Recurring themes

Monetization & Ads negative
Many users complain about the aggressive monetization strategy, with most games locked behind a 'Pro' subscription. The free tier is heavily impacted by an excessive number of long, unskippable ads that often get stuck or force users to visit advertiser sites, making the app unusable for non-paying users.R24R52R59R64
Bugs & Technical Issues negative
Users report numerous bugs, including subscription access failures, inability to log in, games not working (e.g., 'Grow game' blank, 'Pixel logic' broken), and issues with word games not recognizing valid words. The developer's notes mention 'pesky bugs squashed,' but recent reviews contradict this, with users still experiencing significant technical problems.R9R15R19R61
Customer Support negative
A recurring complaint is the lack of responsive customer service. Users, particularly those with paid subscriptions, report sending multiple emails without receiving a response, especially when trying to resolve login or subscription issues.R15R19R22R71
Content & Variety mixed
While many praise the variety and challenging nature of the games, a significant number of recent reviews lament the lack of new content, with some stating no new games have been added in over a year. This leads to boredom and a feeling of stagnation for long-term users.R5R12R41R104
Cognitive Benefits positive
Many users consistently report that the app helps them improve various cognitive functions, including focus, memory, and overall mental acuity. It is frequently recommended for individuals looking to stay sharp or even those with conditions like TBI or ADD.R1R3R6R7

Who it's for

This app is for individuals looking for challenging brain training games to improve cognitive functions like memory, focus, and problem-solving, especially those willing to pay for a subscription to avoid ads and access all content R3R6R13. It is not for users who expect a fully functional free experience, are sensitive to excessive advertising, or require responsive customer support for technical issues R24R116R22.

Evidence note: The recent reviews skew heavily negative, particularly regarding monetization, ads, and support. This contrasts with the high lifetime rating, suggesting a significant decline in user satisfaction over time, likely due to changes in the app's free-to-play model and technical issues. The confidence in the negative points is high due to their recurrence across many recent reviews.

