## What is StressScan?

StressScan, an app for stress assessment with 3 million downloads, is being transformed into our new app!
Look up “Habitone” to experience the new app!

------------------

Just place a finger over the camera for two minutes, and StressScan will analyze changes in your heart rate and scientifically measure the level of your mental and physical stress on a scale of 1 to 100.
Stress is the root cause of many illnesses. Measure your stress to manage it!

- What is the principle behind StressScan? − 
Many of the functions essential to maintaining human health are controlled by the autonomic nervous system. It is medically recognized that the balance of the autonomic nervous system can become disordered through fatigue and other stress, stemming from causes such as work and human relationships. By analyzing the waveform of your heartbeat as measured at the fingertip, StressScan can analyze the balance of your autonomic nervous system and measure your stress level on a stress index of 1 to 100.

- You can trust StressScan! - 
The technology used by StressScan is based on heart rate variability analysis, which is widely recognized in the field of heart rate analysis and autonomic nervous system research. 
Although heart rate variability analysis technology is not yet generally well known, many medical institutions and companies have taken an interest and are beginning to put it to use. The technology is seeing use even at the cutting edge of stress care, including adoption by the US military to treat post-traumatic stress disorder (PTSD) in soldiers returning from the battlefield, and by NASA for astronaut training and health management.

- Usable in a range of scenarios! - 
· Periodic checking of daily stress level
· Checking the effects of favorite meals and drinks on stress
· Checking relaxation while traveling or at a favorite spot

- Device compatibility -
The app is intended for use with a camera- and flash-equipped smartphone. It is not usable with devices that do not have a camera and flash.

- Usage environment -
An Internet connection is required to use the app. External support for measurement functions is used for complex stress analysis.

### 1/5 — 鬱で休職中なのに？

*2025-05-06, version 3.14.4*

うつ病で休職中なのにストレスなしで精神状態が非常に安定していると何度測定しても結果が出ます。睡眠もまともに取れていない状態なのに？

### 5/5 — ねえねえ

*2025-04-28, version 3.14.4*

今春にサービス終了して消えるんじゃないの？全然まったくこのアプリ消える気配ないけど…

### 3/5 — 片手だけでストレスを測定できるように改良して下さい

*2025-01-21, version 3.14.3*

片手しか使えない私は測定中に表示される次へをタップするとレンズに当てている指が動きえらーになってしまいます片手だけでストレスを測定できるように改良をお願いいたします
厳しいとは思いますがこの点を減点として★2つマイナスしました

### 4/5 — 脈拍はおおよそあってると思う

*2024-12-31, version 3.14.3*

ストレスで脈が飛ぶ感覚がたまにあり、ちょうど継続中にその感覚が来てさてどうなる！と思ったらちゃんとめちゃめちゃ飛んでました。びっくり。
こんなんで取れんのかよ脈、なんで半信半疑でいたのですがまさかの正確さに正直驚きました。

### 1/5 — Useless

*2024-11-26, version 3.14.3*

No matter how stressed I am, I am freaking out about something, can’t sleep, I am jumping and it says my stress level is 1%. Junk!

### 1/5 — The app is stressful

*2024-10-04, version 3.14.3*

This app has yet to actually measure my stress. I turned my phone off thinking that would work. Turned it back on and it still didn't work. So I deleted the app and loaded it freshly. It's still not measuring my stress. So I have labeled this app as stressfuland I'm deleting it for good now.

### 1/5 — Doesn’t work anymore

*2024-08-10, version 3.14.3*

I have an iPhone 15 with three lenses and this app no longer works.

### 5/5 — Android版

*2024-07-18, version 3.14.3*

コメント失礼します。Android版はあるんですか？教えていただていただきたいです。

### 1/5 — Very Innacurate

*2024-06-17, version 3.14.3*

Okay so here’s the deal. I got this app thinking that it would just measure my heart rate and I would get a normal report. But how does it make sense that at RESTING, my heart going from 43 bpm up to 145+ bpm! This app is very bad at measuring your heart rate so do not use it.

### 2/5 — Wrong measurement

*2024-06-08, version 3.14.3*

I was lying down and the measurements showed 48-52 bpm. Sounds reasonable even if on the low side.
Then the measurements exploded to totally unreasonable values above 100.
Maybe the app wants to stress you?
