on ratings volume (3.4K vs 64). Sequent OXYGO's advantage is in-app purchases (none vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Vivoo sells 2 in-app purchases, starting at $5.99 per month. Sequent OXYGO asks for nothing beyond the download.

Vivoo holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: Vivoo has 3.4K ratings behind it against 64, so its average is the more settled of the two. Written reviews complicate that: 58% of Vivoo's written reviews are positive against 65% of Sequent OXYGO's, so the app with the better star average is not the one people write more warmly about.

Vivoo ships an update fortnightly, Sequent OXYGO monthly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
