Cosy is a portable, wireless thermostat that simplifies heating control using an app. Thanks to the Cosy App, you and your family can control your heating and hot water from anywhere - using your smartphone, tablet or PC. Psst! You’ll need to buy a Cosy system for the app to work. For hot water and twin-zone heating you’ll need to have Cosy set up for this. Please note: you’ll need to update to the newest version of this app to unlock some of our latest (and greatest!) future features – like temperature graphs – more info below. Customised heat settings ----------------------------------- Take your pick of our four heating, then sit back, relax and let Cosy do the rest. Choose from: • Slumber - the temperature you'd like your home to be when you're asleep or away from home. • Comfy - the temperature you'd like it to be when you're at home • Cosy - the warmest temperature setting for when you need a good ol’ heat boost. • Hibernate - keeps your heating off but protects your pipes against frost. Hey presto - no burst pipes! Extra Cosy features: hot water and twin zone ------------------------------------------------------------ It’s now even easier to tailor Cosy to your home’s heating set-up. Cosy can control your hot water as well as multiple heating zones. All heating events - home and water - can be controlled, scheduled and boosted from the app or the Cosy Display. Easy peasy! Psst! You’ll need to have your Cosy wired up for twin zone heating and hot water. Get in touch with our support team cosysupport@geotogether.com for more help. Temperature graphs --------------------------- You’ll soon be able to see your heating data in even more detail. View your home temperature readings and mode change info for the past 30 days. Coming soon to a Cosy App near you… Making comfort affordable ------------------------------------ Stuck in a meeting (groan)? Invited out at the last minute (hooray)? If so, don't waste good heating time when you're not there. Use the app to turn your heating down to help you save on your energy bills. Welcome Home to Cosy feature ------------------------------------------- By connecting a Smart Plug to your Cosy you can schedule your lights, your radio, or even your slow cooker to come on when your heating does. Don't just come home to the warm, come home to Cosy. Schedules to suit your lifestyle ----------------------------------------- Simple to set up, you can create up to seven unique heating profiles for Cosy. So if you regularly do something different every day of the week, Cosy will know exactly what to do. Cosy for all fuels and family members -------------------------------------------------- Now the whole family can download the Cosy App. When someone changes an event it appears in the Activity feed, so you can keep an eye on energy hogs (aka Grandma Jean). Cosy works with gas, oil, LPG and biomass. Who are we? ------------------ Cosy is the result of a lot of brainpower from the team here at geo (Green Energy Options). We're an innovative tech company, based near Cambridge. We’ve been working on energy data since 2006. We’ve already helped many homeowners across the UK turn their houses into Cosy homes. Now, it’s your turn to start coming home to Cosy too!

I’m not interested in fancy graphs or heating timetables devised by NASA, I just want something that turns my heating on and off when I want it to. Remote control is quite a nice addition. Cosy does what I want it to in a simplistic way so I have to give it a 5. -- Lesthefizz, 2024-11-27 ### ***-- "Simple App" Simple app and has a range of functions but quite clunky and dated -- olii42, 2024-11-23 ### *---- "Avoid like the plague" Worked fine for years, now has black text on a black background on the key screen ?? I mean really ??? how utterly idiotic…. Obviously no one checked the app after the last update, oh, and it doesn’t work anymore… only gave one star as there isn’t an option for Zero -- Loza600, 2023-11-12 ### **--- "Terrible app" I’ve just moved into a house which already has this cost device installed. Whilst the concept is good, the app is absolutely terrible! When registering I had to guess which fields needed what information as they were all black with no descriptions, and all the fields that I guess are used to set the profiles etc up are black and formatttd terribly. Please sort your app out! Wish I’d brought my google nest with me from my old house… that’s how an app for smart home heating should be. Dissappointed… will probably get rid of the system at some point. -- Ashwood Phil., 2023-06-29 ### ***-- "Not good if you’re in Dark mode on IPhone" If iPhone is set to dark mode some of the menus are back and difficult to read. Please could you amend this as I have my phone set to dark mode as it’s easier to see things in contrast -and it just doesn’t work in this app. -- miniroof, 2022-12-13 ### *---- "Top worst app -avoid cosy at all costs" Never worked properly since release, seems abandoned by the developers , which is probably a good thing so everyone has to move to a competitor that has a system that works They can’t even change the app so dark mode works…. Incompetency all round I would avoid anything from geo, they are cheap incompetent devices that don’t work -- Shalow, 2022-11-24 ### *---- "Bye Bye Cosy" Hello Nest -- davethevibes77, 2022-11-22 ### **--- "This app has problems" I have used the Cosy app over the years on my iPhone, iPad and Alexa. This winter it has failed on my iPad as it will not accept the password. I also cannot set it up on Alexa for the same reason. Unfortunately despite several messages to and from the developers they still cannot solve the problem which should be very easy to correct. I have never had these problems on any of my other apps. At least it works on my iPhone. Have given up on trying on other devices. Such a shame as the Cosy system has been working well for the many years I’ve had it installed. -- Riverpiper, 2022-11-20 ### *---- "Terrible app goes with a terrible system" My husband and I moved into a home with a Cosy hub installed. It’s is terrible! The app is worse! Wish I could upload screen shots of certain app screens where the text is black, on a black background!! Idiotic! Have to wait for the app to connect to the devices if I haven’t logged on in a while which is a pain and is seems to take forever. I really don’t see how people think it is a good system? -- JennyKRH101, 2022-10-25 [View all Cosy reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Apps Similar to Cosy - [Smart Monitor by Certas Energy](https://apptail.io/app/smart-monitor-by-certas-energy-Ugo/united-kingdom) - [myenvirovent](https://apptail.io/app/myenvirovent-Gkwb/united-kingdom) - [Your Voucher Book](https://apptail.io/app/your-voucher-book-EqLe/united-kingdom) - [Masjid E Ghosia](https://apptail.io/app/masjid-e-ghosia-yaqh/united-kingdom) - [30 Plants Per Week](https://apptail.io/app/30-plants-per-week-ZBTm/united-kingdom) - [Native](https://apptail.io/app/native-JKpp/united-kingdom) - [Solihull Family Hubs](https://apptail.io/app/solihull-family-hubs-VyUq/united-kingdom) - [Time:o:stat](https://apptail.io/app/timeostat-gFSu/united-kingdom) - [habi Smart Home](https://apptail.io/app/habi-smart-home-uFKv/united-kingdom) - [Freedom To Drive](https://apptail.io/app/freedom-to-drive-erkx/united-kingdom) ## Cosy Available In - [United Kingdom](https://apptail.io/app/cosy-fnpj/united-kingdom) - [Germany](https://apptail.io/app/cosy-fnpj/germany) - [Finland](https://apptail.io/app/cosy-fnpj/finland) - [Ireland](https://apptail.io/app/cosy-fnpj/ireland) - [Netherlands](https://apptail.io/app/cosy-fnpj/netherlands) - [Portugal](https://apptail.io/app/cosy-fnpj/portugal) - [Romania](https://apptail.io/app/cosy-fnpj/romania) - [Belgium](https://apptail.io/app/cosy-fnpj/belgium) - [Sweden](https://apptail.io/app/cosy-fnpj/sweden) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
