If already logged in and have no Internet, you will get a network access error but can see battery stats. However if you get logged out for one of many reasons you will be presented with login screen and need Internet to get to next screen. This needs to be addressed. A login is fine for firmware updates, but should not be required for Bluetooth connected battery info. ### 1/5 — Requires an account not good for offline *2025-03-16* This app requires an account, which would not allow operation offline such as in a remote place one may use LiFePo4 batteries to live. I also disagree with the obvious data collection tactic ### 3/5 — Disappointed *2024-12-07* When choosing Lifepo4 batteries I also considered Bluetooth functionality and how well the App operates. While I could not find a review of the Timeusb app, I did consider the App Privacy summary which claims “data not collected”. I seriously doubt that statement as the app not only requires an account to be registered, but also requires Internet access and location services enabled to operate the app even after initial account registration This is a huge downside to me by not only being an invasion of privacy but I now cannot obtain important battery information via Bluetooth when off grid and not having Internet access. I’ve just tested this numerous times and you must have both Internet availability and location services enabled to view any information via Bluetooth To the app developer, please change this requirement. I now have to purchase a separate Bluetooth shot to get battery information as I often in areas that don’t have Internet access Besides this huge downside, the app itself is very bland does not provide information about the individual cells just the very basic information ## Frequently asked questions about Timeusb ### What devices does Timeusb support?
