Does their app still stink or have they improved it by now?

Still bad from what I'm reading. E.g:
Moondrop May (IEM with USB C DSP cable)
Just got the Moondrop Chu2-DSP. It appears to be a Chu2 with a variant of the CDSP upgrade cable combo. I assume it will replace Moondrop JIU. Chu2-DSP requires an updated app (APK), available on Moondrop website, to work correctly. I downloaded the upgrade and, interestingly, the app gives a...

But it is balanced and they talk about a "new moondrop app" in the advertising with online tuning but i didn't really digged in.

The FreeDSP has differential output, just like the Echo-B.

Have you seen the size (depth ) of it ? Like having a building sticking out of your ear .Meteor is fairly recent and like a Variations 2.
Uh, I was thinking about the c-dsp who knows why, but I didn't know it anyway

Tru dat
I’m pretty sure FreeDSP uses the Synaptics, ex-Conexant, CX31988 (or CX31998 as referenced sometimes: I think they are the same).
It is the balanced (differential) version of the very common CX31993. They both have some integrated ARM Cortex MCU, no separate USB bridge needed, but I think Moondrop PEQ implementation is largely proprietary.
The app still sucks… but IMO, it’s definitely better with Chu-II or CDSP—same app, different chip.
Which brings me to this: I don’t know how much of the app”bad” is due to Moondrop SW team, or simply constraints & limitations of the chip itself. After all, I have yet to see PEQ implemented on another CX31988 (or CX31993?) by anybody else.
I started sniffing USB com’s between sources and these ‘smart’ DACs (strange addiction, isn’t it?
).I believe you mentioned a Beta to integrate these devices (starting with FiiO) directly into your Cringraph/Squig database—directly programming the device PEQ with no need for an intermediate file or app.
Moondrop, FiiO, TTGK appear to go toward EQ cloud-sharing of—curated or not—EQ profile for various HP/IEMs.
I can “smell” the potential… but I’m not sure this is the “right” direction… Any insights?
In the meantime, I pretty much stopped sniffing USB!
And I have resisted buying Echo-B.
Yes, I have see that in their apps and I can understand why they are doing that - it brings in a whole social sharing aspect - but you mostly have no idea other than the name of what a specific shared PEQ will do. Especially when applied to cables / dongles on their own. Though it might make more sense with a specific DSP enabled IEM e.g. Change the tonality of the Moondrop May to be similar to Moondrop Dusk with one click.
And yes I have a beta of some code to push and pull PEQ filters directly from attach USB devices - I decided to repackage it a little so it can be more like a plugin as there are many many variations of that original CrinGraph codebase on various website and maintained by lots of different people now. And given how often new Usb / PEQ devices are coming out I feel it will be easier for people who maintain their measurement database to maybe take a drop of this "code" every so often. I have contacted a few other manufacturers and some have shared some details of their protocols ( and some have promised they will soon) but given the number of Moondrop devices I am very interested in getting support working soon ( though I suspect I might have to just rely on usb-sniffing as they didn't respond to my email request ).
Well, that's why the call it meteor. Meteor is big
Now i'm worried if they'll name a new model Asteroid...

Wow, tower iems.
I'm waiting for the first one asking if they will be suited for using laying in bed
