Frequently asked questions
proudP is an FDA Class II uroflowmetry medical device that you can use directly on your smartphone. It is designed to measure essential uroflow metrics that urologists use for preliminary assessments of the prostate and urinary system.
The main features of the proudP app include:
Flow Rate (Qmax): Measures how fast or slow your urine stream is.
Voiding Time: Tracks how long it takes to complete urination.
Voided Volume: Calculates the amount of urine you pass.
You can easily check your flow in numbers, get the baseline data of yourself in a discrete setting.
Alongside with the uroflow testing feature, you can also do symptom questionnaires to get a full picture.
Also, all the test results can be shared with your care team through the app if you'd like to do so.
Install proudP app
You can download the app from Apple AppStore or Google PlayStore.
No extra hardware is required for the measurements, but just your phone.

Urine flow test (also known as uroflow test, or uroflowmetry) is a simple, non-invasive test that measures how fast and how much urine flows when a person urinates.
What it measures
Flow rate (Qmax): how fast urine comes out (mL/sec)
Average flow
Total voided volume
Voiding time
Flow curve shape
How it works
Traditionally, you urinate into a special device that records the flow over time. There are no catheters or needles involved.
proudP enables patients to measure their urine flow naturally at home in a private setting using only a smartphone. By leveraging acoustic AI/DL technology, proudP gives the convenience and discreet way of testing uroflow at home. You can repeat tests over time without visiting the clinic, generate longitudinal data that better reflects everyday urinary function and support proactive action, post-operative monitoring, and remote follow-up.
Why urologists use it
Uroflow helps find
Bladder outlet obstruction (e.g., enlarged prostate/BPH)
Urethral stricture
Weak bladder muscle
Post-operative recovery after prostate or urethral treatment
Lower urinary tract symptoms (LUTS) like weak stream, hesitancy, or frequent urination

proudP measures urine flow using just a smartphone, no extra hardware.
When you urinate, proudP captures the sound using the smartphone’s microphone. And our proprietary and patented AI/DL model turns that sound into uroflow parameters, including:
Peak flow rate (Qmax)
Average flow rate
Voiding time
Flow pattern (curve shape)
Step-by-step
1) Open the proudP app
2) Place the smartphone nearby
3) Hit the START button to record
4) Empty your bladder naturally
5) Tap the FINISH button
Results are displayed instantly.
A uroflow test is useful for anyone with urinary symptoms or conditions that affect urine flow, and for people who need objective monitoring over time.
People who should take a uroflow test
1. Men with lower urinary tract symptoms (LUTS)
Weak or slow urine stream
Hesitancy or straining
Stop-and-go (intermittent) flow
Feeling of incomplete emptying
Frequent urination or urgency
Waking up at night to urinate (nocturia)
2. Men with prostate-related conditions
Benign prostatic hyperplasia (BPH)
Enlarged prostate under observation
Rising symptom scores (e.g., IPSS)
3. Post-operative urology patients
After TURP, HoLEP, prostatectomy
After urethral stricture repair (urethroplasty, dilation)
To monitor recovery and detect complications early
4. Men who's already on or starting treatment
Before and after medications for BPH
To objectively assess treatment response
5. Men in need for longitudinal or remote monitoring
Symptoms that fluctuate
Patients who struggle with frequent clinic visits
Those transitioning follow-up care to home
7. Men at risk of urethral obstruction
History of urethral stricture
Prior catheterization or instrumentation
Pelvic or urethral trauma
8. Men with bladder dysfunction
Suspected weak bladder muscle (detrusor underactivity)
Neurogenic bladder (as part of monitoring)
No, all you need is your phone.
