Total Connect Comfort is the companion app Resideo Technologies publishes for Honeywell heating and cooling hardware. Its job is narrow and clear: it lets you check and adjust your system from somewhere other than the wall the thermostat is mounted on. The app is for remote monitoring and management of heating and cooling, and that is the whole pitch.
The reason to consider it is that it is free, carries no ads and asks nothing for in-app purchases, so there is no second decision to make once you own compatible equipment. With more than a million installs and a 4.2 average across 90,586 ratings, it is clearly in wide use. What I find most telling is the release date: this has been on Android since January 2012, and the developer shipped an update in November 2025, which suggests a long-running product rather than a short-lived one.
What you can actually do from the app
The core of the experience is seeing your system's state and changing it. You can look at heating and cooling settings, set the indoor temperature you want, and adjust the schedule on thermostats that support scheduling. That last qualifier matters: the developer is explicit that schedule editing depends on the thermostat model, so the app's feature set partly mirrors whatever hardware you have connected.
Beyond temperature, the app reaches into the parts of an HVAC system people usually ignore until something feels off. Fan control is available on supported thermostats, and so are humidifier and dehumidifier settings where the hardware allows it. If you have ever wanted to nudge humidity before guests arrive or run the fan without changing the setpoint, that is the kind of adjustment this app is built for.
The developer also notes that the app upgrades itself to new features as they arrive, which means the version you install is not the version you keep. For a piece of home infrastructure, that is usually welcome.
Weather, sensors and the view outside
A five-day weather forecast sits alongside your system controls, which is a sensible pairing: knowing what the week looks like outside is half the reason anyone touches a thermostat. If you have an outdoor sensor, the app also shows outdoor temperature and humidity, so the indoor and outdoor readings can be read together rather than guessed at.
This is the part of the app that feels most like a convenience rather than a necessity, and I would treat it that way. It does not replace a weather service, and it does not claim to. It simply means one less app to open when you are deciding whether to adjust anything.
The outdoor readings depend entirely on having that sensor in place, so the value of this section scales with what you have installed.
Alerts and managing more than one property
Thermostat alerts cover high and low temperature conditions, which is the feature I would weigh most heavily if a property is sometimes empty. A heating failure in an unoccupied house is expensive; a notification that the temperature has fallen below a threshold is the difference between a repair bill and a much larger one.
The app also handles more than one thermostat and more than one registered location. That is what makes it plausible for a small business owner with a shop and a home, or for someone overseeing a rental, without switching between accounts or tools. The developer frames it as serving homeowners and business owners alike, and the multi-location support is the concrete reason that claim holds up.
Nothing here is complicated, and that is the point. It is an app for checking on and adjusting equipment you already own.
What the app needs before it does anything
This is not a standalone smart-home app, and the requirements are worth reading before you install. It works with Honeywell Wi-Fi thermostats. For Prestige, Prestige IAQ, Wireless FocusPRO and EConnect Comfort Systems, it only works in conjunction with Honeywell's Internet Gateway. Without compatible hardware or that gateway, the app has nothing to talk to.
The developer does offer a Demo Mode, which lets you look around before buying a thermostat. That is a thoughtful touch for anyone weighing a purchase, and it is the sensible way to decide whether the interface suits you.
The other trade-off is feature parity. Schedules, fan control, and humidifier or dehumidifier settings each appear only on thermostats that support them, so two people with the same app can have noticeably different experiences. That is a hardware limitation rather than an app flaw, but it shapes what you get.
Who this fits
The natural user is someone who already has compatible Honeywell equipment and wants to stop walking to a thermostat. That includes a household where schedules shift week to week, and a small business where someone wants to confirm the system is running before opening up.
It also suits anyone managing more than one property, since the app is built to hold several thermostats and several registered locations. And it suits the cautious owner who wants high and low temperature alerts rather than a full home-automation platform.
If your interest is broader home control across many brands of devices, this app's scope is heating and cooling, and nothing more. The recent update moved distribution from App Center to Firebase, added Android 15 support and included bug fixes, so the maintenance side looks current.
A focused tool for Honeywell hardware owners
Total Connect Comfort does one job and does not pretend otherwise. It is free, ad-free and free of in-app purchases, it has been maintained for well over a decade, and it covers the practical tasks a thermostat owner actually performs: checking conditions, changing temperature, adjusting schedules where supported, watching humidity and fan settings, and receiving alerts when temperatures move out of range.
The catch is the hardware requirement, which is not really a catch so much as the premise. Feature availability varies by model as well.
If you own that equipment, this is the app the manufacturer intends you to use, and the install numbers suggest plenty of people do. If you are still deciding, Demo Mode is there to help you judge it first.
The short verdict
A free, focused companion app for compatible Honeywell thermostats and gateway-connected systems, best for owners who want remote control and temperature alerts.

Total Connect Comfort: frequently asked questions
Does Total Connect Comfort work with any thermostat?
No. The app is built for Honeywell Wi-Fi thermostats, and for Prestige, Prestige IAQ, Wireless FocusPRO and EConnect Comfort Systems when those are paired with Honeywell's Internet Gateway. Without compatible hardware or the gateway, there is nothing for the app to connect to.
Can I try the app before buying a thermostat?
Yes. The developer includes a Demo Mode that lets you explore the app ahead of a thermostat purchase. It is a reasonable way to see whether the layout and controls match how you like to work before committing to hardware.
What can I change from inside the app?
You can view and change heating and cooling settings, set the indoor temperature, and view and change the schedule on thermostats that support it. Fan control and humidifier or dehumidifier settings are also available where the thermostat supports them. The app also shows a five-day forecast and, with an outdoor sensor, outdoor temperature and humidity.
Does it cost anything to use?
The app is free to download, contains no ads and offers no in-app purchases. The cost sits with the hardware: a compatible thermostat, and an Internet Gateway for the Prestige, Prestige IAQ, Wireless FocusPRO and EConnect Comfort Systems.
Can I manage more than one property with it?
Yes. The app supports multiple smart thermostats and multiple locations when more than one system is registered. That makes it workable for someone overseeing a home and a business premises, or a rental property, from a single app.
