Dcs want (I want them) to learn to play the guitar. They’ve both had lessons at school until lockdown and we’ve tried various things YouTube/fender free trial since. Ds1 has found yousician which he says he likes. He’s got the free app- we haven’t paid for the full subscription and it’s pricey. I would be happy to pay if it was good and worth it as ds1&2 would use it. Does anyone have experience (positive or negative)?
