Fixed a bug where you where not able to see your high scores.

Cool app

Nice app with nice aesthetic but needs to be tested for bugs. There are lots of bugs and exact same cards shouldn’t be able to appear subsequently.

Good but could be better

I wrote a counting practice program for the pc but purchased this because I’m not an iOS coder. I have 2 problems. First, sometimes it shows the same card twice. I thought i hadn’t advanced to the next card so tapped again to advance the card. Consequently my count was off. It shouldn’t show the same card twice. Second, I think it counts the last card before showing it. Since the time is up. It asks for the count and never does show the last card. This should be fixed. Otherwise it’s a great practice app.

Well made. A couple of flaws.

Not being able to see the last card on top after the thirty seconds is a HUGE problem. Often I will click for a new card as soon as the time is up and it takes the new card into account, even though I didn't see it, or if I did it was for a fraction of a second, ruining the test. Also not giving a sound que or visual que for a new card that is the same as the one before it often gets me mixed up because I think my tap didn't register leading me to skip a count.

Math is wrong!

Lol first off the pictures of the cards In the instructions are wrong. There’s no 6 card just 2 fives. Also the count is off very often.

Could be better

Good app. It would be great if it gave the actual count when incorrect.
