Murmur is a simple, private way to practice phone calls using realistic AI. If you hate calling doctors, offices, customer service, landlords, recruiters, or literally anyone you don't know… you're in the right place.
A lot of us grew up texting everything. So when it's time to actually make a call, the brain just goes blank. Murmur fixes that by letting you run through the whole conversation first. You talk out loud, the AI talks back, and you get to rehearse the exact call you're scared to make.
It feels like practicing with a friend who doesn't judge you, doesn't interrupt you, and never remembers the embarrassing stuff.
WHAT YOU CAN PRACTICE
– Calling a doctor or clinic
– Booking appointments
– Talking to your landlord
– Handling customer service
– Asking about a job application
– Mock interviews
– Campus admin calls
– Returns, refunds, awkward situations
– Anything you want, with custom scenarios
FEATURES
Realistic AI mock calls that react to you in real time.
Conversation roleplay with different personalities and difficulty levels.
Call practice for everyday tasks, adulting stuff, and stressful moments.
Interview prep with follow-up questions and natural back-and-forth.
AI rehearsal for any scenario you're avoiding or overthinking.
Tools to help you speak clearly, stay calm, and improve communication skills.
No recording, no monitoring, no listening to your actual calls. Everything stays inside the app.
WHY IT HELPS
Most phone anxiety comes from not knowing what the other person will say. Murmur lets you hear it ahead of time. You can practice until the call stops feeling scary and starts feeling normal. After a few sessions, making the real call feels way easier.

This App is amazing for practicing calls, and is a great idea. One thing I wish this App would do is have more free calls. Immediately after my first call, I couldn’t make anymore calls without a subscription. Hopefully I can continue using this app, but right now I feel there should be more free calls, thanks.
Good idea, but I’m not paying for it
Keegan.rose
The concept seems good, but I’m not interested in paying for a subscription just to use it. It would be a lot better with a free version, a trial, or at least more ways to use the app without paying right away. It would also be nice to have actual ranks and social features like following other users. Right now, the paywall is too immediate for me to want to keep using it.
Developer Response
Hi, thanks for the feedback!The paywall is dismissible, and you can try the app without paying: all onboarding calls are free, plus a few more afterwards to test the waters. We don’t offer trials anymore because we've made calls unlimited for subscribed users.There’s already light ranking and social sharing in the app, but for now we’re keeping the core experience private and low-pressure, and we’ll reconsider the social side as the user base grows.Thank you for giving murmur a try!
My call disconnected the second I started
Walkerdegraaad
I didn’t get to make my “free call” then it immediately tried to charge me money. This was a terrible experience. I know you will comment back and say something like api cost money. I get it. But this model is just crummy and you need t change it.
Developer Response
Oof, sorry about that! Onboarding calls are free, and a dropped call shouldn’t burn any of your “try it” calls either.If you email ios.layered@drobinin.com with roughly when it happened (and your iOS version), I’ll top you back up and help figure out why it disconnected - it’s usually a network/VPN/permission edge case.
Doesnt work
Reviewer for apps2098
I really liked the concept but it genuinely doesn’t even work, keeps saying call not connected snd then says I’ve used my free call even though it didn’t work.
Developer Response
Thanks for the report.Onboarding calls are free, and you also get a few extra calls afterwards to try the app - a "call not connected" error shouldn’t consume any of them.We’ve shipped a few updates since this review that improve call setup and failure handling. If you’re up for giving it another go, please email ios.layered@drobinin.com with roughly when it happened (and your iOS version) and I’ll top your calls back up and take a look at what went wrong.
