How To Sync Data From Specific App(s) Across Multiple Devices
Now you're a bit vague when you say data but if I know what you're talking about then I would consider an app called OneNote by Microsoft. 


You need to have a Microsoft account. Go to Outlook and sign up for an email there. You don't have to use that email. It just links all the Microsoft apps together. 
Once you have created the email, download OneNote, both on your computer and all your other devices. Sign in with the email that you have created. 

It will give you plenty of features in which you can sync all your information that you need across all of your devices. For example, I have it on my phone and when I take a picture it is uploaded to OneNote and I can automatically see it on my computer. 

It will also sync all sorts of information and data that you need such as important documents like word Excel and PowerPoint and even video. 


There are also a few other apps that can do the same thing.
