PhenomApp provides a new method for collecting plant phenotypes in the field using tablets and smart phones. The application is used by plant breeders, agronomists and scientists to record plants' observations in the field (may be it open-field, greenhouse, nursery etc). PhenomApp boosts efficiency and productivity of collecting and characterizing plants data in the field. It replaces the traditional method of pen and paper, saving much time, reducing typing errors, connecting images to traits data and allow browsing previous information for better decisions making. This app is not meant to be used as a stand alone, but rather connected to a database.
