Solid app for the price

It does have a handful options for the user to configure for their own needs. I don’t think it’s super accurate but seems to be able to give you a reasonable idea.

I have one confusion though: what is the difference between “Amperes” and “Amperes 3”? I purchased two apps already but it seems the new one does the same thing as this one but I cannot find any upgrade options…

Developer Response ,

Thank you for your review. Amperes is actually Amperes 4. And Amperes 3 is an older version, that we had to release since after the release of Amperes 4, many users were not happy with a new UI. As such, we returned the old UI in Amperes 3.
Best regards,

Great support from developer

Edit: all issues were addressed.
Please add a conformation step before clearing results data. Very easy to accidentally delete all one's measurements otherwise. Also being able to edit the test configuration info after a test is run would be very helpful. Also where test results are displayed (at least on an iPhone X) the fields with the Name and Charge get cut off with no way to later see what was typed originally. Finally, there should be a note to users that the charging rate, or score, varies greatly with how full the battery is. Perhaps recommending all tests be done under 50% would be better than the 90% required now.

Developer Response ,

Thank you for letting me know that! Editing of the test configuration will be added in the next version. As well, confirmation before clearing the results will be added. I am planning to add more detailed help instructions to the app, where I will cover the charge % as well. Regarding the Name and Charge cut off issue, could you please send me a screenshot to Thank you!

Great Tool!

What an outstanding app. I have multiple cables and charging devices and this let me determine which configurations were best and just as importantly, which were worst at charging my iPad Pro.

Since I travel a lot I was pleasantly surprised to determine a thin cable charged just as quickly as a thick, bulky cable. On the other hand, I was disappointed to find out my Qualcomm 3.0 Quick Charger didn’t charge as fast as my NewerTech NuPower 60W adapter (fortunately the NuPower has 2 outputs so I can charge both my MacBook and iPad at the same time)
