Specially programmed computing devices being continuously configured to allow unfamiliar individuals to have instantaneous real-time meetings to create a new marketplace for goods and/or services

A method of proximity-based communication over at least one network, the method including:

• establishing, by a server, proximity-based communication between a mobile computing device and an other computing device, including by instructing the mobile computing device and the other computing device to provide real-time updatable location information, the mobile computing device specifically programmed to communicate with the server including via a graphical user interface, and such that communications from the server maintain user anonymity with respect to the other computing device, and the other computing device configured to communicate with the server including via a graphical user interface;
• determining a stationary location of a meeting for a pickup, delivery, or both a pickup and a delivery;
• providing the mobile computing device with the stationary location for the meeting, directions to the stationary location for the meeting, and a map coordinated with the directions for the meeting;
• and
• dynamically adjusting, in real-time, the graphical user interface of the mobile computing device and the graphical user interface of the other computing device, the dynamically adjusting based at least in part on the location information and on real-time proximity of the mobile computing device and the stationary location for the meeting so as to facilitate a meeting at the stationary location for the meeting.
