I have the same complaint regarding the new app version as other people: without the animations that were present in older versions it’s not obvious what the system is doing. Yes, sure, now that I’ve read other reviews I realize that a blue temperature means the system is cooling, but one shouldn’t NEED to read reviews to understand how it works.Oh, and I happen to be a software developer myself with a background in UI design, and a fundamental rule of designing a good GUI / HMI for widespread use is that you NEVER rely on color alone to provide information. Because there’s this thing called “color blindness” that affects a significant portion of the population and, well . . . see the problem there?

I have had my moments. I’ve gone from ready to pull it and my hair out to pure satisfaction. It’s been like raising a child. (A sick child sometimes.)#1 frustration: Lennox support does not have any idea about what is going on. The app has gone through a couple of updates. When doing so it has quit working completely. When eventually reaching Lennox support they had no idea as to what was happening. They are so clueless as to not even knowing they had such a product. I’ve never had any satisfaction from Lennox or their dealers. #1 solution: WAIT and you may wait a very long time. I’m talking months. It has always eventually worked out the issues. #2 frustration: Every update seems to have removed some features. In the beginning I recall I could adjust its temperature with the time of day. This feature no longer exists. I miss it. I’m building a new home so I have been researching other manufacturers Wi-Fi Thermostats. It appears that few owners are happy with their devices. Thinking back to business school I think I know what is going on. These little ad on features generate no revenue for the company. It’s a free-ish feature. It’s probably contracted out to a cheap foreign developer. You get what you get but it’s still evolving. Patience has no fans. As of this writing it’s working great!

I have to admit that until I read the response to one of Other reviews I was going to give the app a poor review. I couldn’t believe the system status was gone. Apparently it’s not... it’s there but not obvious. I’ll chaulk that off to poor communication... something we’re all quilty of from time to time. Anyway...I like the new format. It’s simple and unambiguous. What’s most impressive is the performance. Its tremendously better than before. That alone makes it ok for me. As for the system status bringing indicated by the color of the temperature... clever but not readily apparent. But, before we criticize this developer... Apple does this all the time with their products. After many years of using an iPhone I just found out that to undo a deletion in Notes you shake the phone! Who knew? Regardless, the color thing is not earth shattering.. give the developer a break

Update: After repeated requests to Lennox directly, still no response to getting a link back to the old app. Since my initial review another problem has arisen. I needed to reboot the wi-fi box. All other apps and devices reconnected immediately. This Lennox app DID NOT. It took almost a WEEK for Lennox to recognize and get the app going again. I am handicapped and rely on the app for temp control. With the oncoming of winter the Lennox lack of app support and monitoring is NOT acceptable and could be life threatening. The new app is BORING and TOTALLY USER UNFRIENDLY!!! DO NOT UPGRADE!!! NO animations (needed, needed, needed!!), NO beautiful weather forecasting (just extremely downsized, barely there and confusing line drawings). I WANT THE OLD APP BACK!! This is NOT an upgrade! It is a SEVERE DOWNGRADE! Where can I go get the previous version?? I HATE THIS UPGRADE! They took away what was a beautiful app and replaced it with TRASH! Again, DO NOT UPGRADE!! Reply to the email they give in the description so we can get our old app BACK!!
