# Fit vs SonarMD

The clearest difference is monetization model: SonarMD at free against Fit's paid. SonarMD also leads on rating (5.0 vs 4.6). Fit's advantage is update cadence (every 4 days vs every 5 weeks) and ratings volume (70 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

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

SonarMD holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Fit has 70 ratings behind it against 1, so its average is the more settled of the two.

Fit ships an update every 4 days, SonarMD every 5 weeks. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