  1. [R1] 5/5 · US Good stuff: Challenging, but straight-forward enough that my low-budget brain can grasp it.
  2. [R2] 5/5 · US Counselor: Love competing against myself through my daily Peak workouts! Keep those new games coming!
  3. [R10] 5/5 · US Great brain App: It took a very short time for PEAK to become one of my favorite brain App. Games are fun and challenging at the same time. Just love it
  4. [R12] 5/5 · US Peak provides variety: Glad to have such variety of games to test skills. Easy to use and fun to play.
  5. [R3] 5/5 · US Definitely a must-have for severe TBI and related disabilities: Has been great to me! Even support is awesome! With my severe TBI this game tires me out but is fun at the same time. Has actively helped me improve my brain growth and capacity. I love love this app.
  6. [R6] 5/5 · US The metrics are what make this app special: Tracking the various metrics over time brings awareness and confidence to an aging brain.
  7. [R7] 5/5 · US Love this app!: I have been using this app for years and enjoy playing the games and keeping my mind moving. As someone with adult ADD and dyslexia, I highly recommend this app!
  8. [R8] 5/5 · US Mr. colonel. B. Tirrell.: Will. Peak. Helps. Me. To. Improve. My. Brain. You. Make. It. Better. For. Me So. I. Can. Understand. Things. In my. Head. You know. :-).
  9. [R5] 5/5 · US Love it: I bought the full version of Peak in 2019. It keeps me focused and entertained. I enjoy the wide variety of games and the ability to pick a specific game if I don’t want to do a whole set.
  10. [R24] 1/5 · US Completely unusable without subscription: When I first got this app, I could play the daily sample games without a subscription. Over time I had to watch more videos to play free. After several months hiatus, I tried to play today. I could not get through two short games of the "daily workout" without watching 4 videos. The problem is that after the video ad ends, you are stuck in a screen that yo
  11. [R52] 1/5 · US Waste of time: Spent like half an hour doing tests just to not get any result unless I pay $40 or whatever? What the hell, man? What’s the damn point of letting me take the test if I have to spend all my money to see the result? Also, I can only play ONE game, and it’s boring and easy as hell. Useless waste of time.
  12. [R59] 3/5 · US Subscription: Every time I come across a brain training app, there is a subscription and a free tier, and I HATE IT!! Good games though.
  13. [R64] 3/5 · US No: Absolutely not. I got this game as a fun way to get smarter. I planned to not get “PRO” because I don’t need to spend that money. So I didn’t. Now any games I can play on pro so I can’t play anything other than the daily workout. I’m so disappointed
  14. [R69] 3/5 · US Terrible ads: Love the app but not worth it for the disgusting amount of ads.
  15. [R74] 3/5 · US Ads easy to long: The games are fun and engaging and I understand that the free version includes ads. However, when the ads are three and four times longer than the actual gameplay, it becomes excessive and frustrating. There are times I get stuck in an ad and can’t get out. I’ll stick with Elevate and Lumosity. Elevate has ads but not nearly as bad as this app.
  16. [R84] 1/5 · US Can’t get past the ads: I used to use this app frequently and recently redownloaded it. There are way more ads than there used to be and the ads don’t let you close them when they’re done playing. The only option is the download the game so I’ve just been closing the app instead. I get that you have to make money somehow and ads are a way to do that but once the ads become such an issue, I just wo
  17. [R15] 1/5 · US Subscription does NOT work and Poor Customer Service: Purchased the annual pro plan 1 week ago and made several attempts to log in. Followed all the online instructions and reach out to the customer service. Peak’s customer service response is excruciatingly slow, I had to remind and follow up 6 times and wait more than 24 hours to get a simple response on what to do next. Highly recommend for f
  18. [R19] 3/5 · US Used to love this app: I’ve been using this app off and on for several years and have absolutely loved it. This week, every time I’ve tried to use my pro subscription, it will not allow me. I’ve contacted support but have had no response. Just an app I pay for I cannot use. I tried restarting my phone, I tried deleting the app, I tried restoring the purchase, I tried creating a new account - I get
  19. [R71] 2/5 · US Don’t lose your email: I was recently locked out of the email I signed up with. It has been a challenge getting back into the app. Hopefully support will fix my problem soon. It’s no fun not being able to access something that you’ve paid for.
  20. [R91] 1/5 · US Cannot Sign in with Apple subscription: Have never been able to sign in and help has not responded. Waste of money.
  21. [R22] 1/5 · US Zero support: 3 emails to support asking for help with resetting password - no response at all
  22. [R9] 1/5 · US how hard to make a widget?: how hard to make a widget?
  23. [R61] 3/5 · US Grow game not working: I can’t see any letters on my iPad Air for this game. The rest of the games work fine but it is blank and flashing at the bottom on Grow game
  24. [R66] 3/5 · US Need better directions on how to play these games. I have given up!: I like the app, but I don’t know how to play about 50% of the games. I can’t figure them out. There is not enough instruction. I am to the point where I simply don’t play them anymore. What is the point of the app if I don’t understand how to play the game? You need better directions.
  25. [R68] 1/5 · US Still can’t switch out game: It’s been many months and going on years actually where I reported you can no longer switch out a game even though you haven’t started anything yet. This happened after a long time ago app update and has yet to be fixed. Additionally, the word games don’t know a valid word when entered and you get errors. What fun is it when you have a correct word and spelling only t
  26. [R41] 4/5 · US Great game: I enjoy it, but I would like it to change the games more often, more new games,
  27. [R104] 3/5 · US Good but need more games: Exercises are good but not enough variety and no new games have been added in over a year
  28. [R106] 3/5 · US Lack of new content: While I find the app good in general, there’s been no new games in well over a year. They recently added a new game, but it disappeared after a week. So as you play the exact same set of games day after day for over a year it gets pretty boring.
  29. [R144] 2/5 · US Boring: Same game different not what I was looking for he gets boring and I’m deleting this app
  30. [R32] 5/5 · US Ratings: I don’t know how to get in touch with anyone but I have been playing this game for a very long time. I feel like it’s proving to me that I’m not getting any faster or smarter and that I will never reach the 700 milestone no matter how long or hard I try and that is where I think the game is flawed. While I do get better scores on some games, it doesn’t bring me up enough to reach the goal
  31. [R317] 3/5 · GB Not as clever as it thinks it is...: While a great concept, the app could do with a lot of tough love . Running increasingly unstable, and there are two major hitches - it is not possible to sync your account across multiple devices without logging in and out. Secondly, and even more annoying, the deflation of score value every two months or so. You have to constantly get better to maintain your P
  32. [R332] 3/5 · GB Scoring pretty eratic recently: Have been using this app for many years after hearing about it on a news programme. More recently though scoring has become very inconsistent - my performance goes up, scores come down. Very frustrating…
  33. [R110] 1/5 · US Nothing available without paying: You can do an initial assessment but as soon as you get past that, everything is locked down and you have to pay $34.99 to do anything. It should just list the price in the App Store since it’s not functional as a free app even with ads.
  34. [R116] 1/5 · US Worst ads ever!: The ads are longer than the games and getting worse all the time! The bar that does you how far into the ad you are slows down at the end and the ads repeat themselves multiple times before you can play ONE GAME! This has always been my favorite but the developer needs to be a little less greedy and remove the obnoxious ads.
  35. [R11] 5/5 · US Mental power: I have told literally hundreds of people about peak ,it has been so good for me. The stimulation in every area of the brain is very relaxing, over the entire 10 years my culmination as a base score is higher than it was in beginning slow progress that stick.
  36. [R13] 5/5 · US Best Brain Training App!: Love this app so much. The annual subscription is so worth it. Dementia runs in my family so I make it a point to do these exercises as much as I can. I’ve grown in intelligence since I started using this app 6 years ago.
