A lot or a little?
Parents need to know that Walkie-talkie - COMMUNICATION is a social networking app for iOS and Android devices with ads in the free version. Kids can collaboratively tune to the same channel and use the app to talk to each other like they would using a traditional walkie-talkie -- but with the added ability to communicate with people across the globe. Though there are lots of channels, and the odds of choosing the same one as others is fairly low, people can tune to the same channel at the same time and listen in on the conversation without being invited. So, kids could potentially channel surf to potentially find people they don't know. Read the developer's privacy policy for details on how your kid's information is collected, used, and shared and any choices you may have in the matter, and note that privacy policies and terms of service frequently change.
