Like what the hell? I have an iPhone 12 and Chemion worked fine till recently, yet on my partners S24 there was no complications. Is it my phone?? ### 2/5 — App Won’t Work *2023-11-11, version 3.0.1* Tired Restarting The App A Bunch Of Times, Even Deleted The App And Installed It Again, Nothing.. FIX THIS ISSUE!! ### 3/5 — It’s nice ( but ) can’t login to Facebook accnt *2023-03-31, version 2.0.10* Getting this Erro : App not Active, this app not currently accessible and the app developer is aware of this issue , you will be able to login in when the app is reactivated….. ### 2/5 — Failure to connect *2023-02-10, version 2.0.10* I’ve had the glasses for about a year now. They worked well and are in relatively good/new condition as they were only used once. Recently I’ve tried to use them again and they won’t be detected by the app. I’ve followed advise I’ve found on trying to fix the issue such as holding the button for 10 seconds multiple times. However the glasses still are unable to be detected by the app ### 3/5 — Glasses are great *2023-01-16, version 2.0.10* The glasses are great and few good on your head. The only problem I have is with the app. You use to be able to move around your custom sets but it seems you can longer choose where they go. It would be a 5 star if it ever gets added back. Other than that there is no issue with the glasses or the app. ### 3/5 — Accuracy *2022-05-27, version 2.0.10* I’m not sure why, but the app version I have doesn’t match what is shown on the uTube instructions I can’t get mine to load text that I’ve created! ### 4/5 — Bluetooth connection *2022-01-13, version 2.0.10* I got the glasses back on Christmas and it was working well but just today I tried to use em it won’t connect like it won’t find it and my Bluetooth and location is on the his apps needs an new update like I admire it jus need to fix connection feature ### 3/5 — Great but one thing needs fixing *2021-12-21, version 2.0.10* It works great with my glasses, but is it possible to turn up the max speed the glasses animations can go? It only goes up to 4 fps, and there are other animations that are way faster on the app itself. ### 2/5 — App won’t start! *2021-11-01, version 2.0.9* I just opened this up again for Halloween, I’m just stick in the loading screen ### 4/5 — Please Update your app *2021-10-31, version 2.0.9* It’s Halloween and I’m trying to open the app to use the glasses but the app is not working, please get the app working and functioning… ### 1/5 — waste *2021-10-31, version 2.0.9* app will not go past the starter screen. I followed the directions to the core and tried to delete and reinstall. Really wanted to have them for a costume this year. ### 3/5 — app not loading *2021-10-31, version 2.0.9* i used to love them but the app won’t load please fix ### 1/5 — Doesn't work after update *2021-10-31, version 2.0.9* Updated the app i had the old icon before, now my app doesn't work, it just get stuck on first screen ### 1/5 — Confusing move: *2021-10-31, version 2.0.9* I have been using the Chemion app for roughly 2 years now. For some reason the new update won’t get past the Home Screen. What a load of garbage because now I can’t use either of my glasses. What confuses me is that the last app worked perfectly. Zero problems or complaints. Then after a few months I got a new phone which requires the update. Now none of the products I have work to my phone. Garbage move Chemion. You just lost a customer for future products. ### 1/5 — App not opening *2021-10-31, version 2.0.9* Horrible piece of junk ### 1/5 — Fix the app !!! *2021-10-31, version 2.0.9* About a week ago, I checked the chemion app to see that it had updated, I updated it and when I enter into the app it just stays at the “Chemion turn your lights on” screen and nothing happens! Please fix your app chemion ! ### 1/5 — Fix the explorer in the app. *2021-10-30, version 2.0.9* The glasses do work and the designer works and all but the explorer has been buggy since I got these glasses over two years ago. Please fix the app already ### 1/5 — Update your app! *2021-10-30, version 2.0.9* Seriously? 5 months since y’all last updated it? I just got my glasses and was exited to try them and the app won’t even load up! I have an iPhone 13 and it’s not working on this phone. Don’t waste your money on these glasses, not worth the money for cheap quality in a app and the glasses. Fix your app before releasing something that’s $70 and that depends on it. ### 1/5 — App doesn't work *2021-10-30, version 2.0.9* I used this app once to test the glasses, and since then it refuses to open. It freezes on the "Chemion: Turn your light on" screen and does nothing. I've deleted/reinstalled, restarted my phone, tried disabling and reenabling my internet connections, everything. 1 star. ## Most critical reviews (10 lowest-rated) ### 1/5 — Quite annoyed you can’t use the search anymore *2023-12-10, version 3.0.1* This app worked well for a quite awhile but now as of recent you can’t even search for stuff anymore which was one of the best features what a let down, fix your app :/ ### 1/5 — Garbage *2023-11-09, version 3.0.1* This company is garbage. This app worked great for their old glasses. Then they made the app stop working so that people would switch to color Chemion. And conveniently color Chemion doesn’t support older glasses so they’re basically trying to pressure you into buying yet another overpriced piece of garbage glasses ### 1/5 — App doesn’t even work *2023-10-11, version 3.0.0* won’t even go past start screen ### 1/5 — Works only with Facebook *2023-02-24, version 2.0.10* You have to go threw your Facebook app to make them work and that doesn't work either what a joke & waste of money ### 1/5 — UPDATE YOUR APP *2023-02-02, version 2.0.10* App’s Facebook login is still broken, And now the app freezes on the start screen. ### 1/5 — Why *2022-07-16, version 2.0.10* Why chemion hat not connect to chemion app? ### 1/5 — Why Facebook? *2022-07-10, version 2.0.10* I was very excited to use these glasses until I couldn’t really do anything without having to “log in to Facebook.” I haven’t had a Facebook in over a decade and I’m not about to make one just to use these glasses. Super disappointed. ### 1/5 — NOTHING CONNECTS *2022-02-23, version 2.0.10* i turned off private mode, i turned on bluetooth, wifi, EVERYTHING. NOTHING WORKS. DO NOT BUY. ### 1/5 — It doesn’t bot up *2021-11-01, version 2.0.9* When I open up the app it doesn’t show the UI, it’s just stuck on the loading screen. ### 1/5 — Fix your app *2021-11-01, version 2.0.9* This app is not letting me get on at all it’s stuck on chemion turn on your light for the last 10 minutes ## Most praised reviews (10 highest-rated) ### 5/5 — 😏 *2024-09-23, version 3.0.1* Love them!!
