Alarm.com is the mobile side of a monitored security setup, published by Alarm.com Mobile. It puts the parts of a property's security system onto a phone or tablet: the panel itself, cameras, locks, lights and more, gathered into one place rather than scattered across separate apps. The reason to consider it is simple enough. If your home or business already runs on Alarm.com hardware, this is the app that lets you watch and control it from wherever you happen to be.
The app is free to download, carries no ads and offers no in-app purchases, which fits a service that is paid for through a security plan rather than through the app itself. It has been on Google Play since April 2010 and currently sits at a 4.1 average from more than 38,000 ratings, with over a million installs. That history tells you something about the kind of product this is: an established companion app for a hardware ecosystem, not a standalone gadget you can pick up and use on its own.
What the app actually controls
The core of the experience is remote control of a security panel. From the app you can arm or disarm the system, manage locks and lights, and generally keep an eye on a property without being there. Alerts are the other half of that: the system tells you when people come and go, or when something unexpected happens, so the app becomes less about checking in constantly and more about being told when checking in matters.
Video sits alongside those controls. The app shows live feeds and recorded clips from indoor and outdoor cameras, and you can narrow the alerts so that only certain activity triggers a notification rather than every passing car or swaying branch. For a doorbell camera, the app brings the conversation and the door lock onto the same screen, so answering a visitor and letting them in happens in one place instead of two.
Scenes are the piece that ties the rest together. A single command can set off several devices at once, which is the difference between a security app you open to check on things and one that runs a routine for you. The developer frames the whole package as a way to automate daily security tasks, and the Scenes feature is where that idea lives.
Built for more than one property
Business use gets its own set of features, and they are more specific than the home side. An operator can arm or disarm panels across several locations from the app, which matters if you are responsible for more than one site and do not want to juggle separate logins or a desktop. Alerts can flag a store opening later than it should, or an employee entering an area they are not supposed to be in.
Access control is handled through the same doorbell screen used at home: staff or visitors can be buzzed through access-controlled doors from the app. Lights, locks and thermostats can be automated on a schedule or on demand, and the app tracks access across multiple properties so there is a record of who went where.
The most consequential business feature is alarm response. When an alarm event occurs, the app is the place from which you respond and alert emergency personnel. That is a serious responsibility to put in a phone app, and it explains why the developer ties the app so tightly to a monitored service plan rather than offering it as a standalone tool.
What you need before any of this works
The developer says you need an Alarm.com service plan and a system that works with it. This is not an app you install and then decide what to connect to it. The hardware and the plan come first, and the app is the interface on top. Feature availability also varies depending on the system, the equipment installed and the plan you are on, so two people with the same app can see different things.
I would treat that as the central trade-off rather than a flaw. The app is free, but the ecosystem behind it is not, and the breadth of what you can do here is bounded by what you have bought and had installed. Someone with a basic panel and no cameras will find a much thinner app than someone with doorbell video, smart locks and a full sensor setup.
The other thing worth setting expectations around is that this is a companion to a service, not a replacement for one. The developer describes an all-in-one app for a connected, protected property, and that is accurate within its own world. It is not a general-purpose smart home hub that will adopt whatever devices you already own.
Suited to a monitored setup, not a casual one
The people who will get the most from this app are those who have already committed to an Alarm.com system: a homeowner with cameras, locks and a panel, or a business operator responsible for one or more premises with access control and alarm monitoring. For them, the value is consolidation. Everything from arming the panel to answering the doorbell to responding to an alarm sits in one app, and the daily routine can be reduced to a Scene or two.
It also suits anyone who wants alerts rather than constant monitoring. The emphasis on intelligent notifications and filtered video alerts points to a design where the app tells you what happened and lets you decide whether to look. That is a calmer way to run security than watching camera feeds on a loop.
For someone without the underlying system or plan, the app has nothing to offer. That is not a shortcoming in the app so much as the nature of what it is: the mobile face of a specific security platform, and only useful once that platform is in place.
The verdict on Alarm.com
Alarm.com does a focused job well. It gathers panel control, video, doorbell interaction, automation and multi-site management into a single app, and it does so without charging for the app itself or interrupting it with ads. The 4.1 rating and the long stretch since its 2010 release suggest a product that has been maintained and refined rather than left to sit.
The catch is the entry requirement. A compatible system and an interactive service plan are not optional extras; they are the foundation, and the features you see depend on the equipment and plan you have. If that describes your setup, this app is the natural way to run it from your phone. If it does not, there is nothing here to install it for.
The short verdict
A well-established companion app for Alarm.com systems, useful only if you already have the hardware and service plan behind it.

Alarm.com: frequently asked questions
Can I use Alarm.com without a security system?
No. The developer says you need a system that works with Alarm.com plus a service plan. The app is the mobile interface for that system rather than a standalone security tool. Without the hardware and the plan behind it, there is nothing for the app to control.
What can I control from the app?
You can arm and disarm your security panel, manage locks and lights, and automate devices such as thermostats. Cameras inside and outside the home can also be viewed live or as recordings. Scenes let you activate several devices with a single command.
How does the doorbell camera work in the app?
The app puts the conversation and the door lock on the same screen, so you can speak with a visitor and let them in without switching views. For businesses, the same Doorbell Call screen is used to buzz people through access-controlled doors.
Does it cost anything to use the app?
The app itself is free to download and carries no ads or in-app purchases. The interactive Alarm.com service plan it requires is a separate matter, and feature availability depends on that plan along with your system and equipment.
Can I manage more than one property?
Yes. The business features include arming or disarming panels across multiple locations and tracking access to several properties. You can also set alerts for a store opening late or an employee entering a restricted area.
