Most hydration apps tell everyone to drink eight glasses. Hydroguard does the
actual math.
A 180 lb moderately active person at 65°F sea level needs roughly 108 oz of
fluid. The same person under 105°F Tucson sun needs around 146 oz. Hydroguard
pulls your current temperature, humidity, and elevation from MET Norway and
adjusts your daily target accordingly. Log what you drink with three taps.
Watch the ring fill. That's the whole app.
WHAT'S DIFFERENT
• Weather-aware target — not a generic "8 glasses" guess. Heat, humidity, and
altitude all change how much you sweat and respire. Hydroguard accounts for
every one of them.
• Zero tracking. Zero ads. Zero subscriptions. No account to create. No email
required. No analytics SDK, no crash-reporting service, no advertising ID,
and no app-generated or persistent device identifier.…
