Measure your urine flow at home
FlowSelfie connects to your phone over Bluetooth and records your flow curve, peak flow rate, total volume, and voiding duration — so you can track changes over time.
What FlowSelfie measures
Three key parameters — recorded automatically during each voiding session.
Qmax
Peak flow rate (ml/s)
The maximum speed your urine reaches during a measurement.
Volume
Total volume (ml)
Total amount of urine voided per session, calculated from sensor weight readings.
Duration
Voiding time (s)
How long the active flow lasted, measured from first to last detected drop.
How it works
Three steps from setup to result.
-
Position
Place FlowSelfie on a flat surface and start a session in the app.
-
Measure
The strain-gauge sensor records weight changes during voiding.
-
Read
Your phone receives the result over Bluetooth and draws a flow curve.
Understanding your flow curve
Uroflow curves can reveal patterns worth discussing with your clinician. FlowSelfie records the full curve so you can share it as a PDF.
Bell-shaped
Normal — symmetric smooth curve with a rapid rise and gradual fall.
Plateau
Possible obstruction — a sustained low-flow phase, sometimes seen with prostate enlargement or stricture.
Staccato
Possible dyssynergia — interrupted flow with step-like drops.

Companion apps
FlowSelfie pairs with two apps — one purpose-built, one for broader symptom tracking.
FlowSelfie
Real-time uroflow on your phone
Pair over Bluetooth, view your flow curve live, browse your history, and export results as a PDF to share with your clinician.
BladderDiary
Urinary diary and fluid balance log
BladderDiary is a urinary diary and fluid balance log — track voiding, intake, and FlowSelfie measurements together for a full picture of your bladder health.
Common questions
Is FlowSelfie a medical device?
FlowSelfie is a personal monitoring tool. It is not certified as a medical device in your region and does not replace clinical examination. The device measures urine flow at home so you can track changes over time and share readings with your clinician.
How accurate is FlowSelfie compared to a clinic uroflowmeter?
FlowSelfie uses a strain-gauge weight sensor and reports peak flow within ±2% and volume within ±1 ml. Real-world accuracy depends on factors like container alignment, posture, and stream geometry — different from a clinic device but comparable for home tracking purposes.
Does it work without internet?
Yes. Bluetooth pairing and on-device memory let you measure and view results entirely offline. Internet is only needed if you choose to sync to the cloud or share results.
