Hey Product Hunt 👋 I built Narelia because I was already wearing an Apple Watch every day and collecting a huge amount of health data, but I kept feeling that most of those numbers lacked context. An HRV value, resting heart rate or sleep score means very little on its own. What interested me was: how does this compare to *my own* normal? That became the main idea behind Narelia. Instead of comparing everyone against the same population ranges, Narelia builds a personal baseline from your Apple Health history and uses it to put readiness, HRV, sleep, stress and recovery into context. I also wanted to build it differently from most health apps from a privacy perspective. There is: • no account • no login • no Narelia server storing your health data The analysis happens directly on your iPhone using data you already have in Apple Health. Another thing I cared about was supporting different generations of Apple Watch instead of designing the experience around only the newest hardware. Narelia adapts the signals it uses depending on what data your watch can actually provide. The beta has already been tested by almost 200 people through TestFlight, and their feedback has helped shape a lot of the app. I’d especially love feedback on how clearly Narelia explains the *why* behind its metrics, not just the final number. Thanks for checking it out.
