Unfortunately, while the 40 Hz light works, no matter what I try I cannot get the 40 Hz sound to work. Other than that, I have really loved this app in the past. -- Davey Dean, 2026-05-28 ### ***** "Great" So helpful for memory -- !TMT, 2026-02-28 ### **--- "So many issues with books" Page numbers in books are all messed up. If you record the page number to pick up your reading tomorrow, that page number will, like as not, put you back to what you read yesterday! Why can’t the app open today with the last page from yesterday? Very frustrating. Editing is horrible with spelling mistakes and occasional indecipherable ‘letter salad’. But it is the best I have found, so far. -- Canoesailor, 2026-01-19 ### ***** "Great games" Love the variety in the games! Would like some options for different background music. -- Sf1g, 2025-11-11 ### ***** "Recently Diagnosed!😭" Daily things help me such as 40 hz App, small laser to head, sauna & red light therapy at gym -- JudyVA Beach, 2025-09-23 ### **--- "Doesn’t actually do 40 Hz" Recently a message has popped up saying the flashing and sound is not 40 hz but 30 due to the limitations of my device. I looked up the refresh rates for iPhones and the lowest is 60 Hz. 30 Hz is not associated with brainwaves that are used in focusing and no study has found that 30hz are enough to help with Alzheimer’s. I’m wondering how many hours I wasted with this app thinking it was doing what it said it would do. -- Ivivjvivuvucycjdgdichcn, 2025-05-12 ### ****- "Fun Brain Health" Generally, this is a really great app. It can occasionally be a little buggy and that would worry me for someone who’s already having cognition issues. But the games are fun and I think the science is out that 40 Hz sound and light can have a positive effect on the brain. And playing games is good for the brain, so what’s not to like? -- Loonyberg, 2025-04-12 ### ***** "Very frustrating" 1.Can you update the puzzle/shapes game? I love that one but have done all the puzzles - 2. Why does the twirling dancer have nipples?? Unnecessarily sexual . How about a ballerina with clothes on 3.the “ Canvie” game— you need to provide answers and stop using abbreviations 4. After using app for several months on a monthly subscription, I am now getting a banner about “ upgrading to premium” constantly . And “ monthly and yearly plans available “ What’s up with that ?? -- lkysyrz, 2025-01-16 ### ***** "ALZLIFE review" I’ve had the extreme pleasure to be introduced to this program 7 years ago. It has since become a daily ritual for my and me. We’ve found that daily use greatly enhances our cognitive skills. It causes us to think. I highly recommend this program for all older people. It will become just as favorite use as the daily paper use to be. Tree top 1 -- Tree top1, 2024-10-13 ### ***** "Doesn’t work with 2024 iPad Pros" The App Support website says that the new iPad pros are supported, but the app says they aren’t and you only get 30hz light. The app was updated last a year ago. They probably only need to update their database, but maybe they’ve stopped supporting this app? Unfortunately, the Contact option on the website requires you to complete a nonexistent recaptia, so you can’t contact them to ask if they’re still supporting the app. Update: the suggestion to disable low power mode doesn’t help. It’s already disabled. They’ve fixed the contact option on their website, so we’ll see if they respond or if they update the app to support the latest iPad pros. Update 2: With the new version, they’ve fixed the issue with the latest iPad pros. I’m looking forward to getting my wife started on the app. I thank the developers for a fast response. -- Steve5555, 2024-10-09 [View all 40Hz Brain Trainer reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## 40Hz Brain Trainer In-App Purchases | Item | Price | |------|-------| | Monthly | $9.99 | | Yearly | $79.99 | | Lifetime | $199.99 | ## 40Hz Brain Trainer Discovered Keywords -
