Bear Horn
Turn your phone into a loud bear-deterrent horn for hikes
Bear Horn turns your iPhone into a loud bear-deterrent horn for hikes and campsites — no separate gadget to buy or charge, just your phone at full volume. 10 sound types: hiking bells, a barking dog, a wolf howl, human conversation, a campfire, and more. Random intervals avoid a robotic loop. Fully offline. No account, no data collected. One-time purchase, no subscription. Also on Android as "Mountain Bell."
Hi Product Hunt,
I'm a solo developer from Japan. Bear sightings near hiking trails (and even in towns) have been a growing problem here over the past couple of years, and the usual advice is "carry a bell" — but a $10 bell is one more thing to buy, attach, and remember to bring.
So I built Bear Horn to turn the phone you're already carrying into that bell. Tap once, and it plays a loud warning sound through your speaker on a random interval, so it doesn't sound like a looping recording. I recorded 10 different sound types — hiking bells, a dog barking, a wolf howl, human conversation, a campfire crackling — because wildlife tends to avoid signs of human presence more reliably than a single repetitive tone.
A few things I focused on:
- Fully offline. No signal on the trail, no problem — it's just local audio playback.
- No account, no data collected. I don't want your hike to also be a data-collection event.
- One-time purchase. No subscription, no ads, no premium tier — everything is included.
- A flashlight toggle, because trailheads at dawn are dark and you often only have one hand free.
It's also on Android as "Mountain Bell" — different name for historical reasons, same app.
I'd love to hear from anyone who hikes or spends time outdoors: what would make you actually trust an app like this over a physical bell, and what would make you not?
