CalypsoSpray helps farmers, agronomists, and spraying professionals make better decisions before and during field applications. The app connects to compatible Calypso sensors via Bluetooth and displays real-time environmental data, including wind, temperature, and humidity. This helps users assess whether conditions are suitable for spraying and reduce the risk of drift, product loss, and applications outside recommended ranges. Designed for field use, CalypsoSpray provides a clear, fast, and easy-to-read interface for iPhone and iPad. Key features: - Real-time readings from compatible Calypso sensors. - Wind, temperature, and humidity monitoring. - Clear indicators to assess spraying conditions. - Simple interface designed for outdoor agricultural work. - Direct Bluetooth connection to the sensor. - Compatible with iPhone and iPad. CalypsoSpray is designed to support field decision-making, but it does not replace local regulations, crop protection product instructions, or the professional judgment of the applicator.
