fluidbalanceapp.com Observed source

Editorial interest 79/100 Selection signal · not a rating of the site

A free iPhone and Apple Watch app for recording fluid intake and output, then turning a 3–7 day diary into a doctor-readable PDF.

Landing page captured for the 2026-09-16 issue.

Field notes

Entries use preset volumes or a custom amount and retain the time, with an explicit “Not measured” option when volume is unknown. The app calculates daily totals, averages, and night-time trips, then presents the diary as a PDF intended for an appointment. The page also describes a five-week grid, widgets, Apple Watch input, CSV export, and a quiet optional reminder; iPad support is identified as forthcoming.
