TextMeAvy vs Going Blue

Use the TextMeAvy app to request and visualize avalanche forecasts when in the backcountry.

Going Blue is an expedition weather app designed specifically for satellite messengers. It was built for a Denali ski expedition with one goal: to get you all the weather information you would have at home, wherever you are. Going Blue uses a custom codec to pack hundreds of forecast data points into a single message that can be sent over SMS, Garmin inReach, ZOLEO, or iPhone satellite messaging. How it works 1. Build a forecast request in the app. Choose the location, model, and variables that you care about. 2. Send the forecast request to Going Blue via the internet, SMS, Garmin inReach, ZOLEO, or iPhone satellite messaging. 3. Receive an encoded message from Going Blue. Paste it into the app to see a detailed forecast. Features - Satellite ready: Get forecasts anywhere in the world, without cell reception. Works with Garmin inReach, ZOLEO, and iPhone satellite messaging. - Hundreds of data points per message: Uses custom compression optimized for weather data to fit a detailed weather forecast into a single message. - 30+ weather models: Forecasts from high-resolution models like HRRR (3km), HRDPS (2.5km), ICON-D2 (2km), and MET Norway (1km). Automatically chooses the best model for your location. - Detailed cloud cover: See up to 10 levels in the atmosphere to differentiate between high clouds, valley fog, and whiteout conditions. - Mountain forecasts: Pressure-level winds and freezing level for high-altitude mountaineering. - Air quality: Plan around wildfire smoke and other pollution with AQI forecasts. - Model agreement: See how well the forecast agrees with models from NOAA, ECMWF, ECCC, and DWD. - Works offline: All forecasts are saved on your device for comparing multiple models and past forecasts while offline. - Private: Going Blue requires no account and does not store your name, email, or phone number.
