StressWatch is your trusted Apple Watch app that tracks real-time stress & HRV, RHR, sleep, fitness, mood, water, caffeine, etc. to enhance overall well-being. 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. #Contact us Email: hi@stresswatch.app Subscription prices and terms StressWatch can be downloaded for free.

A great tool for stress awareness!

’ve been using StressWatch for a few weeks now, and it’s been incredibly helpful in raising my awareness of stress levels throughout the day. I love how it uses heart rate variability to give me simple, actionable insights. The notifications are well-timed and often spot on—I use them as reminders to pause and breathe. The interface is clean and easy to understand, and while I’m still on the free version, it’s already added a lot of value. I’m seriously considering upgrading to the paid version for more detailed tracking. Highly recommend this app to anyone looking to better manage their stress and stay mindful!

I wish I could afford the paid version so I could keep track of previous days, and see more in depth data, but it’s a great app. It seems like the instant I get stressed a notification pops up. I find it helpful (I use that as a “breathe” alert). I like when it tells me I’m doing “great” too. Honestly, it’s never been wrong. Definitely worth downloading.

Seems pretty useless

I saw someone recommend this online as a calming app and when I read the app description I thought it sounded really good. It uses the health app heart rate variability (HRV) to measure stress but unfortunately the health app only measures that every 2-5 hours so this app cannot give you timely information in your stress level. Also I didn’t get any notifications at all despite them being switched on and having the app running in the background. It gives you only a minimal amount of basic information and only for the current day so as soon as it rolls over to midnight you’ve lost all of your stress related data from the previous day. Perhaps it’s different if you have the paid subscription but I found the free version rather useless

Not even a bit accurate

I’ve been using this app for a few weeks now, paid for premium.I had to turn the notifications off as they really stressed me out. The watch faces also were really stressful. I would be feeling ok, look at my watch and be met with an unhappy face.Constantly being told it’s overload and to watch out etc.At high stress times it never said anything, most of my high stress days show an “all good” rating. And when I was having ok days it shows overload.Also each time I sit down it shows overload. I have been through the settings and found no useful features.Logging water and coffee is useless.The developers reply to some reviews talking about how the app uses HRV is irrelevant if the app can’t even be anywhere near accurate enough to measure HRV and properly extrapolate it into a useful readout.I wouldn’t recommend this app at all. I was really really hoping it would be helpful and am disappointed as the idea is really good.I do wonder if some people’s HRV is somehow reversed, although that doesn’t seem possible.

Thank you for your feedback!StressWatch calculates stress based on HRV (heart rate variability) and other physiological data. It is normal for single readings to sometimes feel different from how you feel, for example, showing higher stress while you feel relaxed, or Normal while you feel stressed.We recommend looking at your overall stress trends on the app’s home screen. Please keep wearing your watch regularly — our algorithm will get to know you better over time. For more details, please check the documentation inside the app.
