NewsFlash is a program designed to complement an already existing web-based RSS reader account.
NewsFlash combines all the advantages of web-based services like syncing across all your devices with everything you expect from a modern desktop program: Desktop notifications, fast search and filtering, tagging, handy keyboard shortcuts, and having access to all your articles as long as you like.
