Still can’t scroll to save changes to comfort profiles. I can’t wait until all these remedial code tappers are replaced with AI. UPDATE: Still garbage. Still can’t update the comfort profile because the app doesn’t scroll and the button to save is below the bottom margin. I can drag the screen and see it like an oasis in the desert, but I can’t touch it. Can’t wait until AI takes all their jobs. UPDATE: Still junk. Can’t adjust the schedules because they haven’t figured out not all phones are the size of tablets and I can’t scroll up the page to save/update. UPDATE: Still utter garbage. You can’t even turn the system on off, change, or even look at the schedule. You have to slide the screen up to reach the controls, but it doesn’t stay, so you can tap them. The last update claimed to enhance the UI, but there’s no appreciable change. It’s inexcusable that they just trashed a wonderful, intuitive, extremely useful app for what feels like the work of the CEO’s nephew who took a class. ________ Because Carrier discontinued the thermostat their otherwise excellent app supported, when Apple made changes they appear to have completely deprioritized providing a useful update for it. Left us all out in the cold, as it were. They kept saying they working hard, but every other app I have, from the remedial to the complex figured it out. I guess they’re regretting making a thermostat with such useful and staying power that they gave to keep supporting it, but that’s their job. They can’t even manage to change the OLD pictures from the app they broke. I am seriously thinking about getting a new smart thermostat and seriously determined that it never again come from Carrier OR Honeywell, who coincidentally acquired it in the summer of 2024. ### 1/5 — Used to be three star, now one *2026-04-22, version 2.22.2* Stopped updating. Needs a basic refresh screen pull down mechanism if it won’t show accurate temperature set numbers on its own. Why not ensure both work. ### 1/5 — terrible *2026-03-19, version 2.22.2* Can’t open this iPad with my new iPhone plus getting all kinds of security pop-up saying carrier website is not secure app that does work on my old iPad. Temperature goes all the way down and all the way up whenever it feels like it. ### 1/5 — Disappointing *2026-02-17* UPDATE: Still garbage.

I updated the app. Do not do this … they deleted all the scheduling for air circulation! ### 1/5 — AWFUL app *2026-01-20, version 2.22.2* This app used to work fine, and now it’s bugged for the second time. You can’t change the temperature to what you need. It will only go up by 1 degree, and doesn’t let you do half degrees even though it’s an option. So sick of this app that I’m switching to an ecobee unit. Carrier needs some new app developers ### 1/5 — Terrible.. *2025-12-24, version 2.22.1* When downloading and opening, it goes into the Log In with email. There was no Registration! I registered on the Carrier website and the app does not recognize my email/pw. Can’t register the devices to operate. Customer service line is terrible as well! Get it together Carrier! ### 1/5 — Impossible to use *2025-12-22, version 2.22.0* This app “partially” works…just enough to screw up my heat and AC. scheduled. Cannot Cartier’s idea of a thermostat driven schedule…. So basically I have to manually play with my two thermostats (2 zones) EVERY DAY - and MULTIPLE TIMES to control my house heating and AC. The dealer keeps sending idiots out who don’t know anything about the thermostats they originally installed. Carrier is turning out to be a pile of s—t. ### 1/5 — iOS13 *2025-12-21, version 2.22.0* Was working until we updated the iOS and now it crashes. No update in two years is showing very poor support! Updated and worked for another year now the latest update and it will not work again ### 1/5 — Bugs not fixed, AGAIN. *2025-12-05, version 2.22.0* Still not able to set the temperature. It always goes .5° low/high then the Set temperature. ## Frequently asked questions about Carrier® Côr™ Thermostat ### What does the Carrier Côr Thermostat app do?
