Please fix. ### 2/5 — Unreliable *2025-11-04, version 4.0* I am connected to the WiFi with a strong signal and stand a foot away from the plug and keeps saying offline so annoying! When it’s online and working I really love it but it’s become very unreliable lately! ### 3/5 — Tighten up *2025-09-05, version 4.0* Your getting a 3 star and not a 5 because of how long this app has been out and there is still no option to add a widget be so fr tighten up ### 4/5 — App Suggestions *2025-04-09, version 4.0* I LOVE my smart plug minis. The app is very user friendly, and setup is super easy. I have two suggestions that would really elevate this app. Firstly, we really need a night mode! It would be really great if the app had a setting that would turn on a dark mode after sunset so when you turn lights off at night, you aren’t blinded by the white background. The other suggestion is to add widget compatibility. I have another app called LIFX for a smart bulb, and I am able to add a widget on my iPhone Lock Screen to turn that bulb off/on. This option for KMC Smart would be AMAZING! Altogether, good experience, but I think there’s some opportunities for even more greatness here. ### 4/5 — Excellent device *2024-06-23, version 3.0* DARK MODE PLEASE!!! My eyes hurt during the night time ### 4/5 — Work well, but…. *2024-03-03, version 3.0* I’m using four devices in two locations. They certainly function as on off switches via the app. There is a timer functionality/on off options via sunrise/sunset, however, it doesn’t seem there’s a way to say : go on at sunset and off at 10 pm. You can only set the on, and have to turn them off manually. I would absolutely give five stars if that were fixed . ### 3/5 — Needs Update *2024-02-20, version 3.0* This app is very lean on features and flow. For example, I tried to name the device and it couldn’t handle the number of characters. It doesn’t flow well when accessing your devices by room. I do use Alexa, but the names were captured incorrectly because of the character limitation…needs work! ### 3/5 — App freezes *2023-11-01, version 3.0* I have used this app for a long time and has been working great until a few weeks ago. When u go into the app it freezes and doesn’t work. I can’t click on anything. I have uninstalled and reinstalled but keeps doing it. Not sure what is going on but it has always worked until now. ### 4/5 — Plugs *2023-08-06, version 2.0* I’m disappointed that these do not work with Alexa voice control ### 5/5 — Handy Idea! *2022-03-16, version 2.0* These smart plugs have sure simplified our lives ! ### 5/5 — GREAT app!!! *2022-02-27, version 2.0* This app works great with all my WiFi plugs and lights in my house. Turn on, off and schedule from my phone anywhere. Keep up the great app and products. I am a absolute satisfied customer of yours for many years and many more. Thank you:) ## Most critical reviews (10 lowest-rated) ### 1/5 — App Night Mode *2026-05-22, version 4.0* Are you kidding? The blinding white screen at night is ridiculous. It’s 2026 FFS. ### 1/5 — Energy data page is too zoomed in *2025-06-12, version 4.0* I do wish though when looking at the energy statistics for the month, it would include the actual day below the amount used, as of now it’s very zoomed in and cuts off the numbers on the graph even at times. I have to sit there and count 1 by 1 to figure out which day was what. Hopefully they add the dates to the bottom of the usage lines in the future ### 1/5 — Pairing issues *2024-04-22, version 3.0* Cannot pair slim smart plug to more than one iPhone. App says that you can but every time I try to add a second phone, the app removes the device from the previously connected phone. ### 1/5 — does not connect with alexa *2024-03-15, version 3.0* This is a scam, they do not connect with Alexa in any way! If you want to connect it with Alexa, don't buy it ### 1/5 — Not working since update *2023-11-23, version 3.0* Plugs have become inactive and unable to sync to Alexa ### 1/5 — Not working anymore *2023-11-09, version 3.0* Worked fine until I updated it. Now all my devices are there but when I try to switch them on/off every device says it’s “offline” and it takes a long time for it to randomly go back “online” so I can work the switch. My WiFi and router work fine. This app is now so annoying to use I want to throw all the stupid “smart” plugs away. ### 1/5 — Be carful don’t install this App *2023-03-15* Hello I know this company Chinese , this company can upload everything from your phone , there’s no privacy with this stupid company Chinese ### 1/5 — Unable to pair device *2023-02-17, version 2.0* Unable to pair device no matter what I do - I tried unplugging the device for 30 seconds, resetting the router, turning my phone off/on. ### 1/5 — Loses all devices *2021-06-27, version 1.1.8* Constant trouble. ### 1/5 — UPDATE *2021-05-31, version 1.1.8* New update won’t let me reschedule what I already had set. I’m incapable of rewriting or see whati have set. Also, I’m incapable of adding new devices because of the way they did it. ## Most praised reviews (10 highest-rated) ### 5/5 — So far so awesome *2024-07-19, version 3.0* Very cool app which allows you to control and customize the way you can use their products. Has different features such as turning on outlet switch on or off based on the weather, or other outlets state. There’s more features that allows for more customization with relative ease. Haven’t tried them all yet. ### 5/5 — It works! *2023-09-21, version 2.0* I bought a 4 pack of these pass thru Wifi adapters. Easy setup. Couldn’t be happier! ### 5/5 — Easy to use and setup *2023-08-09, version 2.0* The remote power controllers are easy to setup and manage with the app. Makes it super easy to control power devices in my home. ### 5/5 — Muy fácil *2023-07-21, version 2.0* Muyyy sencillo de usar, la instalación es muy sencilla y la Interface amigable ### 5/5 — Excelente *2023-05-12, version 2.0* Excelente calidad y un precio muy económico ### 5/5 — I have several *2023-05-01, version 2.0* I have grow lights on timers. That works absolutely fabulous. I can turn the lights on before I go in the bedroom just by talking to them I can turn the lights off. If I forget them downstairs I can make the lights turn different colors if I have the right lightbulbs, it’s wonderful ### 5/5 — Very good *2023-04-18, version 2.0* Works great!!5 stars ### 5/5 — Love KMC smart plugs. *2023-01-09, version 2.0* These KMC Smart switches work better than any switch I have ever used. Can be sent to default on, or default off. ### 5/5 — Good product *2022-12-12, version 2.0* Ordered multi smart outlets a couple of years ago and was impressed with the features and easy programming. Since then I ordered single smart outlets and absolutely love them. Would recommend these ### 5/5 — Muy buen producto *2022-04-11, version 2.0* Súper recomendado!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
