Editors’ Notes

You use all kinds of specialized equipment at the gym to keep your body in shape, but what about your brain? Peak is a comprehensive collection of exercises designed to hone your memory, sharpen your problem-solving skills, enhance your mental agility, and more. Daily workouts covering up to five areas of focus will leave your mind feeling limber, and you can track your results over time and even compare them to other Peak users in your age group. Best of all, mental gymnastics don’t cause painful brain-sprains.

I think what really pushes people away from this app is the subscription which do very depending if there’s a sell going on. I upgraded to pro and am now paying 1.37 a month and don’t mind that price. There are issues here and there (LIKE EVERY APP) because nothing in this world is perfect. But I gotta give it to the developers. These games work. You’re giving your brain a daily workout which will help you throughout your day and your future. I think it’s worth the monthly subscription for me. Because I can’t remember the last time my brain got a workout like this. And you instantly feel the difference after playing and that’s MIND BLOWING! I feel if people give the game a chance, pay for the subscription, if it’s worth it for you (If money does play a roll I would wait for some sell), keep writing reviews to help the developer fix the few issues the app DOES HAVE, maybe the developer will listen to the fan base and make the right improvements and the app will become even better than it already is. All I’m saying is that the Human brain is a STATE OF THE ART WEAPON. Why not keep it sharp and active in all areas. Help the app grow. I know I will.

Games are so addicting good for you!

It's important to exercise your brain in many different ways! I can tell the days I don't do my workouts before work. When I don't, It's seems like I'm not as focused or awake and tend be more groggy. Also, (as embarrassing as it is) I've always struggled with words due to my dyslexia, and this has helped me get over the "pressures" of finding/spelling words. Turns out I'm actually quite good at them (better than my husband and it drives him crazy!) I guess I've lived my whole life telling myself I'm not good with words, so I wasn't. But now Peak helped me see that's not entirely true. Some/most games are so much fun too! To spend one on one interactive time together, my husband and I will pull out my phone and take turns playing games to challenge each other. I only wish we could select a "guest" button when he is playing so he doesn't effect my mental progression charts. I only bought into it because I got it on cyber Monday for $.99 a month. Worth the $.99 but I would never have signed up for $3!
