Developed by researchers for researchers and their teams, Behayve integrates the recording of behaviors, tracks and surrounding environment, offering insight as you go by displaying real-time maps of tracks and the exact positions where behaviors occur. Used in 1,400+ studies, many for endangered species. Free app, in-app purchases available. With or without Internet or GPS, the app determines precise animal positions on the fly, non-invasively, using compass bearing and range in conjunction with GPS or grid map. CONFIGURABLE Behayve is designed to support a wide range of studies of terrestrial, marine and avian species. You can define your own ethogram, behavior groupings, roles, modifiers, data items, species and more. SAMPLING MODES Choose from focal, scan, behavior or ad-lib sampling, or run them all at once. The implementation is based on Jeanne Altmann’s 'Observational Study of Behavior'. ROLES AND MODIFIERS Multiple roles and multiple modifiers may be configured for any behavior. Behaviors may be instantaneous events or continuous states. A collection of states may be configured to be mutually exclusive. CUSTOM DATA Optionally define your own custom data items. INSIGHT While observing, you can get additional insight by viewing a terrain map of action to date, pinpointing the exact location of behaviors and tracks. Tap on an observation to pop up its associated timestamped data. A predictive function can help locate animals that have gone out of sight. REVIEW AND CORRECTION At any time during observations, or later, you can rapidly review and alter your recorded observations, including your voice notes or comments. Calculated data such as latitude/longitude will be adjusted appropriately. COLLABORATION, STUDENTS AND CITIZEN SCIENCE Behayve facilitates data sharing between team members — colleagues, students or citizen scientists. Merge data from team members at the same or different locations. Your distributed configuration can be locked down to prevent modification. GIS INTEGRATION With no effort, transfer any amount of observational data to GIS systems such as ArcGIS, QGIS and KML-based systems like Google Earth, preserving its structure — this can be an enormous labor saver. View 2D or 3D tracks and behaviors. Click on an observation to display its associated data. Spreadsheet export is also available. Icons for photos can be automatically placed at the position they were taken, even from cameras without GPS. RELIABILITY Your data is retained in a rock-solid onboard database immune from power failure. Structured data can be exported to the safety of the cloud (or to a laptop) and the entire database can be backed up to the cloud or laptop. CODING CONVENIENCE Behayve is intuitive and straightforward to use. Its pocket size is a winner. Automated features make data recording easy, fast and reliable. For example, to record compass bearing and elevation angle, simply position an animal in the crosshairs. To record range, just point and shoot a handheld wireless rangefinder, or enter manually. AERIAL SURVEY OR THEODOLITE Choose from terrestrial, marine or aerial operating modes (Roving 2D, Roving 3D, Theodolite or Aerial). For aerial surveys, simply position an animal in the crosshairs and Behayve records its latitude and longitude. Or enter bearing and azimuth manually. GNSS AND DIFFERENTIAL GPS Via wireless connections, achieve sub-meter positioning accuracy using handheld or fixed units such as the Arrow 100, sensed automatically by Behayve. Or simply rely on the iPhone’s built-in GPS hardware. With GNSS devices, improve positioning accuracy under canopy, harnessing the combined forces of GPS, Glonass, Galileo, Beidou and other satellite constellations. HOOK UP YOUR GEAR At sea, continuously log water temperature and depth wirelessly from the ship’s chartplotter. Talk to us about wireless connection of your own unique devices.

Rilla Forms

Google Forms™ is a simple and great tool for building web forms. With Rilla Forms, it can be used as a powerful and easy to use offline field data collection system. To begin, create a Google Form™ as you normally would and use the Rilla Forms add-on to publish it. This produces a QR code which you can scan. Then you can go into the field and fill in form data as many times as you like and upload it when you are online. For example, suppose you want to capture observations of insects for a school project. The teacher creates the form, and each student scans the QR code on their phone and then fills out the form for each insect they see. When they return to class, they can upload their data and the teacher can immediately see it in Google Sheets™.

Verdict
The clearest difference is in-app purchases: Rilla Forms at none against Behayve's 4. Behayve's advantage is update cadence (every 10 days vs every 5 months) and iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.
