# ZYM vs GC

The clearest difference is ads: ZYM at none against GC's shown. ZYM also leads on monetization model (free vs free with in-app purchases). GC's advantage is device support (3 vs 1) and ratings volume (28 vs 9). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. ZYM sells 2 in-app purchases, starting at $9.99 per month and GC sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for ZYM against 5.0 for GC. Both are backed by a comparable volume of ratings — 9 and 28 respectively. Written reviews split almost evenly too, at 100% and 100% positive.

ZYM ships an update every 5 days, GC every 3 days. Both last shipped on October 31, 2026.
