AirCube Home is the companion app for StuckAtPrototype AirCube air quality monitors. Connect and see what is in the air of every room, live, with a week of history in your pocket. There is no cloud, no account, and no subscription. Your data never leaves your home. All connectivity is local. LIVE AIR QUALITY Every AirCube streams temperature, humidity, and VOC readings to your phone every few seconds. AirCube Pro adds true CO2 and ambient light. A calm home screen shows every room at a glance: Good, Elevated, or Ventilate. A WEEK OF HISTORY, NO SERVER AirCube logs conditions around the clock and keeps about 7 days on board. The app syncs that history in seconds and stores it on your phone, where it keeps accumulating past the 7-day window. Scrub through charts, spot the evening CO2 climb, and compare rooms side by side. ALERTS THAT DO NOT NAG Get a nudge when a room needs ventilating. Alerts fire only when a reading stays above your threshold, repeat at most once an hour, and respect your quiet hours. Thresholds come pre-configured with sensible defaults, and everything is adjustable: levels, timing, frequency, and per-device muting. UNDERSTAND THE NUMBERS Tap any reading for a plain-language explanation: what CO2 levels mean, where VOCs come from, what to do about them. The 0-100 air score is always consistent with the verdict on the card. PRIVATE BY DESIGN No account. No analytics. No trackers. No internet connection at all. Sensor data lives on the cube and on your phone, nowhere else. Export your data as CSV whenever you want it elsewhere.
