SensorBlue vs Gustline

The Smart Hygrometer Thermometer is the easiest way to monitor the humidity and temperature conditions affecting the things you are about. Just quickly pair the app with the humidity-temperature sensor. Then you can check the current temp and humidity status of the environment. You can connect more than 100 devices in your app. If you want to use data, you can export your entire history to CSV for analysis. It records the data every 10 mins.

Gustline shows live wind direction and an overnight shelter forecast for wherever you're camping — built to keep working long after you lose signal. WIND, AT A GLANCE A compass-style readout shows current wind direction, speed, and gusts, with a live map underneath so you can see exactly where you are. Scrub the hour-by-hour timeline to see how wind is forecast to shift through the day and overnight. KNOW WHERE TO PITCH YOUR TENT Gustline doesn't just show numbers — it tells you what to do with them. Its overnight shelter advisory calls out the strongest overnight gusts and which direction they're coming from, so you know which side needs a windbreak before you set up camp. WORKS WITH NO SIGNAL Open Gustline once while you still have a connection, and the forecast and map both cache automatically. From then on, everything keeps working in airplane mode — no signal needed once you've arrived. READABLE IN BRIGHT SUN A dark theme built for reading at night, and a light theme built for reading in direct sunlight — switch anytime in Settings. NO ACCOUNTS. NO ADS. NO TRACKING. Gustline doesn't ask you to sign up for anything. There's no advertising and no crash-reporting SDKs, and nothing about you is bought or sold. Your location is used only to fetch the forecast and show your position on the map — see the full privacy policy for exactly what's sent and to whom.
