This was a basic, but useful app. Now it shows a slash screen that may or may not go away after 5-10 sec. Then shows an ad for something, with countdown time on upper right. Then finally it works on iPhone 11 Pro. A useful app ruined.

Does what it should, display tiny screens from micro meter onto phone. Limited functionality.. does what the meter does. Today’s bugs, the languages screen washes out white on iphone 12 up to date. So if you happen to change language theres no way to restore w/o deleting and reinstalling app. Serial number displayed and usage counter displayed are both Chinese headers, please make those language of choice. Love the flip screen button!! Keep up the dev :-)

Installed app, set up TC66C to measure current from Anker charger to Anker power bank, then opened app. It found the TC66C quickly and shows the values (current, voltage, watts, amp-hrs well). Also provides easy export of logged data to Excel file and easily changes the screens displayed by the TC66C.Possible improvements:Change screens displayed by app to mimic those selected for the TC66C.Provide some guidance about the information shown by some of the app’s data fields.Allow resetting of logged data from the app.Overall a handy, functional app supporting the TC66C usb “multimeter.” I’m glad it’s available.

Waste of sending money on a product that doesn’t even work!!!!!
