Necessary for Cefaly - only reason for 3 stars.
This app by itself merits a 1-star review - it’s terrible. It allows very basic control of the Cefaly device but crashes, has an awful UI, and is generally a pain to use. Basic functionality (like ramping down intensity if you let it get too high) is missing.
That said, if you use a Cefaly, this app is helpful despite its many flaws. I find the Cefaly itself very helpful for migraines, so I’m stuck with the app.

Great device, terrible app
Update 5/5/2026: still love the device. App still sucks.
I love the Cefaly device, but the app is essentially useless, which means spending the extra for the connected device was pointless unless they fix the app.
I have to enter the device pin every time I use it, the app frequently restarts the session, then never ends up actually logging anything.
I will just use the device manually for now, but I really hope they fix the app soon.

So frustrating
This has to be the worst medical app available. If gives me a headache trying to use it. Please fix the app so I don’t have to input a pin to use the device. Also please stop asking me about my day and focus on getting the device to stay connected and work. How about a Home Screen that says acute and prevent so I can pick one and the device just works. Maybe another button that takes you to a screen for people that want to give you their life story. This shouldn’t be so complicated.

If I could give an app 0 stars, I would!!
This app simply does not work. At best, it is difficult to navigate. At worst, it simply doesn’t work and makes the user experience of doing a Cefaly treatment WORSE. It really bothers me that when I go into the actually treatment graph screen that the brightness dims COMPLETELY and will not allow you to adjust. I have to strain my eyes to try to see the intensity of my treatment. Save yourself the trouble and just learn how to use the buttons on your Cefaly well. That, and a timer will work just fine. Love my Cefaly otherwise, but man is this app terrible.

Horrible
I really wanted this to work but the app is completely broken on iOS AND Android. I don’t know if it’s the device or the apps. Someone else said the app used to work so I’m hopeful it will be fixed. Most likely returning this $700 device though. What a shame.
App doesn’t work
Constantly closing mid session, doesn’t save my information. 0/5 stars. Thought it needed an update but it literally just doesn’t work. Thank god you can use the device without the app
Why can’t they get this app fixed?
I have used a Cefaly for years and I love the devices but the app is terrible. The newest version finally lets me use my phone while using the device without dropping Bluetooth most of the time. I really hate the new light dimming feature. It does not allow me turn it off. Also, why make me pair every time and go through welcome tutorial? Truly the worst app! Wish they would get some new developers. I would pay for a really good app, but not this junk.

Expensive device for it not to work
Why is this app such trash? Expensive device, yet the app doesn’t work at all. Fix yourself.
Device Can’t Connect
The app functionality is again impeding my use of the device. The app cannot find the device, despite restarting the app many times and charging the device to ensure battery isn’t the issue (it was last at 70% so it shouldn’t be). Very frustrating! Second time the app has broken in my 2-3 months of use.

Disappointing
The machine works, but the app really sucks. Anything you try to track doesn’t save, the controls for the machine are slow and sometimes don’t respond at all. The app is basically useless which is really disappointing for the price paid for the product.
Horrible app
Won’t connect. Won’t sign me in. Tells me I signed in with Google last time, which I didn’t, and still won’t sign me in. Then tells me my acct is inactive and to email for support. I did that. All they tell me is to delete the app and download it 24 hrs later. Thanks. Doesn’t work. I magically signed on once. Can’t get the device to work without the app.

Device works but cece app does not.
Device works wonderfully thank you. However the app does not. I’m on a iPhone. Once installed I can work some derides but Bluetooth drops a lot. Next session a screen pops up with nothing on it and it does not go to features. Just a blue screen.
Cece App pairing
I spent over 30 minutes trying to pair the device to the app to the point that the app stop discovering the device completely. The upside is I didn’t pay for it but doesn’t fix the fact that the app isn’t great. 🫡
Bugs
Passwords never seem to work more than one sign in. Resetting the password is difficult. When you do manage to get signed in connecting to the Cefaly device seems to be hit or miss. Unsure how they made this app so bad but they figured out a way.
Terrible bring back old app
Terrible. Does no one at this company project manage anything? Doesn't work at all, and once I downloaded and tried this one the old app no longer shows intensity, or functions.
Renders device useless as can't tell what level it's on or how long is left. Furious with this company's service

This app just got worse with the new update.
Awful Application
This is supposed to help with my migraines instead this app is causing one!
Awful!
The CC app is awful. It doesn’t actually control the machine the way it claims to, and half the features don’t even respond. The app doesn’t follow basic phone settings — the screen won’t darken or dim correctly, even when the iPhone settings are adjusted. It also fails to track usage accurately, which makes the entire point of the app useless. This is ridiculous for a product in 2026. It needs a serious overhaul and real functionality, not empty buttons and broken settings.

Bad app design
Listen, I like this product, but this is just as bad as the original app. It constantly disconnects, tells me that my battery is low when it isn’t and informs me multiple times throughout my treatment that my treatment has started. I’ll open the app. It’ll tell me that my device is connected, it will not in fact be connected, and I will have to re-pair it every single time I use the app. It also doesn’t consistently log my treatments because the app will just crash.

Not user friendly
I purchased a Cefaly on my docs recommendation. Too some to tell whether the treatment will work for me but the app is terrible. It doesn’t kick me off as others have said but some of the features seem to be there for looks and nothing else. One example is the stabilize button. I get no reaction and so have to keep starting and stopping the acute treatment as I can’t take full power yet. Hurts like hell. I have enough pain in my life! I’d really like to give this a try but the app needs an overhaul. If it’s not fixed I may just send it back.
