Excellent for relaxing, for supporting focus while reading or writing, for tuning out unwanted sounds and replacing them with something downright lovely. Looping is carefully designed and recordings are detailed and interesting. A broad range of available tracks from bright and active to calm and gentle. Updated review for new version: a few new free tracks included in this update, which is a nice fillip. The new interface has several usability improvements, looks nicer, and works smoothly. The app size is also noticeably smaller. For an app I use daily, these are all great to have. For new users, check out the new "suggested uses" section in the IAP catalog for some ideas about which tracks you might like best for different goals. I have some for winding down at night, some for cheering me up, some for feeling cozy... this app is an all-rounder!
