Startup Idea : Smart travel planner

I want to make a smart travel planner. Currently there are already existing travel planners. But my idea is to combine the alarm of your smartphone, a travel planner, and a (school) schedule into a smartplanner. So if you need to be tommorow morning at school at 08:30. You just fill in the app the time of arrival, the destination and your current location. You also fill in the time you need from getting up in the morning and leaving your home. After you did this, you press the plan plan my journey button. Now your alarm is set automatically, and the journey schedule will be shown tommorow morning after the alarm goes off. Another functionality is that if you switch the autoplan toggle, you dont need to set your arrival time. The app will look automaticaly in your school schedule an plan the journey. I have already started designing and building the app. I'm trying to build the app in React-Native, because im new to this framework I am encountering some problems. If you have any questions or want to help me with this project you can mail at mansurdehpoor@gmail.com
