🤔 ??? Cable Charging Only

Ok was checking another app out and came across this one
Well I don’t use a cable for charging cause wireless charging is so much better
Anyway thought it might be nice to see how the wireless charger was rating so downloaded the app
Got the screen with [ TEST ] and pressed test
Nothing so picked up my XR and then set it back on the charger with the app on XR showed charging yet the app again did nothing when I pressed Test
So does me no good since it doesn’t work with wireless chargers
So just to be Neutral I gave it a 3 ⭐️
Maybe it can be upgraded to test all charging ?
For now the app will be in 📂13 😆

Great idea

But it does not work on my iPad 5 or iPhone 8 Plus. The “test” never ends. Waited 20 minutes.
Problem was that I had my auto-lock set for 5 minutes and it needs to be set to never.
Another point is that to run a test you must run it to full charge.

Hi, Da Lightnin. I can't reproduce the issue. Could you let me know more detail? Does the watt show up? Or only show the time?
