RASTR vs we4bee
Price, ratings, monetisation and update history for both apps, side by side β with what reviewers say about each.
RASTR
This application digitizes sea turtle research data collection, allowing scientists to log capture, nesting, and product information with precise locations. It helps track data collection sites, monitor conservation efforts, and provides a cloud-based storage solution to safeguard against physical data degradation.
- Log turtle capture data
- Record nesting information
- Track product data
- Map data collection locations
- Monitor conservation efforts
- Cloud-based data storage

Sea turtles live in many of the worldβs oceans and thus, researchers around the world study many different aspects of sea turtle biology. We have designed this app so that researchers can log turtle capture, nesting, or product data and location. By mapping these records, researchers can keep track of data collection locations, capture history, and monitor conservation efforts in areas of interest. Researchers have traditionally used paper data sheets to collect sea turtle information. However, depending on the projects being conducted, there may be several data sheets for one project. These data sheets may be degraded by rain, humidity, or fire. It is our hope that sea turtle researchers will utilize RASTR to help consolidate and supplement physical data sheets, and digitally store their data on a cloud-based system that is not subject to the same degradative effects. Thank you for using RASTR to aid in your data collection. We hope that it will be a useful and enjoyable experience.

The we4bee app enables display of gathered sensor data (including e.g. temperature, humidity, air pressure, acoustics, particulate matter, wind, rain, ...) of all we4bee high-tech beehives worldwide. Share observations, follow one or more beehives, compare data histories and become part of an international research team. Help us better understand the needs of bees and other insects and make an important contribution to environmental protection.
