The better the quality of your head phone is, the better your score will be.
This app has been made for musicians, but it can be enjoyed by non-musicians as well. Most people will recognize the sound of an instrument. But will you recognize 3 different instruments that play simultaneously? Or even 5 instruments? The combinations are not entirely picked at random. Subtle differences make it hard to avoid making mistakes.
This app is free and Ad-Free. Recognize Music Instruments 1 has been designed for smartphone, but it will work on a tablet as well. Android 4.1.1 and up!
