Gracias por descargar Lux Meter en tu iPhone. Lamentablemente, Apple no permite acceder al sensor de luz del iPhone, por lo que la aplicación no puede utilizarlo para realizar mediciones como en otras plataformas. Realmente me gustaría que fuera posible y añadiré compatibilidad de inmediato si Apple permite el acceso a este sensor en el futuro. Lamento mucho esta limitación y gracias por tu comprensión. Puedes escribirme directamente a apps@contechity.com. ¡Gracias de nuevo! ### 5/5 — Amazing for beginners *2026-05-07* I’ve been using this app for a few days after getting into analog photography and vintage cameras and it’s been a game changer.
