Two languages.
One conversation.
Tap your language and talk. Mostić says it out loud in the other one, in natural Serbian or everyday English, so family and friends can just talk.
Free. No ads. No accounts. Invite-only for now: ask whoever set up Mostić for your family code.


Serbian that sounds like a person
Serbian changes with who's talking and who's listening. Mostić knows if you're speaking to a woman or a man, and whether to say the friendly ti or the polite Vi.
“Are you tired?”
“Come in, sit down.”
„Baš mi je drago što ste došli.”
Tap, talk, listen.
No menus to learn. Two big buttons, one for each language.
Tap your language
Green for Srpski, yellow for English. Tap and speak, or hold it like a walkie-talkie.
Say it the way you'd say it
Talk normally. Mostić writes down your words so you can see it heard you right.
Hear it in the other language
The translation is spoken out loud and stays on screen in big, easy-to-read text.
Made for real family moments
Two phones, one conversation
Connect a second phone with a QR code. Each person speaks into their own phone and hears the other in their own language.
One phone, across the table
Both buttons on one screen, so two people can share a single phone.
Latin or Cyrillic
Read Serbian in latinica or ћирилица. The whole app switches with one tap.
Quick phrases
Everyday lines are one tap away, and you can save your own favorites.
Type when it's loud
Busy dinner table? Type instead of speaking and Mostić still says it out loud.
Easy on the eyes and ears
Large text, a slower voice, and buttons big enough for any hands.
The other person doesn't need the app.
Someone shows you a code. You scan it. That's it.
- Scan the QR code with your phone's camera
- It opens in the browser, with nothing to install
- Pick your language and start talking
- The link works for 12 hours, then closes by itself
Made for our family first.
Mostić started as a way for one Serbian mom to talk with her friends and family in America. If it helps your family too, that makes us very happy.
