BECOME A MUSICAL GENIUS, NO EXPERIENCE REQUIRED. Free | www.polyjamer.com The world probably doesn’t need another music app, but it definitely needs Polyjamer. At least people like yours truly, who have absolutely no musical training, need it. This app helps anyone create music either on their own or with friends and family. The app employs the power of artificial intelligence and a new algorithm to turn anyone into a rock star. And it’s super easy to use — choose your favourite genre of music, then move your fingers (up to four if you’re dextrous enough) around the screen of the four tabs, choosing percussions, bass, chords and melodies. That’s it, you’re creating music! Add more beats or melodies if you need, mute any if you want to experiment, delete — everything with just a single tap. Change notes or speed of the tune by swiping up and down or left and right, respectively, then save your creation when you’re happy with it. Want to start a band? Up to 20 devices can use the app simultaneously when connected over the same Wi-Fi network for a jam session. Just make sure everyone is not more than a couple of metres away from each other. If you’re a first-timer when it comes to creating music, there are tutorials in the menu to take your music to a crescendo.
