‘KahanHoApp - Where are you?’ is a free and simple way to share your location in real-time to your known ones. Publish your location, co-ordinate a group, know when somebody is going to be late or guide them when they miss the exit point or take incorrect route. All of this in real-time and you can always see who all are watching you.
Send a KahanHoApp request to let them know where you are or ask them where they are. Have a group outing and track where everybody in the convoy is.
Its safe and simple. Just publish your request using any channel (WhatsApp, SMS, email etc) and they can track you for the duration. Stuck in traffic, just extend the tracking duration. And to top it all, you decide the frequency of location update so power usage is less.
