Just right challenge

When it comes to strengthening your brain it is very important to hit the “just right challenge”. If games are too difficult, players get frustrated and do not want to come back on a regular basis to continue. If games are too easy there is not really any point to playing them, other than wasting time.
The program appears to starts you at a reasonable level of challenge and based on performance continues to give the player harder, the same, or easier activities. This allows for growth and improvement at a pace that allows the player to feel successful.
I highly recommend Left vs. Right!
My only problem is when I let the day slip away without doing it, then my “consecutive days of training” goes back to zero. But that is a matter of my time management and setting priorities, not a fault with the game.
Try it for a few days and see how much you improve in a short time.

Not just another mind-numbing app - but pricey!

I enjoy apps that keep my brain active and stimulated, and me busy when I want to pass the time. This app does just that. So far, this app is entertaining, and also gives my brain a bit of a workout. It’s not just another mind-numbing app. Of course, I enjoy those, too, but with a brain injury, I like to find things that fight the damage, that may stimulate new pathways, and help my focus and memory. It’s also an app my kids can play, which is always a bonus. On the downside, it only lets you play three games on the free edition before it shuts you down for the day. It says that you can watch a video to unlock another game, but so far that doesn’t seem to work. So I’m not sure you actually can. I may give the free trial a go to see if it’s actually worth paying the (IMO) steep price. I usually don’t spend that kind of money on an app, not when there are so many free to less-expensive ones out there. So, I also will keep looking at other apps. I wouldn’t mind unlocking everything for a low price, but $40 a year is a bit pricey to me. I’d rather spend my money elsewhere. I deducted one star for the price, and one for the fact I can’t get the video to work, so I can only play three games a day, which isn’t much. If it weren’t for that and I could play more, I would have given it 5 stars.

I have focusing problems that I go to the doctor for and this I have recommended to them to start using on other kids. I love this game and it really helps with focusing issues. I do have my eyes hurt a bit after playing but that is because they are working hard. I have found a few kinks but that will not take my five-star rating off of this great game. I had started looking for games to help my kids get better at this stuff but all the good ones cost money every week! When I saw this one I knew I might have found a hit. Well, seeing here about a month later, I was just right. This app I recommend to millions of parents and hope their kids find the never ending happiness and challenge that has come to me and my kids!😄
