## What is StressWatch?

Understand your stress. Build better habits. Lower your Bio Age.
StressWatch turns your Apple Watch into a powerful stress monitor. Powered by HRV and your health data, it helps you manage stress, sleep better, move smarter, and turn small daily actions into lasting habits that improve your Bio Age over time.

StressWatch has been featured on the Apple App Store in 171 countries and regions —
# Best of August
# The Best Apps for iOS 18
# Better Understand Your Wellbeing
# Essential Watch Apps
# Featured New App
# Our Favorite of This Week

StressWatch relies on your RHR (Resting Heart Rate) and HRV (Heart Rate Variability) data retrieved from Apple Health. 
We'll analyze and interpret the data to determine your current stress levels. We constantly monitor your status and remind your immediately if your stress levels get too high so you can take action right away to help reduce your stress levels. 

#How can StressWatch help you?
- When you work late into the night, StressWatch can remind you that your HRV is low and you're stressed - a gentle reminder to help you understand that it's time to get some rest.
- When you're at a social event and you have to force yourself to smile, we'll remind you that your HRV is low and you're stressed - a gentle reminder to get some fresh air and recharge.
- When you've had just a bit too much to drink, we'll remind you that your HRV is low and you're stressed (because alcohol is a stresssor) - a gentle reminder to let up a bit on the cup, drink some water, and take care of your body.
- You can constantly monitor your HRV levels (and stress levels) from your Apple Watch by adding StressWatch to your Watch Face.
- Paired with proper exercise and adequate rest, monitor and analyze your weekly and monthly stress levels over prolonged periods of time; you'll realize that you're getting better as time goes on.

#Design Concept
We created StressWatch with the sole intention to help people to reduce anxiety in this age of stress and pressure. However, data and numbers do not have any meaning if the user is unable to interpret the data. (Not everyone is a rocket scientist!) So it got us thinking: how can we design a app that delivers numbers and data in a friendly manner that will help users to reduce stress and anxiety. Thus, we created the "Mr.Fizz", which is the foundation of our product design. The "Mr.Fizz" will change colors as the user's stress levels rise.

### 2/5 — Very Slow

*2026-08-24, version 3.3.3*

App has a hard time retrieving data. Not useful.

### 1/5 — Mauvais achat

*2026-08-23, version 3.3.3*

L’application me donne comme message que ma montre n’est pas appariée. Foutaise.
Très déçu d’avoir fait l’achat

### 1/5 — SCAM!!!

*2026-08-23, version 3.3.2*

Warning…not a free trial! I was immediately charged, money taken from my account within seconds of clicking on the 7 day free trial. DO NOT USE THIS APP!!!

### 1/5 — Inaccurate

*2026-08-21, version 3.3.2*

This app is so inaccurate. When I’m experiencing stress it states I’m calm and happy When I’m completely happy it says I’m stressed and need to be careful. I have a seizure disorder and thoughts this could be helpful but it’s a complete waste of money

### 5/5 — Excellent companion

*2026-08-19, version 3.3.2*

Excellent companion for notification, tracking and trend analysis.

### 3/5 — お気に入りですが、ここが残念

*2026-08-19*

毎日チェックしています。いろんな分野で詳しく客観的に知る事が出来るのでありがたいです。以下は不満点①ハイキングやジョギングで、AIに聞くを実行しても回答が得られません。アウトドアは記録が困難なんですかね。ここも確認したいポイントなのに残念です②私は勤務がシフト制なので週末はトレーニングに励む事はほぼ無いのですが週末に向かって‥な活動をしましょうとアドバイスくれるのが残念

### 1/5 — $60.00 for nothing can’t cancel!

*2026-08-19, version 3.3.2*

Takes $60.00 a month from account - cannot cancel-the only option to cancel is to pay to cancel.  Useless!

### 4/5 — 毎日チェックしています

*2026-08-17*

Applewatchで睡眠の状態を測っているので、確認のためこちらのアプリを使っています！Pro版にしています。
ストレス状態もリアルタイムで確認できるので、今自分の体がどういう状態なのか知れるのが面白いです。全体的にデザインがふんわりとしており、キャラクターの表情などとても癒されます🥰
ただし、メニューの名称の問題なのか？、知りたい情報にたどり着きにくいです……日本語版だけなのかもしれませんが。
例えば、過去の１週間のストレス推移を知りたい場合に、確認しにいくのに一瞬迷いがあります。多分、「トレンド」というメニュー名称と、実際の内容が繋がりにくいのだと思います。さらに、トレンド内の週間/月間/年で「日々の傾向」セクションから過去の傾向を追えますが、特定の日の時間ごとの内訳を知りたい場合に、その日付からではなく、下のほうにスクロールして「全てのデータ」から日付を選択して進む必要があり、ここも直感的ではないと感じました。せっかくグラフで可視化しているので、グラフ内から詳細を確認できるようになったほうがよいと思います。
あと、睡眠やフィットネスなどの過去の傾向確認は「アクション」メニューから見れますが、これも迷います…。「アクション」という名称の問題なのかもしれません。また、ストレスレポートは「トレンド」なのに、睡眠やフィットネスは「アクション」からというのも迷いポイントかもしれません。(このアプリのメイン機能がストレスチェックというのもあるのでしょうか)
ただ、このようなアプリで日々の傾向をチェックしているユーザーは、ストレスの状態をただ確認するだけでなく、その原因や傾向を知り、分析したいと思います。それがわかるのが睡眠状態や、フィットネス、他日光浴や歩数などの様々な情報だと思います。それらの情報がもう少し直感的にリンクすると、より使い勝手がよいものになるのかなと思いました！
すみません、まだ使い始めて１週間程度なので、そもそも使いこなせていないかもしれない状態でのレビューとなります。乱文失礼いたしました。

### 1/5 — Always Undefined

*2026-08-16, version 3.3.2*

Constantly lets me know my HRV levels are undefined, yet then shows my stress level is normal. Seems like junk science to me. Gonna try to figure out how to get my money back. This should be fun.

### 5/5 — Great health meter

*2026-08-15, version 3.3.2*

Works great 
Helps me with stress and staying hydrated 
Love it
