Warning, this is another post NOT about fitness, but something I find useful!
VOXER is another FREE app that I LOVE and use. I was introduced to this app during Crossfit Central's Women's Challenge. Us Women coaches used it to communicate during the Shoal Creek part of the Challenge due to the spread out location. It was perfect for that. Its also great for a quick response or memo to a friend. Siri is great and all but if you don't look at what she typed, you could send some CRAZY messages. Unlike a walkie-talkie you don't have to be on a certain channel or in a set radius, I voxer my mom who is in BMT. Enjoy!
