Verdict
The clearest difference is in-app purchases: [solidcore] at none against Ultrahuman's 10. [solidcore] also leads on rating (4.9 vs 4.5) and chart position (#142 vs unranked). Ultrahuman's advantage is update cadence (every 4 days vs every 6 weeks) and review sentiment (46% vs 21%). On price, ads, monetization model and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Ultrahuman sells 10 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 46% of Ultrahuman's, so the app with the better star average is not the one people write more warmly about.
[solidcore] ships an update every 6 weeks, Ultrahuman every 4 days. Both last shipped on November 6, 2026.
