Even better if CoolApp 1.0 has been continuously updated for new OS’s and the newest version isn’t compatible with a device stuck on an older OS, you can download the “last compatible version”. I was able to download and use Netflix, Crackle, Plex, Hulu, Spotify and Google Drive on my 2010 first gen iPad that was officially abandoned in 2012.

I reset it and downloaded older versions of apps last year.
