CDTEC IF pone el monitoreo de tus campos en el teléfono. Revisa en terreno lo que está pasando en cada sector: la humedad del suelo a distintas profundidades, el crecimiento de la planta, la salinidad, la temperatura, el clima y el programa de riego del período. QUÉ PUEDES HACER • Ver el mapa de tu campo con el estado de cada sector de un vistazo. • Seguir la humedad de suelo por profundidad, con tus líneas de gestión de riego. • Medir valores exactos sobre cualquier gráfico y comparar dos momentos. • Revisar el riego del período: eventos, programación y precipitación teórica. • Consultar el informe quincenal del sector y descargarlo en PDF. • Dejar comentarios sobre un punto del gráfico para coordinar con tu equipo. • Entrar con Face ID, sin escribir la contraseña cada vez. PARA QUIÉN ES Para agrónomos, jefes de campo y equipos de operación que necesitan decidir el riego con datos y no con estimaciones, estén donde estén. CDTEC IF es la aplicación móvil del servicio de monitoreo agrícola de CDTEC, utilizado por empresas frutícolas y agroexportadoras en Chile y Perú.

Verdict
The clearest difference is in-app purchases: CDTEC IF at none against 3D Model Viewer's 1. CDTEC IF also leads on update cadence (every 3 days vs weekly). On price, ads, device support and iOS requirement there is nothing between them.
