Battery Sense

Both the App and Certa 12v Battery Analyser with Bluetooth work extremely well together. Would love to see some updates to better suit different battery types and the ability to delete individual trip data.

You can see the voltages nicely. However, there are two major downsides. Every time I open the app, it tried to force me to allow the app access to my location. I have to deny it every time. This is quite annoying. When you are trying to monitor the battery voltage, you want to look at the past data. Unfortunately you cannot get a better resolution than a full day. To really understand battery charging etc, you would need to be able to zoom in. This is not possible though. If both of these issues were resolved, if give 5 stars.

The app itself is great but the time on the large graft is always off by an hour forward. I have reached out to them via app about this and how to fix but so far no response. Hopefully they will see this and respond.

Remove the nag screen that requires you to turn location services to “always on“. Those of us just looking to open the app and intermittently check voltage – we don’t need the app constantly trying to connect through location services and draining our phones battery. It’s poor app design.

It works but really wanted to know temperature as it is important to battery health.

App graft not working as should on ios 16.1.1. Used to work fine with older iOS versions.

Bluetooth works while next to LNEX device. Security pin change works. Voltage page is clear. Flower shape design for main voltage display has different colors depending on voltage but nothing in manual/online about it. Short graph is clear but not very granular. Voltage detail page shows data for one day or custom but it has hidden data gaps, more in a moment. Latest data is plotted 1 hour later than actual. Selecting custom gives crowded/overlapping menu on smallest iPhone. Downloaded data reveals 5-6 large data gaps per day ranging from 20 to 55 minutes each! The detail voltage graph display doesn’t indicate any gaps, so smoothing overly compensated and down right deceiving. The cranking page is clear but the graph granularity is lacking especially when comparing between different starts. The charging page is clear. The trip page is clear but shows trips times 1 hour later than actual. Trips are missing due to gaps in data mentioned above, notwithstanding that the developers list numerous other reasons for inaccuracies. Overall 1 star but could be better if app is fixed. In contact with support … will update if any changes.

Very buggy when trying to install on multiple devices. Asked for suggestions from developer, but No Answer. This app needs work.
