One2One is a video call you start with a link, and only the person you send that link to can join. You create a room, share the link with someone you already know, and the two of you are talking — with nothing for them to install. INSTANT START • Create a room and share the link, or read out the short room ID • The other side opens it in the app or straight in a browser — there is nothing for them to install • A call is one to one. No lobby, no "waiting for the host" WHO CAN JOIN • Only the person you send the link or the room ID to. There is no matching with strangers, no discovery, no public rooms and no directory of people to browse • A room holds exactly two people. Once you and your guest are in, nobody else can join • The room exists only while the call lasts, and its link stops working once you hang up JOINING IS ALWAYS FREE • Anyone you invite joins for free, on any platform, straight from the link • No paywall for guests and no daily counters — the person you called never pays DURING THE CALL • Camera, microphone and speaker in one row, and a picture-in-picture window when you leave the app • Front or back camera, mirrored preview, fit the picture to the screen or fill it • Schedule a call and drop the invite straight into a calendar • With Pro you can turn your partner's camera or microphone on and off — and either side can block that with one switch PRIVACY BY DESIGN • Nothing to fill in before you call: no profile, no phone number and no contact list to upload • The call goes device to device wherever the network allows it; where it does not, an encrypted relay carries the packets. Either way the media is encrypted between the two devices and no server can read it • A room exists only while the call lasts. There is no call history, no recording and no copy of your conversation anywhere ONE2ONE PRO Without a subscription you can still join any call by link or ID and talk for up to 20 minutes per call. One2One Pro is for the person who starts the calls: • Create rooms and invite links without limits • Schedule calls and send them to a calendar • Calls of up to 4 hours instead of 20 minutes, when both people are in the app • Turn your partner's camera and microphone on or off during a call One2One Pro costs 4.99 EUR per month or 49.99 EUR per year, and new yearly subscribers get the first 7 days free. Every fresh install also begins with a free week of everything, with nothing to buy. The subscription renews automatically unless it is cancelled at least 24 hours before the current period ends; you manage and cancel it in your store account settings. "Restore purchases" is on the subscription screen. LANGUAGES English, Ukrainian, Russian and German.
