# C vs Zeno Connect

The clearest difference is in-app purchases: Zeno Connect at none against C's 11. Zeno Connect also leads on iOS requirement (13.0 vs 15.1). C's advantage is ratings volume (2.3K vs 4) and update cadence (every 6 weeks vs every 8 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. C sells 10 in-app purchases, starting at $1.99 per month. Zeno Connect asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for C against 4.5 for Zeno Connect. That said, the two scores are not equally well evidenced: C has 2.3K ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 51% of C's written reviews are positive against 33% of Zeno Connect's.

C ships an update every 6 weeks, Zeno Connect every 8 months. The most recent releases landed on October 2, 2026 and September 30, 2026 respectively.
