## What is E4 Field Notes?

The E4 Field Notes app makes it easy to record field inspection data about invasive grasses, insects, diseases, weather damage, crop deficiencies and more. When inspection details are recorded in a consistent manner over multiple trips to a field (e.g. pre- and post-herbicide application), users can clearly and precisely measure the advancement or suppression of problems.

E4 Field Notes is used in conjunction with E4 Crop Intelligence™, a cloud-based precision ag support platform that integrates services and technology into one cohesive solution.  The E4 Field Notes app syncs with E4 Crop Intelligence™: it downloads key information about fields marked for inspection (seed types, pre- and post-emerge applications, accumulated growing degree days, and much more), and, in turn, uploads inspection data to facilitate subsequent crop planning.  The app is designed for recording inspection data real-time in the field, and most features can be used with or without Internet connectivity (synchronization can be done anytime an Internet connection becomes available).

Features include:

- Easy-to-access field data (seed types, application details, weather data, etc.)
- Inspection trip metadata (date of inspection, start/end time, weather, temp, etc.)
- Tap-to-select observation details about invasive grasses, insects, diseases, weather damage and more
- Free-form text notes
- One-touch reproduction of observations from previous trips

## Key features
