●Garageband

With Garageband being free, ‘serious’ musicians might be sneery about its capabilities. But whether you’re a beginner or a pro looking to win your fifth Grammy, Apple’s app has got what it takes. It can act as a hub for other IOS music apps, its Alchemy synth alone used to cost a small fortune, and you get enough virtual stompboxes to make the most seasoned axe-thrasher giddy with glee. £free / IOS
