### 2/5 — Stopped working

*2025-08-18, version 2.4.5*

Was good until about 4 Months ago April 2025

### 1/5 — Missing In Action

*2025-06-13, version 2.4.5*

Sensor continually drops out of Bluetooth connection. Frustrating to say the least.

### 1/5 — Poor connection

*2025-04-27, version 2.4.5*

The blue tooth connection is terrible the app is so poorly designed it’s comical and ctek do nothing about it

### 2/5 — Poor connection

*2025-04-20, version 2.4.5*

The blue tooth connection is terrible

### 2/5 — Batter voltage scale needs improvement

*2024-12-30, version 2.4.5*

The battery voltage scale is currently zero to twenty five volts.

This makes it very difficult to examine the small changes in voltage which provide the key information on the status of a lead acid battery.
A better scale would be something like eleven to fifteen volts.

Yes, the state of charge graph is very useful, but if there is a voltage graph it should be useful too.
CTEK products are excellent. I’ve owned a few.
Please update this app and bring it up to the CTEK level of excellence.

UPDATE:  Years after making this post, still no update or improvement of this app. It could be so much more. I have purchased other CTEK products recently but am VERY DISAPPOINTED in CTEK’s complete lack of interest in evolving this product to at least provide usable voltage information.

### 1/5 — Don’t use this

*2024-10-30, version 2.4.5*

CTEK Support says that it updates this app to fix critical bugs.  That simply is not true.  The current app is simply not fit for purpose, and CTEK should be very ashamed of not addressing the problems.  I feel completely robbed having purchased this product.  Never again. People take note and do not buy CTEK.

### 2/5 — Will not clear date.

*2024-08-10, version 2.4.5*

Cannot clear past data even though it asks to confirm . Show landscape mode and data still showing.  The only way to clear is remove sensor and start again
Using iPhone 15

### 1/5 — So much wasted potential (updated 2024)

*2024-07-02, version 2.4.5*

I like the app in general. But it could be so much better. Bug: you still get notifications despite having disabled them in settings ( no status update for 7 days) which is a PITA when your other car is 1600 miles away ....

Update 2024 - tried installing and binding to a new iPhone 15 Pro Max. App just dies after entering the “code” with no warning.

### 1/5 — Got worse after update on Apr 2024

*2024-04-27, version 2.4.5*

After the update, the app gets stuck for minutes. Got slower, already a slow app. I appreciate that they are still supporting but it seems they don’t do enough regression tests before release.

### 1/5 — Ok for a week

*2024-01-13, version 2.4.3*

So basic. Pretty poor though. My actual sender unit no longer connects to my phone via the app. The sticker with the number to connect is long gone. Its a very nice idea to be able to monitor your power usage but it shouldn't be this hard. Not worth the trouble.
