Does anyone know of a todo-list app that can sync via USB between iOS and Mac? I've been looking for a todo-list app that can sync directly (via local/tethered USB) between my MacBook Pro (currently running Mavericks, upgrading soon to Yosemite) and iPod Touch 5 (running iOS 8). 

Apple's Reminders and Notes can only be synced via iCloud. 

Any suggestions? Thanks!
I've been looking for something similar, and it has proven quite difficult to find options. Everything's moving to the cloud.

Appigo's Todo app seems to allow local sync, but that may be limited to Wifi sync (with both devices on the same network). Still, even something like that (which at least does not involve a 3rd party server) is hard to find.

Omnifocus has a similar option that allows sync without a 3rd party server, but it requires you to run a webdav server on your mac (e.g. via server.app).

I'd love to hear of other options!
