## What is PSA Monitor?

PSA Monitor helps you take an active role in tracking your prostate health. Log your PSA test results, visualize trends over time, and understand what your numbers mean — all in a clean, easy-to-use app that keeps your data private on your device.

Key Features

• Visual Trend Charts — See your PSA history plotted over time with an interactive chart. Tap any point to view the exact reading.

• Age-Based Thresholds — Automatically adjusts PSA reference ranges based on your age (40s: 2.5, 50s: 3.5, 60s: 4.5, 70s: 6.5 ng/mL), so you always know where you stand for your age group.

• PSA Velocity Tracking — Calculates how fast your PSA is changing per year using your recent readings. Get alerted if the rate of change exceeds clinical guidelines.

• Doubling Time Analysis — Uses log-linear regression on your last 18–24 months of data to estimate how quickly your PSA could double — a key metric doctors watch closely.

• Smart Alerts — Receive notifications when your latest reading exceeds your personalized threshold or when your PSA velocity is concerning.

• Detailed History — Browse, edit, and annotate every reading. Add notes from doctor visits to keep everything in one place.

• Built for Accessibility — Full VoiceOver support, color-blind-safe indicators, and audio graph descriptions for charts.

• 100% Private — Your data stays on your device. No accounts, no cloud uploads, no tracking. Period.

PSA Monitor is a personal tracking tool and is not a medical device. Always consult your doctor or healthcare provider to interpret your PSA results and guide your care.
