# Fitlytics vs Clarity

The clearest difference is review sentiment: Clarity at 100% against Fitlytics's 78%. Clarity also leads on rating (5.0 vs 4.7). Fitlytics's advantage is ratings volume (15 vs 1) and update cadence (every 5 days vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fitlytics sells 23 in-app purchases, starting at $0.99 per month and Clarity sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Clarity holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Fitlytics has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 78% of Fitlytics's written reviews are positive against 100% of Clarity's.

Fitlytics ships an update every 5 days, Clarity every 2 weeks. The most recent releases landed on August 25, 2026 and September 11, 2026 respectively.
