### 5/5 — Great Sauna and Dip tub app

*2024-06-02*

The newest version has all the thing you need to record your sessions.

Sauna, rest or Sauna dip tub etc. Any combination to record a full session no matter how you choose to relax.

**Developer response:** Thank you, I'm so glad I could help you with your sauna! I would be honored to help you with your sauna. I am looking forward to making it even better, so please keep supporting this app!

### 5/5 — Great app

*2023-11-04*

I really enjoy the app. Even some features I requested were implemented! Great developer. I would like to request a feature to make an Apple Watch complication. Unfortunately I have to open the app from the list each time, but would be great to open from the watch face. Thanks!

**Developer response:** Dear _DougWessel, Thanks for the meaningful review to improve SaunaTime app.

Making the Cold bath timer and Rest timer optional was a whole new idea to me!! I will consider implementing it. Please wait until it is implemented to improve the user experience of the app.
Also, regarding the sauna timer, for those of you who love saunas, I have extended the timer from the original 12 mins to 20 mins.

Again, I plan to make adjustments regarding the timer time. I apologize for the inconvenience to you and hope you can wait a little longer.

Please continue to support SaunaTime app as I continue to improve and update the app's features to support your sauna activities! Have a nice sauna activities!

Hello _DougWessel, I have spent the last two weeks thinking about what UI/UX would make the app better with your feedback and have completed the implementation. I am already beta testing the updated app and if it passes Apple's review, you will be able to try this app in your hands in the near future.

### 1/5 — No point

*2023-09-13*

Totally pointless app with very little features. Not worth the $

### 4/5 — Infrared Sauna Support

*2023-03-17*

This app is great, I've been looking for a way to track my sauna sessions. I regularly use my Infrared home sauna or sauna blanket and visit a Korean spa about once a month. I would give 5 stars if the app allowed me to switch between steam and infrared saunas in the settings. Otherwise the most useful wanna tracking app available.

**Developer response:** Dear thecrystallineoracle,

Thank you for taking the time to review me! I am listening to our users and working to improve the app. As you mentioned, the features you suggested are currently taking some time to add, but I am considering implementing them in a future update. I look forward to your continued support as I strive to make the app even easier to use and more convenient for you. I look forward to hearing from you anytime.

### 1/5 — Doesn’t work

*2023-03-09, version 1.1.0*

Do not purchase!! I purchased this app in hopes of tracking my sauna times but the app is useless. It asks you to set a sauna time and an alert for heart rate but never let’s you start the timer making this app completely useless and fake. Don’t waste your money!

**Developer response:** NoBullst1t,
Sorry for the inconvenience. I am late in replying. 
"Please Select Timer and Alert" is displayed, all three timers and two alerts must be non-zero seconds. (even if you have disabled the Water and Rest timers).

If the problem is still not resolved, please open the iOS application and tell us about the specific bug using the form, as it contains a critical bug. If you can submit it with an image, I will be able to respond more quickly.
I will respond with sincerity, so please, please, please, please!

### 5/5 — Awesome

*2023-02-23, version 1.1.0*

Very handy companion for all my sauna trips!

### 1/5 — I don’t mind to pay for something that works

*2023-02-23, version 1.1.0*

This is an paying app and it is not intuitive at all. The app it’s pretty obsolete on iPhone and you can’t find it easily on your iWatch. I don’t really know if I can use it even after pay for it. If you need to watch a tutorial to find and use an app there is something wrong. Use your iPhone timer is better.

### 3/5 — Limited time setting don’t make sense

*2023-01-20*

The app is okay but limiting time to 20 minutes seems short sighted. Infrared saunas run at lower temperature and use may be longer. Limiting time to 60 or 99 minutes would make more sense.  Also, there should be options to skip or not display a cold plunge or cool down. Some just want to track the sauna. 

I guess it only cost me $4 to learn this lesson.

Keep working on it and improve it and I’m sure to look it over again.

**Developer response:** Dear PSroHNY, Thanks for the meaningful review to improve SaunaTime app.

Thank you for sharing your knowledge of infrared saunas! From the reviews, I noticed that a certain number of users who purchase this app use infrared saunas. I am happy to hear users' opinions through reviews like this, and it motivates me to improve the SaunaTime app.

In the next update, I would like to give priority to extending the setting time.

I have also received requests to skip the cold plunge and cool down and track only the sauna. I plan to improve this feature in a future update. However, please be aware that this update will require major modifications to the app specifications, so it may take some time.

Thank you very much for your kind review. I would like to take this opportunity to inform you of any future updates.

### 4/5 — Good but can be great

*2023-01-14, version 1.0.3*

I really like this app and it does what it claims. However, the cold plunge and rest time are required in order to start the sauna timer. A few changes would make this app great. 

- make cold plunge timer optional
- make rest timer optional
- allow for longer sauna duration timer avocet 12 mins. As an experienced user, I wish to stay in longer. Please do not limit it or maybe increase to 1 hour
