Very Useful Tool

Whenever a particular app shows itself to be exceptional, I am compelled to give it a positive review. I am aware of the difficulties that can arise when a developer submits an app to Apple for distribution on the App Store and I’m also aware of exactly how valuable a positive review by a consumer can be.
This app is easy to use, user friendly and very accurate if one follows the instructions provided. I had the opportunity to check test results with an outside charger testing tool and the accuracy of the results performed on the Amperes Lite app were surprisingly precise.
I also had the pleasure of dealing directly with the app’s customer support. My inquiries were met with prompt and courteous responses and I was impressed by the thorough nature of those responses. Customer support was very friendly but also professional and knowledgeable. 5 stars.

Very helpful!

I know some people would like to see this app display how much current the battery is receiving during the charging operation, but that is not possible at this time, as Apple doesn’t make that data available. So, given that limitation, I found this app to be highly useful in showing me the relative charging rates of various cables and power sources. I’ve found the app to be consistent in the results it reports, having tried the same cables multiple times using the same power source, then trying them with a different source. Nicely done....thanks!

Perfect App!

Thank You Andrew, this app is perfect for my needs. I have the new iPhone Xs Max with fast charge capability. I purchased several adapters, (usb-c & usb-a) & wireless in both formats. I’m testing various cables by different manufacturers. With your app I am able to test all combinations so I can use the accessories with the best results! Also the ability to label the tests helps me keep my results organized! Great app! Keep up the good work! Update:This was for the full app as far as labeling goes.

Thank you very much for the review! :) Cheers. Andrew
