What’s New Version 1.6.2
Substrata now leads with headaches. Tap to log one from the Dashboard, then watch the patterns build as Substrata pairs each entry with the weather, sleep, and noise around it. Plus a sharper paywall, an honest motion-permission description, and dozens of smaller fixes across the app.
Description
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.
It 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
- No servers. 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 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.

Build 885542671v1.6.12026-05-12 17:22:26
Listing copy and metadata refreshed so it's easier to find Substrata if you're tracking headaches, sleep, or weather-driven symptoms. Recompiled against the latest iOS SDK. No new permissions or features in this update.
Build 885263382v1.6.02026-05-07 16:34:43
New plans: monthly, annual, or one-time lifetime — all with a 7-day free trial on the subscriptions. Existing buyers keep premium access automatically. The paywall now has tier choice and a clear note about Apple Watch when it matters. Local Diagnostics under Settings shows what Substrata counts on your phone, opt-out anytime.
Build 885244952v1.5.02026-05-04 22:01:30
Rebuilt Settings: clearer sections, harmonized status across permissions and live data, and a new explainer for how Substrata handles your data. Restore Purchases is front and center, and you can wipe all your Substrata data in one place. Turning on cycle or intimacy tracking now walks you through the Apple Health permission first. One toggle in Preferences now controls every displayed unit, including temperature.
Build 885140778v1.3.02026-05-01 14:50:05
Substrata now speaks German, French, Italian, Spanish (Latin America), Portuguese (Brazil), Japanese, and British English. Numbers, dates, and units are locale-correct everywhere — including charts, exports, and widgets. AI-generated insight narratives and Siri shortcuts are localized too. Pick a measurement system (Metric, Imperial, or System default) in Settings.
Build 885166536v1.4.02026-05-01 22:18:56
Substrata now offers opt-in period and intimacy logging - both on-device, biometric-gated, and never written to Apple Health. Cycle phase, daily flow, and symptoms add new dimensions to the correlation engine, with a 12-month phase heatmap and period prediction once two cycles are logged. Turn either on individually in Settings → Reproductive Health.

Build 884784561v1.2.02026-04-22 21:20:27
New: every morning, Substrata now scores the room you slept in, not just how you slept.
Sleep Condition Score pairs with your sleep quality on the dashboard so you can read them together. Bedroom noise, temperature, humidity, and pressure stability all feed the score, and a "Bedroom-measured" badge shows when your Watch and phone measured the room directly. Premium adds a 14-night trend, plain-English tips for the nights that scored below comfort, a new Widget line for last night's room, and columns on the CSV and PDF exports for sharing with a clinician.
