DropPulse: Hydration Science

DropPulse measures your hydration instead of guessing it.

Most hydration apps multiply your weight by a number and remind you to drink. DropPulse runs the actual field protocols: a sweat rate test based on the ACSM position stand, urine tone tracking on an 8-step scale, and a daily target that moves with your workouts, the weather and your measured sweat losses.

SWEAT RATE TEST
Weigh in before and after exercise, then enter duration, weather and fluid intake. DropPulse computes your individual sweat rate in ml/h, stores every test and charts your 30-day median.

URINE TONE TRACKING
Log tone in seconds. The chart plots your daily median and daily range against your water intake, so you see both together. The app tells you when you are likely under-hydrated; it never claims you are well hydrated, because self-assessment cannot prove that.

LIVING DAILY GOAL
Your target adjusts for logged workouts, hot days and your measured sweat rate, with safety caps between 1500 and 4000 ml per day.

ELECTROLYTES
Track sodium, potassium and magnesium against a sweat sodium profile you select yourself, because sodium loss varies from 10 to 90 mmol/L between people and cannot be derived from body size.

BEVERAGE HYDRATION INDEX
A catalog of 26 drinks with hydration factors based on Maughan et al. 2016, not folklore. A coffee and a glass of water do not count identically.

KIDNEY STONE PREVENTION MODE
An optional target based on the AUA/EAU recommendation of at least 2.5 L of urine output per day.

EVERY CLAIM IS CITED
32 medical sources from Mayo Clinic, CDC, Harvard, Cleveland Clinic and PubMed, collected in a Sources screen inside the app.

ALSO INCLUDED
One-tap logging, custom drinks and cups, weight and workout logs, streaks, achievements, history and statistics, reminders timed between the hours you wake and sleep, a home screen widget, and offline use with optional cloud backup.

IN YOUR LANGUAGE
Fully localized in English, Portuguese (Brazil), Spanish, French, German, Chinese, Hindi, Arabic, Russian and Bengali.
