The app provides valuable information on the batteries and works well with multiple batteries. However, the battery connection and name is not saved so you have to re-select the batteries every time you close and reopen the app. Furthermore, it is unable to filter out non-epoch devices so all the wireless devices in the area show up in the list making it even more inconvenient to find and select the right devices.This can get very annoying when you want to use the app frequently to check the status of your batteries. This should be a relatively easy programming fix to save the device address so hopefully this will be fixed soon.

Yesterday, the app had the worst Bluetooth connectivity interface in the history of mankind, in that you could never reconnect upon app minimization, the app would show Bluetooth devices having nothing to do with Epoch, including Bluetooth headphones, etc., and it would “favorite” your device, so you’d have to select it every time. But at least once you got connected it would pull all the pertinent data from the battery. Today, it has an all new look to it….and it doesn’t work at all. Battery shows 0%, no voltage, no data whatsoever. So amazingly, despite the Bluetooth interface before, it was actually better than it is now.I emailed customer support with my thoughts on the app a week ago, mostly as a test of their customer service department, and have not heard back. This is not good, and is very telling to me for what I can expect if I ever have a problem with the battery.

I bought this great battery however the app is horrible. It says be within 10 meters to connect but I have to be within 3 ft or the device can’t find the battery. Another problem is it automatically turn off after a minute so when your looking at different screen you have to go back and turn it on again. I wish I would have bought the cheaper battery and put an eviction shunt and saved money. Also can’t update because it wants a password that’s supposedly not required. Horribly disappointing

The previous app had its issues but at least it showed all the critical info that battery owners really need. The new update is so bad i’m not even sure where to begin. Who’s Great idea was it to remove and separate most of the important information and add some disconnected, irrelevent graphical interface that no one asked for. It’s so bad im actually a bit astonished that epoch could produce this garbage or let it pass onto their customers. all they had to do was fix and tweak the old app a little. Instead we got some colorful, flashy whatever you want to call it mostly useless garbage. was going to buy a couple more batteries from epoch, but now i’m starting to question the leadership over there and potentially the product.The app seems really disconnected from its users who understand what lithium batteries are and how to care for them and instead is trying to make some flashy gimmick to wow the ones that don’t. At the very least epoch should release the old app as a separate app so those of us who manage our batteries can have something useful to use and those that love pretty, flashing colors can have the new version.
