Startup Idea: Customizable Digital Planner Software
I am a very meticulous and organized person. To that end, I keep a planner to help keep my days organized. They're great for making notes, keeping track of events, etc. I've tried several different brands and versions, and it can be difficult to find one that meets my exact specifications. Some are good for keeping track of appointment dates over long periods of time, but bad for noting more every day activities, and vice versa.
I think it would be an excellent idea to have a software that would allow you to easily create your own planners and organizational devices. This would be a big deal for people like me, and for others who probably have busy schedules and specific schedule-planning needs, such as teachers, doctors, lawyers, etc.
An idea solution would also possibly have an app in which you could have an exact digital version of your planner, in case you forgot the planner itself, or for the more technologically oriented.
