How can I keep track of the duration of my sauna session?Updated a month ago

We do not have a brand suggestion for a timer; however, from customer experience, most use their phone (set multiple timers, overall time, etc... with ease), second is the small digital timers, and some choose a mechanical timer for the "No-EMF experience".

There are quite a few kitchen timers on the market and here are two leads:

• This is a cool 3minute hourglass
• Pro model with drop and splash resistance
