NameSpace app is free.
I was wondering if a tip jar makes sense, so here it is. And now, a coffee.

Update v0.6.2

I‘ve set it up using stripe, my first time outside of AppStore territory. The buttons take you to stripe check out pages.

Does anybody else have hands on experience with tip jars in apps?

@hannesoid I have tipjar in @drinkcontrol (shown to paid users only because it does not unlock any features) and some people actually use it (even after they paid for premium features in the app)!
@xjki @drinkcontrol that's interesting to see, and I like the cute wording!
