### 4/5 — Great logging app

*2026-08-01, version 1.7*

Only 4 stars because I would like to be able to log  hot tub experiences

### 2/5 — Just a log

*2026-07-04, version 1.7*

If you just want to manually enter on the data from your sauna session this app is for you. That wasn’t what I was looking for. 
No stop watch or timer built in to the app so you have to time your session in other ways then figure out/ remember your start time to log it. No cold plunge option.

### 4/5 — Pretty good but room for improvement

*2026-06-09, version 1.7*

Would love to see a timer feature to start a session at anytime and support with Bluetooth devices to automatically track heart rate like from earbuds.

### 4/5 — Could use some improvements

*2025-11-30, version 1.5.1*

I appreciate the polished interface and the ability to track my time in sauna as workouts that are stored in Apple health. However, why can I not choose a humidity over 40% for a Sauna? I have a traditional steam sauna and cannot choose above 40%?? I’d love to see the ability to save presets for time, temp, and humidity!

### 4/5 — New feature request

*2025-09-26, version 1.5.1*

Enjoy being able to log. It would be nice to start and end a session.

### 2/5 — Meh

*2025-05-20, version 1.5.1*

Wish there was a countdown timer in app so that you could have a session capture your actual time in sauna without needing to set a separate timer. Would also appreciate if it connected with health more cleanly (height/weight, etc to better estimate calories based on heartbeat etc)

### 4/5 — Good but needs watch

*2025-01-27, version 1.5.1*

Good app but needs a watch app and timer and heart rate integration.

### 2/5 — All manual input😞More of a journal

*2024-12-08, version 1.5.1*

I was looking for a sauna app to record sessions. While this app provides a log it could use room for improvement. All input is entered manually. I would like to see more user friendly. For example. Heart Rate should be monitored when I hit a start button for my sauna session. Just how apple provides workout apps. It would record everything once you hit go…

### 4/5 — Needs some tweaking please!

*2024-10-15, version 1.5*

It’s so nice having something to log times but if you could add the ability to look at weekly, monthly, yearly like a fitbit app that would be awesome as you could try and do more temp or time and/or compare weekly/monthly/yearly stats

### 4/5 — Super App aber…

*2024-09-18*

HotLog ist eine super App für alle Saunagänger die es lieben Daten zu Dokument und zu tracken. Das einzige was dieser App dringend fehlt ist eine Apple Watch App mit der ich die Einträge auch von meiner Apple Watch aus starten und tracken kann. Oftmals hat man kein Handy dabei aber die Apple Watch schon. Ob das bei den Temperaturen sinnvoll ist oder nicht sei jetzt mal dahin gestellt. Die Möglichkeit zu haben wäre super.

### 4/5 — Keine Updates bitte…

*2024-08-17*

…welche die ganzen Logs löschen. War letztes Jahr der Fall. Und bessere Exportmöglichkeiten, die auch funktionieren anbieten. Konnte meine Logs nicht mehr wiederherstellen. 

Sonst alles super für den Zweck. Danke!

### 3/5 — Bitte Apple Watch-Support

*2024-03-17*

So leider nicht wirklich zu gebrauchen. Leider zu schnell gekauft.

### 4/5 — Easy to use

*2024-01-02, version 1.4*

Super simple, seamlessly moves into Apple Health. 

Suggestion: I’d love to be able to track my cold plunge time and not just click that I did it. I go from sauna to cold and back again. And I want to know how long I’ve spent in the cold plunge.

### 3/5 — Ok but apple watch app missing

*2023-11-14, version 1.3*

Missing Apple watch app

### 3/5 — No Apple Watch support

*2023-10-18*

Good app, but it was surprise for me that it doesn’t support Apple Watch. Should read notes better next time. I don’t see any needs in it without Apple Watch support.

