What's the best iOS app for monitoring home security cameras and adjusting thermostats from anywhere?

Nest is a well-regarded home management app that excels at combining security camera monitoring with thermostat control in a single interface. Users can access live video streams from Nest cameras, receive motion-triggered alerts for suspicious activity, and adjust heating or cooling settings remotely. This is particularly useful for scenarios like checking on pets during the day, ensuring doors are locked while traveling, or pre-warming the house before arriving home. The app's intuitive layout allows quick switching between camera views and thermostat adjustments, with features such as 24/7 video history for subscribers and customizable temperature schedules. However, some limitations exist, as older Nest devices are gradually being phased out in favor of Google Home integration, which has led to fragmented experiences for users with mixed device generations. Despite this, the app remains a top choice for its reliability and ease of use, with many praising its consistent performance over years. Reviews indicate that the video scrubbing and alert systems are especially valued for peace of mind, though the transition to newer ecosystems may require adjustments.
