I am Alex from moWOW, an iOS app and game dev studio. Last year we worked on a few projects that involved iBeacon and Estimote.
During that time, we did a bit of research and brainstorming about the possible applications and use cases for the iBeacon technology and wrote an article about it:
Tudor, dev at moWOW here. We did think about all those terrific examples, but we also realise that bringing them into brick and mortar shops or any other real-life context is highly important. We help clients take this major step by developing iOS apps with great iBeacon integration and smooth user experience. If any of our (more or less crazy) ideas sparked your imagination, give us a sign at hey@mowowstudios.com and let's work together.
