Hi! I recently encountered the same need and found a great resource called heylocate.mobi which helped me a lot. It has location tracking features and more. It also allows for messaging, photo sharing, and more. I like its simple interface and high location accuracy. Not only does it let you track your location, but it also offers features for messaging, creating group chats, and even delegating tasks. Very handy, especially when you need to be aware of several people's movements at once.
