I've been using this program from 7 to 10 years.... All of the sudden, out of the blue the app will not load or save files to anywhere on the phone or the SD card. I haven't change configuration in a long time but I tried today and it won't allow it so I don't know when this happened.... So this was a five-star best battery manager I've hand for over the last 10 years... And now if I can't save and load configurations it's kind of useless....

Thanks for your great support. This app monitors battery data and allows exporting it's history from app settings, it's not offering load/save files in the first place. Not sure what you are experiencign, but I just tested import/export and it works fine. If you contact me maybe I can help.

This morning when I turned on my phone I got a full screen ad slapped in my face. I navigated to the list of opened apps and was able to ascertain that the offending app was 3C Battery Monitor.. I have not interacted with this app for **months**, maybe even more than a year. I installed it when I ran into battery trouble on a previous phone. Did not need it on this phone, but it was automatically moved over. Apps randomly slapping full size ads in the face of their users is PLAIN UNACCEPTABLE.

I really like the app but noticed the pro version I purchased is no longer. Looks like you have to start off from scratch and purchase each component which I'm not happy with. Again it is a really good app but I feel since I already purchased the pro version a long time ago, now I have to buy each feature individually. Not happy with that.
