# ISP vs SynoSync

The clearest difference is in-app purchases: ISP at none against SynoSync's 1. ISP also leads on iOS requirement (12.0 vs 16.4). On price, ads and device support there is nothing between them.

Both are free to download. SynoSync sells 1 one-off in-app purchase. ISP asks for nothing beyond the download.
