Take7 Free, with in-app purchases

Using your device’s microphone to listen to you play, Take7 gives you a score based on how many notes you’ve played right (or not) when you practise your instrument. The app then selects ‘loops’ of the music for you to practise in isolation at a slower tempo, before gradually speeding you back up. Setting a daily goal of 10 minutes practice – what most teachers would suggest as a minimum – the app also keeps track of how many days in a row you keep up an unbroken streak, and what your longest streak is. Though some sheet music is available for free, additional scores can be bought from an online store, including graded collections (though they don’t match any exam board curriculum). While no app can replace a teacher, Take7 is an enjoyable, useful and well-designed tool. If you’re looking for something to help you structure your practice, this could be it. Elinor Cooper
