## What is Strobe Therapy?

Strobe Therapy regulates your brainwave by the rhythm of blinks of lights and leads you to a deeply relaxed state. If you use it when you go to bed, you can expect a good sound sleep. You can also expect it to reduce stress and to improve cognitive function.

It's easy to use the app. Just press a button, then the LED light of your phone will start blinking at high speed. Let the strobe lights hit your eyebrow center after you have closed your eyes. That is all.

It is highly effective for relaxation. Take the shower of the strobe lights without moving your body. While your eyes remain closed, you will start to see various things such as colorful geometric patterns, psychedelic mandalas, beautiful natural scenery, etc. As you relax deeply, what you can see will change. Just be aware of what you can see. It will naturally lead you to a deeply relaxed state.

You can't fully relax while you are holding a device in your hand, so it would be good to lie on your back and place the phone directly on your forehead. If the leak of the light disturbs your neighbors, cover it with a thick towel or something.

It's rare but, depending on your constitution, there may be danger of inducing photosensitive epilepsy. Please use this app at your own risk. If you are oversensitive to light, refrain from using this app. Besides that, excessive prolonged use of the app may induce side effects such as dizziness. Please take responsibility for adjusting your exposure time to the light.

You might think that you will be awakened by being showered with the strobe lights before you go to bed. But actually, it is mysteriously effective in making you relaxed. And somehow it seems to be good for eye fatigue too.

Those who are insomnia, those who tend to think too much, those who do intellectual work right before they sleep, those who are restless and can't calm down, must try this app. Before the emergence of Strobe Therapy, this experience has been possible only by using a very expensive dedicated machine for meditation and therapy. 

Ajina Light, created by Guy Harriman, is one of those dedicated machines (https://ajnalight.com). It is an excellent machine with much brighter lights than smartphones. But a problem with Ajina Light is its price. It costs 5555 US dollars! So it is not something that average people can buy and be able to use before going to sleep.

Strobe Therapy is not only inexpensive. It has unique features that those dedicated machines do not have. In particular, the function that repeats multiple sets while placing break times is distinctive with this app. It is highly effective in relaxation.

The mysterious effects of flickering lights have long been known. Ptolemy, an ancient Roman scientist, generated flickering with sunlight and a spinning wheel. He noticed that a feeling of euphoria could be experienced by that. Modern French psychologist Pierre Janet used it to relieve hysteria. Aldous Huxley, the author of The Door of Perception, noted that flickering lights have a similar effect to hallucinogens such as LSD and Mescaline.

Several scientific studies have revealed that brainwaves can be controlled by the frequency of strobe lights. In 2016, Nature published a scientific paper that shows amyloid β, a hallmark of Alzheimer's disease, can be removed from the brain of mice by strobe lights.

### 2/5 — Can't purchase full version!

*2023-11-26*

There is no way to contact support. We get prompted to buy the full version of the app, but nothing happens if you try to click on the "buy full version " link. I like this app and I WANT to buy it, but we can't??! Please fix this'

### 2/5 — Can not link to full license purchase

*2023-09-10*

I can only access free version because the link to the full license purchase does not work

### 5/5 — I love this long time

*2023-04-26*

It’s a great app. Can’t even explain what I use it for but it’s the perfect medicine for a number of things.

### 2/5 — Purchase license link does not work

*2023-03-21*

You’re losing money! Let me buy a license! Link isn’t clickable!

### 4/5 — The free version has worked every time for me

*2022-02-12, version 1.2.6*

Im not sure about the validity of the negative reviews. Some people respond differently to the various therapies out there. The reason there are so many options to choose from is that people are different and our minds work in different ways. Depending on what you are trying to use this to treat for from insomnia, stress, other medical issues or PTSD, maybe you need something different. For instance, why do some people receive and respond to Ketamine therapy for PTSD but not everyone? This may or may not be for you, but it is free to try ahead of purchasing.

### 1/5 — Failed execution

*2021-04-18, version 1.2.6*

This is an interesting concept but the user interface is terrible and instructions entirely unclear. There is also no support from the developers. 

Also placement of an iPhone on the forehead is problematic depending on the size of the phone. If you have an SE versus 12, the experience will inevitably be inconsistent at best. 

I have personally used several of the programa and have felt no changes in levels of relaxation or sleep induction. I didnt even get a placebo effect.  

The basis of the app is pseudoscience and just another unscrupulous example of profiting from those seeking help with legitimate medical problems. To the developers: shame on you.

### 5/5 — Straightforward

*2020-07-26, version 1.2.6*

Bought this on a whim looking specifically for brain wave entrainment strobe apps, paid the $3.99 and The functionality is straightforward. First strobe experience, but fairly decent mood enhancement and straightforward functions. No complaints!

### 5/5 — 5 stars to me all the way

*2020-07-02, version 1.2.6*

I’m surprised at the low rating of this app, as I’ve found it to be 5 stars based on its numerous features / settings, and the next level experiences I’ve been having using it paired with binaural beats. I have recommended this app to a few friends that have all felt the same.

### 1/5 — Don’t buy

*2020-01-21, version 1.2.5*

I paid the three dollars or whatever so I could set the playing duration longer that the one minute and some seconds allowed and after paying setting duration was still not allowed.

Keep the app up to date or get rid of blocking duration time and make it free.

I hope to be able to contact Apple to get my money back.

It’s useless if you can only run it for under two minutes.
