The Top 4 Home Security System Apps

  • ADT Control App
  • Vivint Smart Home App
  • Frontpoint Mobile App
  • SimpliSafe Home Security App

Each of these multipurpose apps allow customers to sign in at any time from their smartphone and arm, disarm, and monitor their security system from anywhere. However, each has its unique pros and cons.

Proprietary vs Universal Home Security Apps

It’s important to note that there are two types of home security apps, proprietary and universal. Proprietary apps are created by specific home security companies and are designed for controlling their own unique system. The company that owns the app is responsible for all updates, features, and more. The major pro of a proprietary app is that it’s customized for the specific company. The downside is that the quality isn’t always guaranteed like it might be with a universal company that designs standardized apps.

Universal apps are created by companies like Instead of being tailor-made for one particular home security system, they are compatible with a variety of systems. Quality is generally more standardized, but because universal home security apps are not designed with one particular company in mind, features like new smart home compatibility might take longer to access.

ADT Control App

The ADT Control App has an extensive range of home automation controls. It allows you to arm and disarm your system, view your indoor and outdoor camera footage, and even turn off small appliances like coffee pots. If you purchase a more comprehensive package, the app works with Amazon Alexa, which is a rare feature in home security apps.
