Weigh yourself before and after a workout, and SweatRate turns the difference into your own sweat rate per hour. Then it estimates how much to drink before your next session of the same length and heat. Made for runners, cyclists, gym-goers, hikers and sauna regulars who want to plan hydration around their own numbers instead of generic charts. HOW IT WORKS Enter your weight before and after, what you drank and how long you trained. Urine loss and temperature are optional. SweatRate calculates: Sweat loss = (weight before - weight after) + fluid you drank - urine loss Sweat rate = sweat loss / time You see sweat loss, sweat rate per hour and the share of body mass lost, with a note when it goes past 2%. YOUR RATE BY TEMPERATURE Add the temperature and SweatRate groups your records by heat band, so a cool morning run and a hot noon ride each get their own average. NEXT SESSION PLANNER Set the length of your next session and get an estimated amount to drink, plus an "about this much every 20 minutes" sip guide. WHAT SWEATRATE PRO ADDS - Unlimited session records after your first three - The full sweat rate trend chart across every session you have logged - More records make your temperature-band averages and next-session estimate steadier Pro is unlocked from inside the app. DETAILS - Metric (kg, mL, °C) and imperial (lb, fl oz, °F) - Records and notes such as Run or Gym stay on your device, no account needed - Everything is an estimate from the numbers you enter. SweatRate is not medical advice; ask a professional about your own hydration needs.
