Substrata vs Kingtide

Wake up tired without knowing why? Headaches that hit out of nowhere? Substrata watches the noise, weather, and air around you, then pairs it with your sleep, heart rate, and HRV — so you can see exactly what's affecting how you feel. The analysis runs entirely on your iPhone using Apple Intelligence. After about two weeks, the on-device correlation engine starts surfacing connections — barometric pressure drops that match your migraine days, bedroom noise that quietly steals your deep sleep, weather patterns that drag down your HRV. Plain-English explanations you could share with your doctor. YOUR SLEEP, EXPLAINED - Sleep Condition Score: how well your bedroom actually treated you (noise, temperature, humidity, pressure stability) - Pairs with HealthKit sleep data + Apple Watch wrist temperature - Hourly, daily, weekly charts with WHO/EPA threshold zones color-coded HEADACHE & SYMPTOM TRIGGERS - Tap to log a headache (migraine, tension, cluster) with severity and notes - After 20-30 logged events, your personal trigger profile starts building - Predictive alerts when conditions match your past headache patterns - Also tracks allergies, mood, joint pain, energy ON-DEVICE INTELLIGENCE - All correlation analysis runs on your iPhone - Weather comes from Apple WeatherKit, using your approximate location - No accounts. No third-party analytics SDKs. - Microphone is not used in production; noise data comes from Apple Watch - Privacy nutrition label: no data collected WHAT YOU GET WITH PREMIUM - Every correlation the engine finds (free tier shows your top one) - Personal headache trigger profile + predictive alerts - AI-generated insight narratives - PDF and CSV export — bring a real report to your doctor - History beyond 30 days Requires iPhone with iOS 26.2 or later and an Apple Intelligence-capable device for AI insights. Apple Watch strongly recommended for environmental noise, HRV, and sleep-stage data; works without a Watch using weather, sleep duration, and headphone audio. Substrata is not a medical device and does not provide medical advice. It explores potential connections between environmental and health data for personal review. Consult a healthcare provider for diagnosis or treatment.

The workout tracker for people whose bodies hurt. Log every set like any tracker. Then tell it what's sore, and every session is rebuilt around it. Bring the routine you already run, from a photo or a Strong or Hevy export, and it's in your week the same day. Most workout apps assume nothing ever hurts. Kingtide is built for the opposite. Log a bad shoulder, a nagging knee, or a lower back that flares up, and every workout from then on is built around it. Not "see a professional and come back." A session you can actually do today. LOG AN INJURY ONCE Mark the area on a body map and say how it feels. Kingtide swaps the movements that aggravate it for ones that don't, and leaves the rest of your session alone. Mark it good again when it settles, and the plan walks you back. YOUR ROUTINE, IN ONE IMPORT Screenshots from Strong or Hevy, a CSV export, a whiteboard, a photo of paper. Kingtide reads it on your phone, keeps your days, your sets, your reps and your weights, and shows you what it read so you can fix anything before it becomes your week. Your leg day stays a leg day. YOUR REHAB PLAN, FOLDED IN Photograph the exercise sheet you were given, by a physio, a PT, a chiro or your doctor. Those exercises are built into your week, so you follow that guidance without dropping your training. Nothing is uploaded to do it. A TRACKER THAT PAYS ATTENTION The runner logs what you actually lifted, not what was planned. Recovered muscle goes up. Still-sore muscle holds the weight and adds a rep. Every number on the progress screen is read back off sessions you really did, so an empty week looks empty. A PLAN THAT BENDS INSTEAD OF BREAKING Short on time, or slept badly? Say so at check-in and today's session reshapes to fit. Training for a sport? Say which, and the week leads with what it asks for. A rough week changes your training instead of ending it. YOUR INJURIES STAY ON THIS PHONE The body map, your pain notes and the routine you imported live on your device, not on a server. Anonymous usage analytics and crash reports are the only things that ever leave, and Profile has a switch that turns those off too. WHAT IT DOESN'T DO No account. No sign-up. No email address. Kingtide is not medical advice and is not a substitute for a doctor or a physical therapist. If something is genuinely injured, go and see one. FREE AND PRO Fourteen full workouts free. Your plan and your logged history stay yours either way. Kingtide Pro removes the session limit and keeps the plan adapting for as long as you train. Kingtide Pro is an auto-renewing subscription, offered monthly or yearly. Payment is charged to your Apple Account at confirmation of purchase.
