What’s New Version 1.7
Custom Sauna Types
You can now create your own sauna types and track sessions your way. Add favorites like Biosauna, Crystal Sauna, or any custom sauna experience.
Description
There’s something uniquely satisfying about stepping into a hot sauna, steam bath, or infrared room and leaving feeling refreshed, relaxed, and recharged. Beyond relaxation, regular sauna sessions may also offer a range of health and wellness benefits.
HotLog is your personal companion for tracking sauna, steam bath, infrared and cold plunge sessions. Easily record all the details that matter, including:
• Sauna Type
• Temperature
• Humidity
• Duration
• Aufguss Sessions
• Cold Showers & Cold Plunges
Build a complete history of your sessions and gain valuable insights into your habits with statistics and trends. See how often you sauna, track your progress over time, and stay motivated to maintain your routine. For an even more complete wellness picture, HotLog can automatically save your sessions as workouts in Apple Health.
Whether you're an occasional sauna visitor or a dedicated enthusiast, HotLog helps you get more out of every session.

Build 880445958v1.62025-12-18 13:49:21
Finally adjusted the UI to iOS 26 and fixed some warnings and bugs under the hood.
Build 870865694v1.5.12024-12-05 16:28:46
Fixed some small bugs you probably haven't even noticed :)
Build 869385104v1.52024-10-01 11:56:08
Your Sessions are now saved in iCloud, if you're logged in
Build 862339972v1.42023-12-26 17:14:18
Import from CSV is now available in the app settings.
Build 855809979v1.32023-04-12 08:00:34
This update makes the app work with all the beautiful benefits of the lates iOS version (hey, better late than never) and adds some of the many requested features.
NEW:
* Heart rate: you can add your heart rate to each session and also see the average value in the stats.
* Average break time: in the stats you now see the averag time you spend outside the sauna between sessions on the same day.
* Calories label: the calories you'll earn in the Apple Health app are displayed at the very bottom of a session's details page.
Build 831385103v1.22019-09-30 22:00:15
This is a very geeky update. While sweating in the office instead of the sauna (thanks global warming), we got soaked into Apple's WWDC Videos and tried out a lot of stuff.
ADDED:
* Calories: you now earn the calories of a brisk walk for your sweating. This will be added to Apple Health.
UPDATED:
* Darkmode: if you got iOS13 and use Darkmode, the app (and its illustrations) will do too.
* Accessibility: we're using a lot of iOS13 features (e.g. SFSymbols) to give an improved experience for larger fonts.
* Rounded font: we finally use a rounded font on large numbers. Now the app looks even smoother.
* Settings icons: since the new Facebook logo is round we also made the rest of the icons in the settings round. Because we can.
* Space: we managed to reduce the size of the images even further so the app takes up even less space on your phone.
FIXED:
* A crash when you scrolled back a year in the week view and tapped a day from September 2018 - now that it's September 2019.
Build 831148786v1.1.12019-05-01 11:36:21
We are releasing an update every 2nd month, and this is our second update in total - woohoo! This time it's only minor update with a few small changes, hence the "1.1.1."
ADDED:
* URL scheme capability: if you click a "hotlog://" link, the app will open - tadaaa! That makes it easier for us to develop the sharing feature #SpoilerAlert
UPDATED:
* Usability improvement: when you change the sauna type, the controls below will adjust to what you entered the last time for that sauna type.
* CSV format update: changed the structure to show temperature and time units separately - preparing the CSV import feature here #SpoilerAlert
FIXED:
* Fixed a glitch when navigating to Stats, then filtering and scrolling down, then switching to Sessions and then switching back to Stats #WeLoveOurTesters
* Moved the top border of a section header into the background, so it's not striking through the text anymore when scrolling very slowly and veeery observingly.
Build 829636663v1.12019-03-05 15:49:54
This is our very first update after the initial launch in December 2018. Wohoooo!
ADDED:
* Illustrations: now with 12 (instead of 1) gorgeous illustrations - one for each month of the year
* Stickers: you can now use our illustrations in iMessage
* Export: you can now export all session data as CSV in the settings
* First day of the week: you now got the ability to change the first day of the week in the settings #weneededthat
* Rating: the app now will ask you to rate it. Obey! #justkidding #pleaserateus
CHANGED:
* Plunge: Seems like "cold baths" are actually called "cold plunges" - excuese my Genglish (= German version of English)
* Aufguss: We also did not know that an "Aufguss" is called "Aufguss" even outside of the German-speaking countries. So we call that switch now "Aufguss" instead of "Infusion".
* Longer sessions: Some of you really spend a long, long time in the sauna. That's why we increased the maximum duration to 120 minutes.
* Animations: Somebody said that the opening animation of the temperature picker made him dizzy and we don't want him to feel dizzy. So we removed this feature we've been working on hard. #justkidding #itwasabug
FIXED:
* A crash when changing the humidity to "--"
If you have any feature requests just send them to support@hotlog.app - we're happy to discuss every idea!
