This APP warrants a ***** rating !

This APP is on the iPhone, iPad and iPro of every family member in the home. It has been perfectly flawless for the years it has been installed in each piece of equipment. I cannot think of any single reason for not having it in service. And NO, I am not being paid anything by anyone to endorse this program. I thing it is perfect !

Notifications Do Not Work

This App is the worst App I have ever installed on any platform dating back to the Palm III. The voice alerts’ level numbers don’t even match the visual numbers on the screen, often a difference of 10 to 20%. The alerts are setup at 5% intervals but seem to announce (incorrect values) at random times, every minute or so, including values not even within the user specified range. The configuration screen includes a warning that if you’re not connected to the internet you may miss or get delayed warnings! ¿What does the internet have to do with my local battery level?

This is the most useless App I have ever paid for or received for free. If I told you what I really thought I’d get censored so this is the watered down version.

Developer Response ,

The app should get notifications even if it's not in the foreground. Because (in contrast to the Android version) there is no continuous background service. Apple just doesn't allow that. What we have is a combination of local warnings and background notifications that update the app on a regular basis. This can explain some of the delays and why warnings (or chart updates) may not work offline.

There are better FREE apps in the market

Disappointed that there is no way to auto calibrate battery information in the app including how much battery capacity is left, maximum current battery capacity, amount of charge being consumed at the moment in mA, rate at which charge drops through a single charge and discharge cycle with normal use and when at a steady consumption rate to calculate actual battery percentage and time left (battery health). Also please explain how you calculated the times for the battery consumption in terms of mA. Please update your app with the following changes if possible.
