Tired of emailing yourself stuff? I give you AppBeam:

Push based content sharing between Android and Windows devices made easy, fast and secure. Designed not to leave a trace. Ad-free, no strings attached.

Uses Microsoft account validation for security and an isolated folder in your personal OneDrive account for temporary storage. This cache is immediately cleared on reception on the other device. (and so: it requires a Microsoft account)

Supported inputs (Windows AND Android):
- Clipboard
- Another App via Share contract
