Tag My Knowledge - Store and categorize bits of knowledge you find in books, speeches, interviews, ...

I've been working on a small app to solve a personal issue:
Google Play Store Link

I have many ideas to grow this into something potentially really big, but first I need to see if people are actually interested. It's Android only for now, but it'll be cross platform eventually if there's interest.

Here's the play store description:
"Ever read an important book or watched a speech about something really important? Did you end up with an unstructured mess of notes?

Not anymore! With this app, you can categorize these individual bits of knowledge into categories (for example "wealth" for business or work related things) and add tags like "Hiring employees" or "Company culture".

Later, you can quickly go over your notes whenever you have an urgent issue at hand."
