Verdict
The clearest difference is ads: Shadow at none against Cell to Singularity's shown. Shadow also leads on review sentiment (100% vs 82%) and iOS requirement (12.0 vs 15.0). Cell to Singularity's advantage is ratings volume (23K vs 69) and update cadence (fortnightly vs every 6 weeks). On price, rating, in-app purchases and monetization model 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. Shadow sells 11 one-off in-app purchases and Cell to Singularity sells 17 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for Shadow against 4.8 for Cell to Singularity. That said, the two scores are not equally well evidenced: Cell to Singularity has 23K ratings behind it against 69, so its average is the more settled of the two. Written reviews are what separate them: 100% of Shadow's written reviews are positive against 82% of Cell to Singularity's.
Shadow ships an update every 6 weeks, Cell to Singularity fortnightly. The most recent releases landed on September 30, 2026 and October 15, 2026 respectively.
