Impossible to use . Absolute garbage . Going back to Fluke !!!!!!! ### 1/5 — Won’t connect *2021-08-13, version 1.1.1* I never could get it to connect to my meter. I got a msg turn phone Bluetooth on. I would do that then get a msg turn on meter Bluetooth. I’d do that and the msg would stay the same with no connection. I tried contacting Southwire several different ways but got no response so I had to return the meter. ### 4/5 — A great start *2019-01-04, version 1.1.1* It works as advertised, but it doesn't seem to support multitasking on the iPad. Also, the screen doesn't rotate. ### 5/5 — backyard mechanic *2016-12-08, version 1.1.1* What a great idea when using your MM. Loaded this app to my Mini2 and it looks great and works....Screen not 100% though. Meter is the 16040T ## Frequently asked questions about MApp™ ### What devices does MApp™ support?
