# [solidcore] vs Ultrahuman

The clearest difference is in-app purchases: [solidcore] at none against Ultrahuman's 18. [solidcore] also leads on rating (4.9 vs 4.5) and ratings volume (29K vs 8K). Ultrahuman's advantage is update cadence (every 5 days vs every 6 weeks) and review sentiment (47% vs 21%). On price, ads, chart position and iOS requirement there is nothing between them.

Both are free to download. Ultrahuman sells 15 in-app purchases, starting at $2.90 per month. [solidcore] asks for nothing beyond the download.

[solidcore] holds the better App Store score, 4.9 against 4.5. Both are backed by a comparable volume of ratings — 29K and 8K respectively. Written reviews complicate that: 21% of [solidcore]'s written reviews are positive against 47% of Ultrahuman's, so the app with the better star average is not the one people write more warmly about.
