Pilot study of the usability and functionality of a smart ph meter and a mobile medical application for urine ph monitoring.

Objectives: Portable pH meters are robust and reliable tools for measuring urinary pH bypatients at home. This study evaluated the usability of a prototype smart Lit-Control® pH Meter and an associated mobile medical app, with the aim of identifying possible design and functionality issues along with usability problems among non-expert voluntary users.

Matherials And Methods: Twenty-one individuals of both genders, between 26 and 61 years old, tested the dyad pH meter/app for 14 days (three readings per day).
