# InBody vs Invoy+

The clearest difference is rating: Invoy+ at 5.0 against InBody's 4.0. InBody's advantage is ratings volume (1.9K vs 7) and chart position (#71 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Invoy+ holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: InBody has 1.9K ratings behind it against 7, so its average is the more settled of the two.

InBody ships an update weekly, Invoy+ fortnightly. The most recent releases landed on November 11, 2026 and October 31, 2026 respectively.
