Make your next one-on-one in-person conversation more reciprocal, bidirectional, and collaborative. IMPROVE YOUR MEETING'S DYNAMICS Capture objective, reliable measurement - the proportion of meeting that you listened/talked: * After the meeting compare your perception to the actual measurement. You may be surprised by how much your subjective opinion differs from the objective facts. * During the meeting check your participation rate periodically. Decide if you should adjust your behaviour - either talk more or listen more. Your meeting partner may also decide to use the feedback from WhoTalks to adjust how he/she participates. SIMPLE TO USE 1) Open WhoTalks app on your phone and login using AppleID (using fingerprint) 2a) Place your phone on the table next to you and press the "Host meeting" button. 2b) Have your meeting partner put his/her phone in front of him/her and press the "Join meeting" button. 3) Each of you will see your own "percent listened" number. Decide for yourself if you should try to listen more or to participate more. Our app determines who is talking by continuously measuring when the sound waves hit the microphones on each phone with high precision. In order to get accurate results, please place the phones: * directly between you and your partner, or a little to the side, but not too far aside. * at least 3 feet (1 meter) apart, which means that the distance between speakers is at least 5 feet (1,5 meters) Note: Current version of WhoTalks works in only for one-on-one meetings. In the future you will be able to use our app in meetings with three or more participants. TRY FOR FREE Host your first 2 meetings for free. Meeting partner always joins for free. Use these 2 free opportunities to check how accurate is your perception of your own listen-to-talk ratio. Install Now!
