As answered by people managing https://open-gpt.app/ and PulseCheck.
PulseCheck's answer:
Most camera-based vitals apps show a clean number even when finger movement or bad lighting ruins the reading. PulseCheck calculates a real-time signal confidence score with every measurement, telling you upfront whether the reading is solid or if noise skewed the result.
PulseCheck's answer:
You get smartwatch-level recovery and HRV tracking without needing to buy, charge, or sleep in a wearable. On top of accurate scans, it combines body battery energy scoring, manual vitals logging (BP, glucose, SpO2), doctor-ready exports, and guided recovery programs all in one place.
PulseCheck's answer:
PulseCheck is made for anyone who wants clarity on their health without extra hardware: - People dealing with unexplained fatigue, stress, or burnout who want daily data to validate how they feel. - Individuals managing chronic conditions who need an organized vitals log to share with their doctor. - Biohackers and athletes looking to track baseline recovery and HRV trends. - Anyone who wants wearable-style body insights using only their phone.
PulseCheck's answer:
The goal was simple: make accurate recovery and vitals tracking accessible to anyone with an iPhone. Smartwatches are expensive and often uncomfortable, while existing camera-based pulse apps regularly produce inaccurate, misleading readings without any warning. PulseCheck was created to deliver genuine measurement transparency, giving users reliable biometric feedback they can actually trust.
PulseCheck's answer:
PulseCheck uses iOS camera photoplethysmography (PPG) algorithms to detect micro-vascular blood volume changes via the camera lens and flash. It runs signal-processing filters for noise reduction and confidence scoring, native iOS frameworks (Swift and SwiftUI) for on-device baseline analytics, and AI models to power guided recovery programs and personalized coaching insights.
