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.
Hack
I got the global high score in just a couple minutes by spamming the button and guessing the number I never got to pick my name for the high score so it’s stuck as diamond Dana
The app is good to start the raining of card counting for beginners.
One improvement can be added display the correct count when the user miscount
Very very basic needs more to be useful
So I like the simplicity of this. Try your best to count as many cards in 30 seconds. But like a lot of others mentioned on here, it needs to show how far you were off on the count, not just wrong. Cause I could swear I’m right sometimes and it just tells me I’m wrong. Makes me wonder if there is a bug in its count or maybe I’m messing up somewhere. Also it’s be nice if there was more ways to count them a single flip deck. Like if there was an actual poker table with hands and a dealer. May help to shift your eyes around.

Good... but how will I learn?
It’s decent for learning cards quick. But it just says wrong or right... there is no teaching. And there is no telling what the count was if you’re wrong. Needs that in an update.
Great app for on the go
Great app for on the go counting. I really wish it told me how far off I was when I miss the correct count.
It would also be an amazing feature to “review your deck” at the end of the 30 sec. This feature would show you where you went wrong.

Good starter app
The app overall serves a general purpose and we can all get better using this app. But I have experienced some difficulties in my 48 hours of using 21 Trainer.
I have had a problem looking at the high scores for myself and global.
Once that is solved I would like to see the app include some features.
For starters, I would like to be able to chance the time clock in increments of 15 seconds. This would help more experienced counters test themselves. Also it doesn’t show you the running count at the end if you were to have the wrong count. I also think they should add in what the true count in the shoe is.
If these changes would be implemented in the application, it would be perfect.
