### 2/5 — Didn’t work no more

*2025-06-21, version 1.7.18*

App doesn’t work no more & didn’t show a percent of battery no more

### 1/5 — Useless App

*2022-09-14, version 1.7.18*

It only connects to the battery’s about 10% of the time, I haven’t been able to check the battery’s status for a few weeks now.

### 1/5 — Seriously?

*2021-11-25, version 1.7.8*

You expect people to pay 300$+ for a battery but haven’t updated your app in over 3 years? I was about to buy one of your batteries but now, absolutely not. 😂 Incredible.

### 3/5 — Good app but needs improvement

*2021-07-06, version 1.7.8*

I bought the Cellink Neo I think about a month or two ago. I really appreciate the app since it tells me what the battery percentage is. But the app only works when on WiFi. When I’m on data, I go into the app click on my device but then the whole app closes down. Doesn’t do that on WiFi tho. I hope the developer fixes the issue for the app, since the device and the app are great products.

### 4/5 — Had to turn Cellink off and back on

*2021-05-05, version 1.7.8*

For the app to find my battery. The app worked flawlessly for years before I had to power cycle the Cellink. I literally just had to switch it off for a few seconds for the app to find my battery again.

### 1/5 — Garbage

*2021-04-19, version 1.7.8*

I don’t need a notification to tell me that I’ve walked away from my car, I can work that out for myself thanks very much. Switched off the quite unnecessary beeps and then deleted this useless app.

### 1/5 — Not working

*2021-01-07, version 1.7.8*

App has stopped working and won’t open anymore

### 1/5 — Deceased and no one at Cellink seems to care

*2020-12-21, version 1.7.8*

App stopped working. Cannot view any information about the battery as the app will not connect at all. 

Sent Cellink an email months ago which has gone ignored and the app has not been updated. 
Even the newer version “Cellink Neo+” works with the battery, so I have no idea how the battery is performing any longer.

### 1/5 — Works, but needs settings added

*2020-11-26, version 1.7.8*

Update: since Nov 2020 the app won’t even open after iOS 14. 

This app connects to my Cellink Neo 90% of the time. The other 10% it just doesn’t see the battery and I have to manually close the app and relaunch it.

Secondly, and others have mentioned it, when you walk away from your car and the app disconnects, it sends you a notification saying your phone has disconnected. This is going to happen every time you walk away from your car. There is no option to disable this message, and it is tedious to get inside the house at 2am only for my phone to BEEP and wake everyone up, because of this pointless message.

It would be useful if there was a setting to disable this message.

On the other hand, this message could be useful if it gave you some basic information about the battery. For example “Cellink Neo at 76%, approx runtime 36hrs”.

### 2/5 — Only useful to turn off beep setting

*2020-10-31, version 1.7.8*

The app only allowed me to connect to the battery once, after that it kept crashing. It was just long enough to disable the annoying "beep" when the 12V supply is turned on or off.