### 2/5 — Ohne App für die Watch

*2023-09-29*

Eigentlich gefällt mir die App ganz gut, besonders, dass man auch hinzufügen kann, ob ein Aufguss gemacht wurde. Aber leider, leider gibt es keine Ergänzung für die Apple Watch. Und da in den meisten Saunen aus verständlichen Gründen Handys verboten sind, kam ich leider noch nicht dazu, die App zu benutzen. 
Wer also eine private Sauna sein Eigen nennt, der ist hier gut dran. Alle anderen sollten nach einer App schauen, die auch die Watch unterstützt.

## Most critical reviews (10 lowest-rated)

### 1/5 — Useless.

*2024-03-13, version 1.4*

Can’t even get it to work. If it is working what does it do.

### 1/5 — Doesn’t do as advertised waist of $2.99

*2024-01-23*

Doesn’t calculate calories

### 1/5 — Def not worth paying for

*2024-01-18, version 1.4*

I mean you enter your start and end time that’s it and you pay for that?

### 1/5 — Poorly thought about

*2024-01-17, version 1.4*

Says can track ice baths and has a toggle but can’t track temps below 30c in the app which makes no sense.

The temp field should allow for more values to track ice bath temps.

### 1/5 — WASTE OF MONEY

*2024-01-07, version 1.4*

App won’t interface with Apple health like it claims. Not user friendly at all.

### 1/5 — Not worth it.

*2023-07-15*

Not compatible with Apple Watch

### 1/5 — No heart rate

*2023-04-19, version 1.3*

Doesn’t track heart rate 😭

### 1/5 — Disapointing

*2023-02-26, version 1.2*

It s just a notebook without any special insight on your condition and health during sauna time.

### 1/5 — Not worth $1.99

*2023-02-23, version 1.2*

Does not sync with apple health, does not track heart rate or calories burned. It just logs the basic infor. Sauna, 10 minutes, temp 175 and adds a button to say of you did a cold plunge or not. There is no benefit to buying this app. And if you contact support they will not get back to you.

### 1/5 — Misleading

*2023-02-02, version 1.2*

It’s a gloried notepad that cost money

### 5/5 — Good easy app

*2026-06-01, version 1.6*

Very easy to use & nothing like it

### 5/5 — Just what I needed

*2025-11-06, version 1.5.1*

This app is essentially perfect for its stated purpose… Just simply tracking my sauna use: time, temperature. No unnecessary frills.

### 5/5 — Great App!

*2025-07-26, version 1.5.1*

Links your sauna time to Apple Health. Easy to use!

### 5/5 — Mega für Sauna Fans

*2025-02-21*

Tolle App mit schickem Layout und einwandfreier Funktion. Es wäre toll wenn man beim Aufguss Regler auch einen Duft  eintragen könnte :) (statt bei den Notizen)

### 5/5 — Love this app

*2023-11-12, version 1.3*

I record my Sauna session with this app and it performs flawlessly. I am particularly please that it updates my Apple activity app.  My only request would be if you could create another app that records and updates my Apple activity app with similar data for my Cold shower/plunges. To date I cannot find a similar app that would record this information.

### 5/5 — Does exactly what it states

*2023-08-02, version 1.3*

Simple tracking program for Sauna sessions. Has all the needed metrics to track.
Also tracks cold plunges

### 5/5 — Does exactly what it states

*2023-05-23*

Simple tracking program for Sauna sessions.  Has all the needed metrics to track.

### 5/5 — It’s Magical

*2023-05-02, version 1.3*

I track my time in the sauna, and this app magically turns it into exercise minutes!! Perfect for Challenges.

My wife and I use everyday after going into our home sauna!!

Feature request: easily allow one person to track and submit for 2 users or allow easy sharing of the stats so one person can track, then send an easy link with the sauna information to the other. I find one of us will forget to submit, so then it’s a bit of work to go back through older entries to get the other’s updated.

### 5/5 — Great, simple app

*2022-10-26, version 1.2*

Have used for about two years. Straightforward way to track my sauna use. Found no other like it.

### 5/5 — Best sauna app

*2022-06-14, version 1.2*

Love this app. Track my time in sauna without hassle or confusion.
