Den: Calm Sounds for Dogs

Den is a calm companion for your dog - a pocketful of gentle sounds you play while you are together. Every program is generated live on your phone, not played from a recording, so each tone is steady and exact: a true heartbeat rhythm, a smooth low pulse, rain that never loops or jumps. 21 PROGRAMS, EIGHT FAMILIES - Heartbeat & Rhythm - steady rhythms like the ones puppies rest against - Frequency Tones - soft, sustained tones (432 Hz, 528 Hz and more) - Brainwave Entrainment - two slow tones a few Hz apart (headphones best) - Stressful Events - thunder, vet trips, travel, rescue recovery - Life Stage - puppy settle-down and deep, slow tones for senior dogs - Nature & Environment - rain, Schumann 7.83 Hz, earth tones - Music & Full Sessions - long calm pieces and a canine sound bath - Practice - quiet door knocks over a calm bed, raised gently over weeks PLAY IT YOUR WAY Choose 20, 30, 40 or 45 minutes, 1, 2 or 4 hours, or "until I stop it." Sound fades in over 3 seconds and eases out over 2 minutes, so endings never startle your dog. MADE FOR REAL LIFE - Plays with the screen locked, with controls on the lock screen - Pauses for phone calls and resumes with a gentle fade - Pauses when headphones are unplugged or Bluetooth drops - Dims itself at night so the room stays dark - Save a short note after each session and watch what settles your dog QUIET BY DESIGN No account. No sign-up. No ads. No notifications. No tracking. Den never connects to the internet - it works on a plane, in a cabin, anywhere. THE SCIENCE, IN PLAIN WORDS Every program includes a short note on the thinking behind it, with the research it draws on, written in plain language. Den is a comfort tool made for calm moments together. It is not veterinary care, and it does not replace your vet. One-time price. Everything included, forever.
