If you want to migrate from your existing YouTube Downloader app (4K Downloader, ByClick, YTD, Airy, Downie, WinX, Freemake, ClipGrab, whatever) because it's missing some features, dropped support for your OS, or simply became too expensive - you can write us a letter to get a fully-functional 1-month trial and do a comparison test without obligation.
P.S. Just send us some proof that you really bought this app and you're done.
P.P.S. We will also give you a 30% migration coupon code if you decide to stay.
