This is something we’ve been investigating since the app’s inception and we continue to investigate constantly. Syncing is a very difficult problem to solve, especially in regards to handwritten notes which can be combined with images and text. I don’t have any kind of ETA for when syncing will be supported, but rest assured this is a high priority for us. We appreciate all your feedback on this idea.KimBoo York commented
I have a Surface Pro 4 tablet and a Samsung Galaxy 5 phone, I really really need syncing across devices!
