Next step: <p>Here are directions a buyer could take PulseFlow:</p><h3>Immediate (1–3 months)</h3><p><strong>Monetisation activation</strong></p><ol><li data-list="bullet">Re-enable AdMob banner/interstitial (one Gradle dependency)</li><li data-list="bullet">Re-enable <code>PremiumManager.java</code> (already written, just removed for launch)</li><li data-list="bullet">Gate history, trends, and CSV export behind premium</li></ol><h3>Medium-term (3–12 months)</h3><p><strong>New vitals from the same camera</strong></p><p> The rPPG pipeline already captures what's needed:</p><ol><li data-list="bullet"><strong>Respiratory rate</strong> — chest-movement modulation visible in the green channel at 0.1–0.5 Hz</li><li data-list="bullet"><strong>Stress / HRV</strong> — heart rate variability from beat-to-beat intervals in the FFT output</li></ol><p>Each of these is a separate premium feature that uses the same 40-second video capture already in place.</p><p><strong>Backend + user accounts</strong></p><ol><li data-list="bullet">Cloud sync of measurement history</li><li data-list="bullet">Long-term trend dashboards via a web portal</li><li data-list="bullet">Firebase or a lightweight Node.js/Express backend</li></ol><h3>Long-term (12+ months)</h3><p><strong>Clinical / regulated path</strong></p><p> The signal pipeline uses validated rPPG methods (BT.601 chrominance, Hann windowing, stable Butterworth). With IRB-approved clinical validation studies it could pursue FDA 510(k) clearance as a Class II medical device — the same path taken by Withings and AliveCor. This is the highest-value exit but also the most expensive.</p>
