Know your
numbers.
PSA Monitor is a simple, private way to track your prostate-specific antigen readings over time — trends, velocity, and doubling time, all in one place.
A clearer picture of
what's changing.
PSA Monitor turns a scattered list of lab results into a story you can actually read — so changes don't sneak up on you.
Trends at a Glance
Every reading plotted on a clean chart with a threshold line, so you can see whether things are steady, drifting up, or spiking.
Velocity & Doubling Time
The metrics your doctor actually cares about, calculated automatically. No spreadsheets. No guesswork.
Threshold Alerts
Add your age and the threshold and velocity limits are set based on current standards. If a new reading crosses the line, PSA Monitor flags it clearly — right at the top of the screen.
Complete History
Every reading, every date, every note in one place. Bring it to your next appointment and have a real conversation instead of digging through paperwork.
Private by Default
Your readings stay on your device. No account to create. No data to leak. Just your health information, where it belongs.
Four taps
to clarity.
Add a reading
Enter the value, the test date, and any notes you want to remember — "baseline," "post-treatment," or anything else.
Set your threshold
The app wiil automatically choose the PSA level and velocity limits that make sense for you and your doctor, based on your age. PSA Monitor handles the math.
Watch the trend
Each new reading updates the chart, the latest value, the average, and velocity. If something crosses your threshold, you'll see it immediately.
Bring it to your appointment
Walk in with a complete history and meaningful numbers — not a shoebox of lab printouts.
PSA Monitor doesn't diagnose anything and it doesn't replace your doctor. It just helps you see your own data clearly — so you can ask better questions.
