Verdict
The clearest difference is in-app purchases: CNS+ at none against Spine's 1. CNS+ also leads on update cadence (every 4 months vs every 26 months) and review sentiment (100% vs 75%). Spine's advantage is ratings volume (59 vs 4). On price, rating and ads 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. Spine sells 1 in-app purchase, starting at $1.99 per year. CNS+ asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.9 for Spine against 5.0 for CNS+. That said, the two scores are not equally well evidenced: Spine has 59 ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 75% of Spine's written reviews are positive against 100% of CNS+'s.
Spine ships an update every 26 months, CNS+ every 4 months. The most recent releases landed on October 22, 2026 and October 8, 2026 respectively.
