# My Koi vs Sync

The clearest difference is update cadence: Sync at every 5 weeks against My Koi's every 3 months. Sync also leads on price ($1.99 vs $2.99) and iOS requirement (12.0 vs 15.6). My Koi's advantage is ratings volume (218 vs 23). On rating, review sentiment, ads and in-app purchases there is nothing between them.

My Koi costs $2.99 and Sync $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 4.9 for My Koi against 4.7 for Sync.

Written reviews split almost evenly too, at 95% and 95% positive.

My Koi ships an update every 3 months, Sync every 5 weeks. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
