reproducible and sensitive in Android and iOS platforms. The technology has utility
in resource-limited settings, where trained healthcare professionals are scarce.
While this chapter demonstrated an equipment-free smartphone reader under
controlled conditions, advanced apps need to be developed to automatically com-
pensate for measurement variability due to changes in focus, angle, lighting con-
ditions, shadow effects and sensor type. Additionally, a step forward in this process
is the design of algorithms that process data ef
ciently into actionable information
for the user. The colour conversion method demonstrated in this chapter is not
limited to urinalysis, but is also applicable to other colorimetric assays such as
colloidal gold, latex labels, aqueous tests, as well as emerging technologies such as
holographic sensors [

medically-relevant data to a centralised facility, and it may be used for endemic or
pandemic surveillance. The app will facilitate less expensive laboratory testing in
the developed nations and enable automated readouts of point-of-care diagnostics in
resource-limited settings. However, successful commercialisation of mobile medi-
cal applications will require clinical trials and FDA clearance to ensure patient
safety [
