About this app

Intercom for Android lets you place group calls with other Android and iOS(Infinite iNtercom) devices over Bluetooth and Wifi.

Intercom for Android acts like a simple walkie talkie (two way radio):
·No Internet needed. It only uses local communications.
·Minimum configuration.
·Use volume buttons as push to talk
·Bluetooth LE buttons also supported
·No registration.
·No accounts.
·No buddy list.

Sometimes you can't talk directly to people around you:
·Motorbike communications. Rider-copilot. There are special headsets for all types of helmets.
·Inter vehicle communications (up to 100 meters / 238 feet). Motorbikes, cars, etc.
·Sports (ski, cycling, hiking, climbing).
·Noisy environments (construction, concerts, etc.)

Ratings and reviews

Ok the app works great. It discovers other devices on the same lan with ease and was really straightforward. There is one caveat; there is a setting in the app ""Play audio as..." the options are "In call audio" and "music", by default set to "In call audio". On S25+ and S25 Ultra, if you don't switch this to "Music" the app fails to release the voice_call stream properly and the ringtone for subsequent inbound phone calls will route to the earpiece speaker rather than the phones main speaker.

I haven't given it a good real world test yet, but it's already way ahead of all the other apps I have tried. Devices on the same LAN found each other right off the bat. Works flawlessly with bluetooth headset. User interface is simple and intuitive. No dumb features that clutter the app and make it harder to use. It seems to play well with other apps that use the audio (I can hear a call while Intercom is working). Latency is extremely good. Voice activation of PTT is available and seems to work well. Audio quality is plenty okay I have not tested how it responds under poor WiFi signal conditions. If there was one thing I would ask for, it would be an iOS port so we can use this with iPhones as well!

The app has a lot of echoing. i tried to use a headset with mic to overcome the echoing, but the it don't work with the app. update: i figured out that, unlike other media apps, the app doesn't automatically switch to headphones when they are plugged in. i had to turn off the speakers. There was still about a quarter second delay and a little echo.
