Installed and tested.
Clean and simple layout, i like that.
Did not read all of the 101 things yet, but from the things i read i did not know one before.
Some are nice to know like #1 or #82. Some are are not that important to know like #22 and some are kind of cool to know like #3 or #101.
I think at #27, #57 and #69 are spelling misstakes? Theres a "(" in the sentences.
Do you plan to add a couple of things in the future?
And maybe you think about translation into other languages too.
I will rate the app and write a short german review at the google play store soon too.
Thanks for this app.
