It came down from two sides. I kinda burned out while working on Android app and I was expecting much more users and engagement. And I didn't want to create another note taking app - idea for BP is to be one unified place for your data. And notes is only one form of casual-data. Sentiment was like this - Imagine note taking app, calendar app, task tracking app, etc. as destinations on a map. And to get to each of those destinations you need to have special vehicle for each one! So idea was to try to state than notes, calendar entries, tasks, fitness info etc. ar casual-data. And you can have one tool that gives you mechanics to aggregate and manipulate those data in one unified place. Where then you can slice, combine and get insights on your data as a whole.
And its is hard to pitch something so generic!
