Below is an app that teaches the basics of DJing in a fun, interactive way without the need for expensive, specialist equipment. All you need is a phone or tablet and the free djay app (below) by Algoriddim. The Djay app guides you through every stage of mixing, teaching you the basics of decks and loops before giving you the freedom to mix and remix your library of music. Maybe you can create a playlist that could be used at a future party when lockdown is over!
