This is my favorite tones app. I especially like the business and camo tones. My dog is a bit nutty and freaks out from the sound of most alert tones. Ive been able to find a few in this app that dont bother her. I work from home so the camo ones that sound like office noises are great. Would love to see even more variety of business camo tones and maybe ones that blend in with other environments such as sounds from around the house. The chimes, bells, and high-pitches tones really bother my dog so would like to see more lower-pitched tones as well. Thanks for a great app!
