One of my startups leveraged mobile videoconferencing to provide real time coaching lessons. We implemented https://tokbox.com. It is platform independent, relatively easy to implement, and highly scalable.

They have plenty of customer success stories to back it up as well. https://tokbox.com/customer-stories

If you have additional questions around implementation, I am here to chat.

Best of luck!

I assume you mean a mobile web application (in-browser based), as opposed to a native apps? If that is the case you have to go no further then searching for deeply functional mobile and responsive sites like mobile.twitter.com .

As far as OS-agnostic mobile web applications for video conferencing—no better place to start then Skype.

Video conferencing software has exploded in popularity over the last year. With people working from home and remote work becoming the new normal, businesses rely on video conferencing services to communicate. But not all video conferencing software is the same. The tools you use to video chat with your friends and family across the across are not necessarily the best business communication options. If you are running a small business or just need to occasionally meet with a small team, you probably will not run into problems with restrictions. There’s nothing worse than being on a video conference with a poor stream. It can really distract from the purpose of the conference. Each participant’s individual Internet connection will obviously impact the quality as well. However, some software is better than others in this category. The best way to determine the video quality of the software is by experimenting with free trials and reading reviews from current customers. If you are using video conferencing software for work, it is useful to have an all-in-one collaboration solution. Now everyone can collaborate from a single platform, instead of bouncing back and forth between different software while on a video conference call. Cloud software or browser-based video conferencing software is extremely flexible. For example, let’s say you have a sales team that uses video conferencing to communicate with prospects. Desktop apps are commonly used for in-house video conferencing. The best video conferencing software will support all major operating systems. Mobile video conferencing is crucial for people who need to join calls on the go. However, the experience is enhanced by downloading the mobile application from your video conferencing provider. Nearly all the best video conferencing software on the market today will have some mobile conferencing features. Some businesses require a complete meeting room system for video conferences. If you are having a video conference call in an executive board room with a dozen people present, a laptop at the end of the table is not going to cut it. Blue Jeans has a wide range of video conferencing options for businesses of all sizes. Depending on your needs, there are four different Blue Jeans video conferencing products for you to choose from.
