Context unifies your health data from Oura, Whoop, Apple Watch, Fitbit, Strava, Withings, Apple Health and more into one powerful dashboard. It also allows you to track what your wearables can’t, see how everything connects, and finally understand what’s actually working in your protocol. The goal is simple: experience more good days by getting real insights from your wearables, biometrics, and daily patterns. Context is private by default and human by design. ALL YOUR HEALTH DATA IN ONE PLACE See your complete health picture across every device and app you use. Connect your Oura ring, Whoop, Apple Watch, and more, and switch wearables without losing your history. No more jumping between six different apps to understand your health. The following metrics sync automatically from your connected wearables and apps, no manual entry needed: sleep, HRV, heart rate, blood oxygen, steps, workouts, weight, body fat, calories, respiratory rate, and more (full list below). Layer in custom annotations for everything else. PLUS, TRACK YOUR FULL CUSTOM HABIT STACK OR PROTOCOL Your health is more than what a wearable measures. Use our custom annotations feature to log things like supplements, peptides, creatine, cold plunges, sauna sessions, contrast therapy, TRT doses, GLP-1 injections, fasting windows, NAD+, acupuncture sessions, meditations, nootropics, cortisol, caffeine timing, energy levels, mood, symptoms, diet, hormone therapy, blood panels, DEXA results, and anything else in your stack or that matters to you - you name it. If it matters to your protocol, Context can track it. DISCOVER WHAT ACTUALLY WORKS Context shows you correlations between your daily choices and your health metrics. Did that cold plunge improve your deep sleep? Is your supplement stack moving your HRV? How is your new protocol affecting your energy and recovery? Over time, see what’s actually driving change. Run your own experiments, and get real answers. CONNECTS WITH: Oura, Whoop, Apple Watch, Fitbit, Strava, WithingsSmart Scale, Apple Health and more. If it connects to Apple Health, it connects to Context. Whether you’re a biohacker, athlete, life optimizer, or someone who believes health decisions should be driven by data, Context was built for you. Stop guessing.

Do you fall asleep watching Reels or YouTube — and wake up to 12% battery? That's not a bad habit. It happens to millions of people every night. Your screen stays on, videos keep streaming, your battery drains, and your data disappears. All while you're completely asleep. Noctis fixes this. Automatically. HOW IT WORKS Activate Night Mode before bed. That's the only step you need to take. Noctis quietly monitors your activity. It watches for the signals that appear right before you fall asleep — you stop scrolling, you stop moving, your phone goes still. When the pattern is clear, Noctis acts. Before locking anything, it sends you a notification: "Are you asleep? Tap to stay awake." If you don't respond within 5 minutes, your selected apps are blocked through Apple's Screen Time. Screen stays dark. Battery stays full. Data stays saved. In the morning, everything unlocks automatically. Your phone is ready when you are. WHAT YOU SAVE EVERY NIGHT Battery — A screen left on overnight can drain up to 40% of your charge. Wake up at 85% instead of 12%. Data — Streaming video uses 400MB per hour. Noctis stops it the moment you fall asleep. Sleep quality — No screen glow. No notification sounds. Deeper, uninterrupted sleep. FEATURES Night Mode One tap to activate. Noctis runs silently and only acts when you're genuinely asleep — never during the day. Two-Step Lock A warning notification always comes first. Tap "I'm Awake" to cancel. Only silence triggers the lock. Adjustable Sensitivity Low, Medium, or High detection speed. You decide how quickly Noctis reacts. Sleep Window Set the hours you sleep. Noctis only monitors during that window. Morning Auto-Unlock Set a wake-up time. Apps unlock automatically so your morning routine is never interrupted. Night History See how many nights you were protected, how much battery you saved, and how much data stayed in your plan. PRIVACY FIRST All sleep detection happens entirely on your device. We never see your usage data, your app selections, or your activity patterns. Nothing leaves your phone. We only receive: an anonymous session ID (no name, no email), and your subscription status through Apple. Want your data deleted? Settings → Delete Account → gone instantly. START YOUR FREE TRIAL 7 days free. No payment required to start. Cancel anytime through the App Store — no forms, no emails. If Noctis saves even one full charge, it pays for itself. Noctis uses Apple's Screen Time framework to restrict apps. Phone calls and SMS are never affected. All detection is fully on-device.

Verdict

The call

Context and Noctis are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
