I'm an individual looking to break into app development and am starting with a set of apps (actually one app but with different variations) inspired by apps built by Monkey Taps LLC. https://play.google.com/store/apps/developer?id=Monkey+Taps+LLC&hl=en&gl=US

As I near completion of the app code, I've realized that due to my lack of knowledge in content, I have no idea how to obtain open data. Are there any sites that provide data dumps (even paid, as long as they are less than $50 per data source)?

I'm specifically looking for options on obtaining data for a dictionary app, a "facts" app, affirmations apps, and even a healthy tips app.

However, as someone without a source of income, I can't hire another person or buy an expensive data source for the apps.

I believe the experienced people at HN will know what I can do to obtain data for the above apps.

Thanks
