Good but a few glaring issues
This app gets sounds a lot better than other apps do as far as fans go, however there are some issues. One of them being that there isnt a continuous function. Another is lack of variety. Theres only 3 fan sounds, theres way more sounds than that. The final and most important issue is that these sounds do not smoothly loop. The loops are abrupt and can be distracting if you are someone with a hard time sleeping.
