In defence of [Apple culling older apps incompatible with new iOS releases], the overhead maintaining multiple O/S compatibility in an App is not insignificant - and is often impossible with new features only available with newer operating systems.
Be that as it may, the fact remains that the smartphone APP is the killer "Logging" feature of the 121GW insofar as the app shows you a
graphical waveform representation without requiring you to unscrew and open the meter to extract the SD card which in turn must be put into a computer for the purpose of seeing a TEXT-only view of logged data. Want a visual representation of that text you extracted from the SD card? You must make time to graph it yourself! And after all that time-consuming work, you must put the SD card back in. Want more data? Wash and repeat! Ack! Glad the SD card is there, but man the app is so much better!
Most people who buy the 121GW, myself included, do so BECAUSE it has
data logging. If you don't need that one key feature, the
BM786 is perhaps the best pick. And when you want data logging, you want something fast, convenient, and if possible, graphical. The 121GW offers that by way of the smartphone app.
And so, I do hope that whatever happens now will bring us a better iOS app. Meteor isn't all that bad, but not being able to FREEZE the waveform on my iPhone's screen (without dimming) is a critically important feature that I am totally shocked and amazed that the developer of Meteor didn't consider. It would be great if that developer could read our discussion here, as that may inspire him to improve his app, thereby making my call for the official app to be reinstated to the iOS App Store moot.
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 had hoped to get the
Fuse pack too, but frustratingly, it was out of stock. In fact, I checked just now to find it still out of stock! Even the 121GW meter itself is often out of stock, so I snapped it up when I could. Had I waited for the Fuse pack to get back in stock, my worry was the meter would then go out of stock. Indeed, had I waited, I still would be waiting AND without a meter too.
By the way, selling the 121GW on Amazon (not simply on the EEVBlog store only) might be a way to give it free advertising and more exposure. It says "
Currently Unavailable" now on Amazon, despite the fact the
BM786 is available there.
