Sauna Assistant: Ritual Timer

Turn heat and cold into a ritual. Sauna Assistant guides your home sauna from first round to final rest. Pick a ritual, press start, and let calm audio cues carry you through heat, cold and quiet. Your iPhone stays outside the sauna and plays through your sauna's speakers.
