Web/Chrome/Firefox/iOS/Android: If you want a simple cloud-based clipboard that syncs notes across different devices, then Belt.io gets the job done without much fuss.
Sign up for the webapp, get the Chrome or Firefox extensions, and download it across your iOS or Android devices. Once you have it set up on all these, you can copy-paste any text or links into individual notes, which are instantly synced across the app. It works just as it says and even gives you a notification when there’s an update.
What I didn’t like about the app was its sharing feature, which lets you share your notes only with other Belt.io users. There’s no reason a simple text note can’t be shared on other platforms like email, text messaging or IM. But hey, it’s still a neat app apart from that, especially since it’s free!
