He's fought coyotes
all his life.
Now he works
for you.

PREYR is the predator hunting system he built for the humans who can pull the trigger. A sound studio, the stand log with 4K photo and video, BRAIN™ himself, your AI hunting partner, and the CallTuneAI studio behind it. One app, built for the stand.

Building a sequence: sounds, order and gaps

Your calls, your order, your gaps. Process it and put it on your caller.

BRAIN
BRAIN chat

Ask him what works. He debriefs you, files it, and drafts the landowner update.

Stand log
Mission debrief

Hit DRT, Dead Right There. One tap marks any spot worth coming back to: a kill, a miss you want another try at, an animal you saw, tracks or sign, or a coyote that answered your locator howl. Drive straight back to it.

Photo and video
Photos and video filed by stand

4K photo and video from inside the log. Filed with the stand, texted to the landowner, or saved to your camera roll.

Transcript, hunter and BRAIN

He knows sounds. He gets to know you. Ask him about setups, gear, or how to bring one in when he hangs up at five hundred and will not clear the brush. Talk or type. He answers on the stand.

He does not stop at chat. A mile down the road he asks for the debrief, kill, miss, saw or mark, and files it with the stand. Ask him to write the landowner and he drafts the update with the photos and video attached. The more hunters run him, the smarter he gets. Your pins and your spots stay yours.

Hit DRT. He files the pin and the time, and the sound you ran is one tap from your library. A mile down the road he reminds you to file the debrief so neither of you forgets.

The studio

Build the stand here.
Run it on your caller.

Full stands to 20 minutes on the phone

Load your own calls. Put them in order with your own gaps and repeats, run it as long as the sit, then process it into one file that lasts the whole stand. Works with any caller. Need more than the phone does? Build it in the CallTuneAI Studio on the web, longer stands and heavier processing, and pull it straight back into PREYR.

Inside the log
4K photo and video

The camera lives inside the log. Shoot the dog, the setup or the tracks right from the stand you are on, and the photo or clip files with that pin instead of disappearing into 10,000 shots on your camera roll.

From there it goes wherever it needs to: text or email it to the landowner with BRAIN's update, share it, or save it to your camera roll. On a paid plan the originals are kept in your CallTuneAI library on the web.

Front and rearFlip mid-clip. No stopping.
Any huntRifle, bow, big game or varmints, turn off the call buttons and get the full screen, so zooming and tapping never set off a sound. Film with pre-roll. Running a remote caller? Just film.
Pre-rollLate on the button? Keep up to 30 seconds from before you hit record.
Big game

Not just for predators.

Deer, bowhunters
Stand and blind hunters

Pro Video works for deer season too. Mount the phone in the stand or the blind, on your rifle or bow. If he steps out before you get to the phone, take the shot and hit record after. Pre-roll goes back in time and captures up to 30 seconds before you hit the button and keeps rolling for the high-fives after it drops. You can even flip to selfie mode while recording for a seamless clip that captures everything.

Just the cameraThe whole screen is the camera, so you can zoom and record without anything else in the way.

"This is badass. BRAIN learns our stands! Like a new setup and a sidekick at the same time to bounce ideas off of. I'm diggin all of it."

"DRT navigation is spot on. I really like that it takes the guesswork out of remembering exact locations."
