ColdSwim: Open Water Log
Log open water and cold water swims with water temperature and acclimatisation
About this app
Log every dip, watch yourself acclimatise.
ColdSwim is a journal for open water and cold water swimming, built with safety at the centre rather than bravado.
SESSIONS
• Date, place, water temperature, air temperature, duration and optional distance
• Skins, wetsuit or shorty
• Conditions: waves, current, wind and visibility
• How you felt afterwards
TIMER
A simple session timer with a gentle prompt based on the limit you set for yourself.
ACCLIMATISATION CURVE
Water temperature plotted against session duration across the year, so you can see your own adaptation from summer to winter. If your duration climbs quickly as temperature drops, ColdSwim shows a gentle safety note — never a challenge.
SWIM SPOT BOOK
Your own places with access, parking, tide or current notes and photos, exportable as text to share within your swim group.
MORE

Never swim alone. Know the signs of cold shock and warm up gradually.
