Open Air Field Guide

Open Air Field Guide is a quiet companion for life outside — built to work fully offline, with no location access and no internet required.

Whether you are heading out for a run, a ride, a walk, a picnic or an evening under the stars, the app offers clear reference material to help you feel prepared. Explore practical notes on outdoor activities, seasonal guidance, clothing suggestions by temperature, and a simple week planner to keep your plans in one place.

The sky section brings together useful reference points such as UV levels, air quality, humidity, wind and moon phases — presented as a handbook, not a live forecast. Everything stays on your device, so you can open the guide whenever you need it, even far from signal.

Open Air Field Guide is designed for people who enjoy the outdoors at their own pace: thoughtful, unhurried, and always ready when you are.
