Has Potential But Has A Long Ways To Go

First, I wanted an app that gave great details for how well my charger and cables were working. Something that would help me analyze my equipment to make sure I’m charging as fast as possible.
So far everything has failed me but this one is the best.
This App gives the most detail in a professional display.
Now for where I’d like to see improvements:
I would like to see Voltage, Amp, and Watts with the available views of Current Time (updated each second), Minute average, charts with 1 minute, 3, 5, 10, 30, hour displays.
I’d also like to see the phone temperature. Ultimately the temperature of the battery. I’m not sure if the IPhones have the abilities.
Lastly, I feel that if you choose your language, then other languages shouldn’t be displayed. For example, I chose English and many options of animation were in Chinese.
This isn’t a big deal but as it gets perfected I feel like it’s needed.
If the creator can accomplish this then I would be willing to pay for 2 cokes.

Wow! Best in Class.

This app not only has loads of great animations and art that you will love, but it gives you extremely detailed battery and charging information! I did not even know it was possible to do all this! While I was a bit worried I would understand how to use it, especially when some content still has Chinese labels, they did an outstanding job of onboarding in English and showing you step by step what to do. Love the art, love the UI/UX, and love the professional tech which often isn’t found with excellent art. Great job developers and artists!!!

My only concern is security. I notice that basically the app itself is running the animations, and the phone is therefore NOT locked. So, anyone can walk up to the charging phone and open it. I need the phone locked when I’m charging. Second, I notice that when I lock the phone and then charge from the Lock Screen, it of course fails if FaceID fails to unlock the phone, again demonstrating that the phone is unlocked during charging.

This might be a good app, but….

….I can find no information anywhere on how to use it. There are many abbreviations next to a lot of numbers and some numbers without even an abbreviation, but no explanation on what any of them mean. Much of this is probably of no importance to me, however, there is no way to learn what information is and isn’t important to a normal user. This app was recommended as a way to find what wattage that wall chargers are putting out to iPad/iPhone. I did find out how to do that, I think, but I question the accuracy. I recently bought half a dozen chargers that were advertised as being high speed, 20 watts and high speed, 30 watts, as well as different makes of high speed lightening cables. When I use the app to test any of them, I get various wattages from 2.5 to 12.5. What am I missing or doing wrong? I’d really like to buy the version of the app that costs $1.99, but I hate to waste the two bucks on something I can’t understand or use. I’d welcome comments to help me solve this dilemma.
