Great app that does not require any significant permissions. There are a couple of minor things I would like to see, but it does not collect my data and gets 5 stars for that. When I get a question right, I'd like it to load the next one without me having to press the button. When I get a question wrong, I'd like another chance before it tells me the answer. I'd like the answer scroll to move more quickly. I've had a couple of correct answers marked wrong because the bar hadn't stopped yet

Perfect app for testing your day-of-week skills (I prefer Grey Matters day of week approach with memorization reducing the operations you have to perform). One problem: When you speed guess, you can flick the spin wheel quickly (to Sunday or Monday, e.g.) and hit Select before the wheel has settled, causing the "incorrect" message even if you did select the correct day. To avoid the problem, you do have to be reasonably deliberate in setting the wheel to the day you want. No biggie.

It's very good. The only problem is that when you mistake the date and you click dismiss you can't see the day of the week. Also the calendar is a bit hard to work with and it resets when you try to look up a date and switch the tab. Overall the app is what I was searching for!!
