Imagine... You see an avalanche, you ski over to the crown and pull out your iPhone. You snap a photo, measure the slope angle and aspect, then record a crown profile, all on your phone. As you ski down the path, you use your phone as GPS to map the slide. When you get to the toe of the slide you send a diagram of the crown and a map of the slide to your colleagues back at the office, then you post it to the Avalanche Lab network to alert everyone else. With Avalanche Lab you can do all that and more. Avalanche Lab was developed out of a desire to easily enter snow and avalanche data in the field, and then electronically share that data. Avalanche Lab uses all those fancy features on your iPhone to make it as easy as possible. It has all the features an avalanche professional would want, and is simple enough to be used by backcountry skiers and even snowboarders. Avalanche Lab includes clinometer, GPS, and compass support so you can accurately measure and mark your field sites. Avalanche Lab is designed to be used in the field, there is no need for a wifi or cell signal. Most inputs are multiple choice to eliminate the need for typing, and the buttons are big for use with cold fingers. Avalanche Lab produces professional quality snow pit diagrams in the standard format, and in a compact format for display on mobile devices, and saves diagrams as an image or PDF file. Other export formats include KML maps of avalanches, CAAML xml, and SnowPilot format. Avalanche Lab can also import CAAML v5 snow profiles so you can load data from other software for viewing in the field. https://avalanchelab.org/wp-content/uploads/2021/02/Terms-of-Use.pdf

Read full description

The SailHub app is the companion to use your SailHub wind station, enabling sailing classes to have complete performance data for each boat and show each student where they did best and where they can improve.  Once you set up the wind station on your coaching boat, connect your iOS device to the station's Wifi access point, and start the SailHub app. Now your students can use our Tactiqs® app on their dinghies without any instruments and still have complete performance data including wind information. You can select different group IDs for SailHub so multiple classes in the same area can use only the wind information from their coach. The SailHub app provides you with a synchronized countdown and a messaging service that is connected to all Tactiqs® devices in your group, so keeping your class in sync and on the same drill becomes a breeze.
