How can we help?

Pupwave is a free dog whistle and training app for iPhone and Android. It lets you play tones from 200 Hz up to 22,000 Hz, find the one your dog reacts to, and save it as a one-tap button. It also includes a clicker and other training sounds.

Open Find Tone while your dog is calm and nearby. Start at a low volume and play a short burst of 1 to 2 seconds. Watch for a head tilt, perked ears or a glance toward the phone. If you see nothing, move the frequency up or down and try again, one tone at a time.

Try the different sound styles too. Some dogs ignore a smooth tone but notice a pulse or a sweep. When you find a winner, tap Save for my dog.

Yes. Pupwave is free to download and use, with small ads. Pupwave Pro is an optional one-time upgrade that removes ads and lets you share sounds with family.

Yes. Tones, saved buttons and training sounds all work offline. You need a connection only to load ads in the free version and to share sounds with someone else.

No app can promise that, and we won't either. Pupwave works best as an attention cue: a sound that interrupts barking for a moment so you can redirect your dog and reward the quiet. Used consistently and paired with rewards, many owners find it helps.

If your dog barks from fear, anxiety or pain, please talk to your veterinarian or a certified trainer.

Pupwave is built to be gentle. Every tone stops on its own after 3 seconds, and phone speakers are far quieter than the devices sold as bark deterrents. Always start at a low volume, never hold the phone close to your dog's ears, and stop if your dog shows stress, such as a tucked tail, hiding, trembling or whining.

First, teach your dog that the click means a treat is coming. Click and immediately give a treat, 10 to 20 times in a row, over a couple of short sessions. After that, click the moment your dog does what you want, then reward. In the Training tab you can make the clicker, a whistle, a chime or another sound your main button.

Pupwave is designed for training your own dog. If a neighbor's dog is the problem, the best first step is a friendly conversation with the neighbor. Please don't use any sound to bother animals or people.

Some dogs simply aren't bothered by sounds, and older dogs often lose hearing in the high range. Try a mid range tone between 4,000 and 12,000 Hz, try the Pulse and Sweep styles, and make sure your phone case isn't covering the speaker. If nothing works, the training sounds in the Training tab paired with treats may suit your dog better.

Not quite, and no phone app is. Dogs can hear sounds well above 40,000 Hz, but phone speakers stop at roughly 20,000 to 22,000 Hz. Pupwave goes as high as your phone allows. Many adults can't hear tones above about 17,000 Hz, so the upper range is quiet to most people but still clear to dogs.

That's normal. Human hearing at high frequencies fades with age, so the top of Pupwave's range may be silent to you. Your dog can still hear it. If you want to confirm the sound is playing, start lower and slide up.

On iPhone, turn off Silent Mode and turn the volume up. Disconnect Bluetooth headphones or speakers. Make sure your case isn't blocking the speaker. Then restart the app.

Yes, but many speakers and headphones cut off very high frequencies. For tones above 15,000 Hz, your phone's own speaker usually works best.

After you find a tone, tap Save for my dog. Add your dog's name, a photo, a label like Quiet! and an optional note. To change anything later, open My Dogs and tap the pencil on that dog's card. You can change the photo, name, note, tone, sound style and volume.

Sharing is part of Pupwave Pro. Open My Dogs, tap the pencil, then tap Share with family and send the link by text or email. When they tap the link, Pupwave opens and adds the same button to their phone.

Pro removes all ads and lets you share sounds with family members, dog walkers or sitters. It's a one-time purchase, not a subscription.

Open Pupwave, tap the gear icon, then tap Restore Purchases. Make sure you're signed in with the same Apple ID or Google account you used to buy Pro.

Purchases are handled by Apple and Google, so refunds go through them. On iPhone, visit reportaproblem.apple.com. On Android, open your order history in the Google Play Store and request a refund there.

Your dogs' names, photos and notes stay on your phone, and we don't require an account. We collect anonymous usage data, such as which tones are played and saved, to improve Pupwave, and you can turn it off in Settings. The free version shows ads from Google AdMob, which may use device information to show and measure ads. We don't sell your personal information. You can read the details in our Privacy Policy.
