No Sound on iPhone 17 Pro Max

I have faithfully used this app for more than three or four years up until I got my iPhone 17 Pro Max about a year or so ago. 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.

Great

So helpful for memory

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.

Great games

Love the variety in the games! Would like some options for different background music.

Recently Diagnosed!😭

Daily things help me such as 40 hz App, small laser to head, sauna & red light therapy at gym

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.

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?

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 ??

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.

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.

Response from developer

Dear Steve, Thank you for your review! The new version resolves this error. The problem was incorrect counter. The screen was blinking at 40Hz, but the counter reported 30Hz.

Not impressed

Just started using this app.
What I really wanted was to be able to just have the flashing light , selection of music I can chose from and a timer so I can make my selections, set the timer and look at my phone in front of the screen to catch up on my emails or whatever.
Seems like a pretty is thing to add, no?

Great games!

My Mom is 94 years old and I could see her memory has improved since she started playing those games like Memory Rings and Memory Pairs.

Fun Games!

I got this for my husband who has vascular dementia. He enjoys playing some of the easier games and when he finishes, I grab the tablet and plunge into my favorite, Spider Solitaire. We both use it with the flickering light (which can be turned off). Our older iPad was bought because it is campatible with this app. I don't know which models will deliver the 40Hz needed to be theraputic. Lots of other fun games available in the app too.

Dear Steve, Thank you for your review! Please disable the 'Low Power Mode' to experience 40Hz light.

Still needs work

Provides the advertised light and sound. But various problems. Books never download, so aren’t available. Some games have annoying repetitive music that can’t be turned off without just turning off the sound on your device. Most don’t have detailed enough descriptions to allow you to play if you didn’t already know how. Some (such as Spider Solitaire) sometimes tell you there are no moves left when there are.

Great product

I have been using AlzLife for 3 weeks now. The games are fun. Surprisingly enough I enjoy the Jewel Crush game with its piano background music since I play the piano.

In the last few weeks my ability to find words in word search games like Waffle and Word Finder has increased so much I hesitate to say it but it is like lightning speed.

I have consistently used the program on my iPad for an hour a day with wonderful headphones. I started out using minimal light and a lower sound and increased as I became accustomed to it.

I used the Luminosity app for several years, but Alzlife has been a great choice and I highly recommend it.
There are games that are basic and games that are more challenging so Im sure you will find some games that you like!

There are card games, chess, checkers, word finder, math, picture finder games of people, animals and things. Try it, you'll like it, and for me it is working great. I highly recommend it.

Best regards...

Maybe it works, sure looks like a cash grab.

Claims ‘all proceeds go to alzheimer’s research’. Okay, where?MIT, where the idea came from?
There is another app with similar light and sounds at $3 lifetime this app is $200, lifetime, $10 a month or $80/year. Yes it has a lot of games. Most you can play free on line. I play Sudoku on line, free at all levels. The free games on this app are for 4 year olds.
Hoping for MIT to offer an app, THAT I could trust.

Not the cure all we had hoped for

We have been using this app for my mom for over 9 months - at least an hour a day and haven’t missed a day. She has completed over 386 hours and 21,000 games in that time.

While it has help to relieve anxiety and improve sleep it hasn’t helped with short term memory or retaining how to perform daily activities.

We are grateful for what it has helped her with but disappointed it hasn’t helped with memory and performing daily activities- which is steadily declining.

Hopefully others will see better results than my mom.

I love the idea and the science but…

The user experience and user interface need serious improvement.
