I can't work for a longer time without instrumental background music. Also, my wife hated me until I started applying the Pomodoro technique, which means 25 minutes of focused work and a 5 minute break, repeatedly. I use the breaks to do chores, so when I end my work day, the chores are also all done! Happy wife, happy life. I can only recommend the Pomodoro technique! And this app implements it perfectly. Additionally, it integrates with Apple Music in case you're subscribed. If you are, you get the benefit of select playlists for focused work to choose from, depending on your mood. Some of these playlists I crafted myself, like the Pokémon themed one. Try it out, the music is so beautiful and calms me down every time! It's so underestimated.
