SmartRent is a free app from the housing technology company SmartRent, listed in the House & Home category on Google Play. It is the resident-facing side of a smart apartment setup: the app that controls the locks, thermostat and sensors already installed in a home rather than a kit you buy and fit yourself. That distinction shapes everything about it, and it is the main reason to consider it.
The pitch is straightforward. You get remote control of your front door and your heating and cooling, a way to hand out temporary entry codes to people who need them, and alerts when something looks wrong, such as a possible water leak.
It has been available since September 2017 and carries a 4.5 average from more than 23,000 ratings, with over 500,000 installs. Those numbers suggest a settled, widely used product rather than a new experiment, though the experience will depend heavily on what hardware is actually in your home.
Doors, codes and knowing who came by
The core of the app is door access. You can lock and unlock your door from anywhere, which is useful when you are already out and realize you did not secure the place, or when someone is waiting outside and you would rather not turn around. The developer also lets you issue unique access codes that are tied to a time window, so a cleaner, a dog walker or a visiting relative can get in during the hours you choose and not outside them.
The activity side is what I would value most in a shared or managed building. The app shows lock activity, so you can review when guests or maintenance staff came by. That turns the lock from a simple remote control into a record you can check after the fact, which matters if you are coordinating with a landlord, a property manager or a service company.
Between the codes and the log, the app is built for households where people come and go on a schedule. If that describes your situation, the combination is more useful than either feature alone: you decide who gets in and when, then you can confirm it happened.
Climate control that pays for itself
Thermostat control is the second pillar. You can adjust the temperature from anywhere, so you are not stuck with whatever setting you left behind when you walked out. Beyond the manual adjustment, the app supports custom schedules, which the developer presents as a way to save money and energy. Running heat or air conditioning only when the home is actually occupied is the obvious use, and a schedule you set once keeps working without you thinking about it.
The app also supports automations, described as a way to simplify daily routines. The idea is that certain actions happen together or at set times rather than one at a time, so the home responds as a system instead of a collection of separate devices.
Voice control rounds this out. The app works with Amazon Alexa and Google Assistant, so if you already have one of those assistants set up, you can issue spoken commands rather than opening the app. That is a convenience rather than a necessity, but it fits the general aim of not having to reach for your phone every time.
Leak alerts and the Ring connection
Two features sit outside the day-to-day routine. The first is leak detection: the app alerts you to possible water leaks in the home. Water damage is one of those problems where early notice makes a real difference, and a phone alert while you are away is more useful than discovering the issue when you get back.
The second is Ring integration. If you have a Ring account, you can link it so that your camera and doorbell activity sits alongside the rest of your home controls instead of in a separate app. The developer frames this as one less app to manage, and that is a fair description of what linking does.
Neither feature is the reason to download the app on its own, but both add weight to it. A resident who already has Ring hardware gets a tidier setup, and anyone with a risk of plumbing trouble gets a warning system that runs in the background.
What you need before it does anything
This is the part worth being clear about before you install. SmartRent is not a standalone smart home product. It controls hardware that is already in the property, so the app is only as capable as the building it is paired with. A home with a compatible lock, thermostat and sensors will give you the full set of features; a home without them will give you very little.
The practical route is to install the app and let it connect to the devices assigned to your unit. Once that connection exists, the app is where you customize your smart home, and the settings and controls are built around that assumption. Recent updates have been minor bug fixes and improvements rather than new capabilities, so the feature set has been stable.
There is no cost to download, no advertising and no in-app purchases. Whatever the app can do for you, it does without a paywall or a subscription attached, which is unusual for this category and worth noting.
Renters in managed buildings get the most from it
The people who will get real value here are residents of apartments and rental homes that have been fitted with SmartRent hardware. For them, the app is the difference between walking to the thermostat and adjusting it from a chair, or between handing out a spare key and sending a code that expires. The lock log is also designed partly around visits from guests and service providers.
It is less compelling for someone in an ordinary house with no connected devices. The app would have nothing to talk to, and the features that make it interesting, remote locking, schedules, codes, leak alerts, all depend on hardware being present. That is not a flaw in the app so much as a description of what it is: a control layer for a specific kind of housing setup.
The 4.5 rating across a large number of reviews suggests that the people using it in those settings are broadly satisfied. The app has been kept current, and the free, ad-free model means there is no ongoing cost to weigh against what it offers.
A control panel worth having if your home is wired for it
SmartRent does one job and does it without charging you: it puts the smart hardware in your home under one roof. Door access with time-bound codes and an activity log, thermostat control with schedules, automations, voice commands through Alexa or Google Assistant, leak alerts and a Ring link cover the practical side of living in a connected property. The app is free, carries no ads and asks nothing for in-app purchases.
My recommendation is simple. If your building or landlord has equipped your home with SmartRent devices, install it, because it is the intended way to use them and its features are genuinely useful for anyone who comes and goes on a schedule or wants warning of a leak. If your home has no such hardware, the app has nothing to control, and the sensible move is to check what is installed before you bother.
The short verdict
A free, capable control app for residents whose homes already have SmartRent locks, thermostats and sensors installed.

SmartRent: frequently asked questions
Do I need smart devices installed in my home to use SmartRent?
Yes. The app controls locks, thermostats and sensors that are already present in the property, so it works with hardware rather than replacing it. A home without compatible devices leaves the app with little to do, while an equipped unit unlocks the full feature set.
Can I let a cleaner or dog walker in without giving them a key?
The app lets you grant unique access codes that are limited to a set period, so a service provider or a relative can enter during the hours you choose. Lock history shows when guests or maintenance staff came by.
Does SmartRent cost anything or show ads?
The app is free to download and contains no advertising. It also offers no in-app purchases, so the features described by the developer are available without spending inside the app.
Can I control the thermostat and set a schedule?
You can adjust the thermostat from anywhere and create custom schedules. Scheduling runs heating or cooling around your routine rather than all day, which can cut energy use and cost.
Does it work with Alexa, Google Assistant or Ring?
Alexa and Google Assistant both work with it for voice control. You can also link a Ring account so camera and doorbell activity sits alongside your other home controls rather than in a separate app.
