What is FlowSelfie?
FlowSelfie is a personal monitoring tool for home use. It measures the weight of urine in the container over time and converts that weight change into a flow-rate curve. The companion app displays Qmax (peak flow), average flow, total volume, and voiding duration — and lets you export a PDF report to share with your clinician. FlowSelfie is not certified as a medical device in your region and does not replace clinical examination.
