// THE PROBLEM

Calling an elk is
like playing an
instrument. Without
a teacher.

You blow into your diaphragm in the truck. Watch every YouTube breakdown. Buy the Phelps, the Bugling Bull, the Native Jr. And still have no idea if you actually sound like an elk. You'll find out the moment you don't want to — when a 6x6 hangs up at 80 yards, deciding if you're worth the walk.

001

Your tone is off, but you can't hear it.

Dropping your jaw on a calf call? Going past the ringing tone on the location bugle? MtnWispr can tell you.

002

You can't hear yourself the way a bull does.

We've always wondered if we sound close enough to fool a bull. Now with MtnWispr you don't have to guess.

003

It's hard to know what's happening in your mouth.

Diaphragm calls are tricky to learn and bad habits are easy to pick up on. Inside the academy, 2x World Champion Joel Turner breaks down how to make each call and the common mistakes to avoid.

// HOW IT WORKS

A coach in your pocket. 365 days a year.

Get instant feedback on your calling year round and show up to the trail head ready. Practice when you actually have time, instead of cramming the week before opener.

// WHAT YOU GET

Everything that goes into making a bull stop.

Elk Biology & Situational Calling

Sound right isn't enough. The Academy teaches elk biology — rut phases, herd dynamics, bull temperament — and how to use that knowledge to decide what call to make and when to make it.

STRATEGY + MECHANICS

Technical Feedback

Pitch, tone, harmonic match, sustain, and spectral quality — all measured against a real bull. You get specific, plain-English notes on exactly what to fix.

SCORED ON 3 DIMENSIONS

Track The Off-Season

Watch your scores climb from June to August. See which calls you've nailed and which ones still need work. No more guessing if you actually got better since last year.

TIMELINE + DRILL HISTORY

World Champion Academy Instruction

Two-time World Champion Joel Turner breaks down his favorite calls into micro steps inside the Academy, so you can build from a solid foundation and master each call.

Bulls Called In
Per Season

You may have seen Joel on The Joe Rogan Experience talking about shot control. What most hunters don't know: he's a two-time world championship elk caller who consistently calls in 20-plus bulls every season. He knows how to sound like a real elk as well as anyone alive, understands the biology of elk deeply, and uses that to inform every calling decision he makes. MtnWispr was trained on his methodology.

// WHAT'S ON THE LINE

One bull.
One bugle.
One chance.

The wrong bugle and he turns. He doesn't get a do-over.

Neither do you.

Calf mew

I considered myself a decent elk caller, I have always trimmed the edges off of my calls. Trying to match the calls I found out I was losing a lot of air around the edge of the calls. I used the same call without trimming and putting more pressure on the roof of my mouth and that made a huge difference. … I have killed 2 nice bulls the last 2 years and at 73 I need all the help I can get!

Distressed calf sequence

The instant feedback and coaching MtnWispr provides is incredible. … It only took me 20 sessions over a 3 day period. For me trying to learn without this tool was futile. … I am slowly loosing my hearing and wear hearing aids. As such I am nearly tone deaf, so the visual graph of my pitch is extremely helpful.

Bull-to-cow bugle

The app has changed my calling game. It has given me instant access to how a call should sound and feedback on what to correct with my technique. The problem I have always had is not being able to tell how my calls sound when practicing. I also was “guessing” at what certain calls sound like and trying to mimic that. MTNwispr changes all of that. The learning curve has been cut 10 fold.

Location bugle

Being from upstate NY and not in elk country, I don’t have a lot of people that can give me helpful feedback on my calling. MtnWispr gives me instant feedback on my tone, pitch, and cadence allowing me to practice anywhere, and more importantly, practice correctly. I’ve made some adjustments and my feedback scores have improved quickly, giving me a lot more confidence heading out this season.

Calf mew

MtnWispr has definitely helped me achieve more consistency in my calling. Being able to have each call scored with feedback is huge. It’s so hard to judge your own calling. When I thought I was hitting that ringing tone of a location bugle or the right pitch for a calf I was actually just under it. The feedback helped me get there.

Bull-to-cow bugle

I have found the ability to call and be scored and compared to the actual call very useful. Sometimes I think I hit a good call but actually didn’t. It also allows me to see which of my calls are best for different types of sounds recommended!

Calf mew

Mtnwispr is a great system. You and Joel have really simplified not only the number of calls to learn, the right sound/tone and cadence and when to make them. I haven’t tested the process in real life YET (3 weeks til my CO hunt) but I am more confident going in to this trip than I ever have been.

Calf mew

The instant feedback is great! The app picks up on mistakes that I didn’t even know I was making. I didn’t realize I was dropping down into mature cow sounds at the end of the calf mew. A few practice sessions later it was fixed! Steadily getting better with the bugle too.

Bull-to-cow bugles Field Ready

I started bow hunting Elk ten or so years ago learning along the way through trial and error. Joel has a great way of explaining how elk think, when and how to act, when to not. I needed this ten years ago. I’ve used other bugle recording apps but they didn’t provide the feedback on how to improve. This was a game changer.

// THE OBVIOUS QUESTIONS

Things people ask before they join.

Don't see yours? Drop us a line at mtnwispr@gmail.com. We answer ourselves.

Q.01 Do I need a fancy mic?
No. Your phone microphone is more than enough. You can use MtnWispr on your phone or your computer — whatever you have in front of you.
Q.02 What's your refund policy?
If you're not happy, just send us an email within the first 30 days. We'll give you a full refund, no questions asked.
Q.03 What calls can I test?
Currently we cover the main calls any elk hunter should know: Location Bugle, Bull Calling Cows Bugle, and Calf Mew & Distressed Calf Sequence. We're adding new calls every month.
Q.04 Where do I use it?
Works on any phone or computer. Nothing to download.
Q.05 Couldn't I just record myself and listen back?
You can. People have been doing it for years. The problem is your ear can't tell you you're 38Hz flat on the sustain, or your reed tone is breaking before the note resolves. The app can. That's the whole point.
Q.06 What if I sound terrible right now?
Then you're exactly who this is built for. Most hunters never know how far off they are. The app tells you, gives you specific drills, and you watch your scores climb. By August, you'll sound nothing like you do in May.
