Why does any of this matter? Because (1) the 121GW has BlueTooth for some good reason, right? And (2) it's a bother to remove the blue bumper and unscrew the back case each and every time you want to access data logged to the SD card. I'm very glad that SD card exists, but disassembly is required to use it. No disassembly is required to use BlueTooth and a smartphone app, however! Hence my posts on that topic.
Many products have app issues over their lifetime, it is a fact of life now. Best to just move on. The 121GW actually has it pretty good, with the official Android and Windows app still available and working, and recently someone put together some code to data log via Linux:

It should be trivial to pick up a basic Android tablet or an old PC for Windows/Linux.
...I think it's safe to say the only users who can honestly avoid shaming these days is Linux users...
OK, sure, I can tell you that neither the Windows nor Android apps appear to allow you to "freeze" the "waveform". Also, I don't think I would call it a waveform, just a graph/plot. It only updates about once per second and is cumulative. It also continues to graph even when you press Hold (the last value is used for subsequent data points).
The graph in the app can't be stopped, you can only reset it. Although any time the mode/selector dial is changed such that the units change, the graph is reset.
...For now, after reading your feedback on the official app, it seems Meteor has an edge over the official app.
BTW, someone just told me the iOS code I uploaded the other day is the KaneTest one instead of the official 121GW app
I'll have to check and correct this.

I took a quick look at the GitLab hosted 121GW App source code linked earlier, and it is a Visual Studio Xamarin/UWP app with targets for Windows, Android, and iOS.
I am not sure if the iOS support in there is complete, but loading it in VS2022 gave too many errors for me to deal with right now. Maybe someone with a bit more experience can try before I get another chance.
I use VS2022 to do some cross platform (Android & Windows) dev, but not targetting iPhone. I do have a Mac Studio where I maintain some older Objective C iPhone apps, but I'm far from an expert.
This is the latest and last official EEVblog 121GW cross-platform Visual Studio Xamarin/UWP app for Android, Windows, and Apple iOS targets.
i just had received my 121 GW Multimeter when I stumbled over the newest commit in the gitlab for the 121GW's Multiplatform App:
User Dave added to the Readme File:QuoteThis is the latest and last official EEVblog 121GW cross-platform Visual Studio Xamarin/UWP app for Android, Windows, and Apple iOS targets.
So what does that mean? Is the 121GW phasing out? Or is it just the App development, that is discontinued? Is there any official statement?
Hi all,
Regarding the firmware update procedure for the 121GW.
I have read the words in the manual but am still unsure of the exact procedure.
So, do I need an additional SD card to the one installed in the meter to load the new firmware? What capacity SD card? There is no mention of this in the manual.
My laptop does not have an MSD card slot, so how do I install the file on the card?
I realise these questions may induce a groan from the seasoned tech vets on here but I am just not very familiar with this stuff
except for the thickness, i absolutely love the size of this meter.

The original design was thinner and used AAA batteries. But for better battery life we decided on a thicker AA design.
but i do have a chromebook and an android tablet and i see there are at least two apps which support the meter, so i'll try them out for times i need a bigger display.
...when i started meteor for the first time i was supremely annoyed that it just started logging automatically and it literally took me 20 minutes to go through every menu item and to realize that to keep it from doing that i had to set the sample size to zero.

Just to let everyone know, the reason for all this discussion is because I am doing prep work for a YouTube video review of the 121GW. It was not given to me. I purchased it new at the end of January this year, direct from the EEVBlog store.
I just made my 121GW review video public here...
