Works OK.
The iOS app is great. The desktop app does its job OK, but leaves a lot to be desired, performance-wise. It crashes somewhat frequently, and lags a lot when trying to scroll through pages. Search is also slow and sometimes freezes the app, requiring a force quit. iCloud sync works well. This app has a lot of potential but lacks polish.
