KnowT is a unified communication tool to facilitate bi-directional and multi-faceted communications between a school, and the parents / guardians of the students of that school. Parents activate their respective profile and get attached to the respective school (which needs to be signed up on the KnowT platform already). Thereafter, parents can send "KnowT"s to the school for various intimations like Transportation alteration, Leave or Absenteeism, Messages to be sent to specific staff member in the school, etc. Each such KnowT is processed in a defined workflow at the school's end, and parents get acknowledgements for each KnowT sent, thus ensuring no "loss in communication". KnowT sends out intimations to parents when their child boards the School Bus, giving information of the bus boarded and time of boarding and de-boarding. Thereafter, the app provides real-time GPS locations of the bus, helping parents to time their arrival at the bus stop to pick up their children. Schools can use the same platform to send out mass messages to all subscribed parents in a single stroke. Alternately, specific 'closed user groups' (CUG) can be created on the fly by the school, and KnowT can be used to send messages only within the CUG users. Schools use the platform also to publish time-tables, schedules for any events/examinations, etc. Schools can also host Polls on the KnowT platform, for allow parents to cast their votes on matters of general interest. Note: Continued use of GPS running in the background can dramatically decrease battery life
