Massive well done to
@Tronsmart Official who delivered on their promise of Apollo Bold app support by the end of September!
I've been working with them to iron out a few creases in the Android version, in a week they have made GIANT strides, fixing or remedying everything I mentioned and have released it now on IOS and Android. The beta allowed you to upgrade from fw 1.0 to 1.4.0 - now they are on 1.2.3, so these guys must be working day and night!
The firmware must be updated one bud at a time. Take one out of the case, update, then swap them over and repeat.
This is their first iteration so the controls are fairly basic at this stage. The main screen gives you battery indicators, and toggle buttons for ANC and ambient. The three dots in the corner take you to the next screenshot, where you can update the firmware.
First thing to do is update the firmware. I was testing 1.04 so to move to 1.2.5 shows they've been pulling out all the stops - the new version supports different EQ's, enables customised touch control, and distinguishes between the left and right bud when used in single mode:

Updating the firmware is done as per the clear instructions:
1. Take Left earbud out of case which should remain open
2. Initiate firmware download and install. Do not navigate away from the app and ensure the case and buds have sufficient charge
3. Once complete, restore the updated bud to its place in the case and remove the other
4. Repeats step 2
5. You have updated your firmware!

The Equaliser is a little rudimentary but it does a job. I know they wanted to integrate a spotify-style dynamic EQ - unfortunately it was outside the scope of what was possible within the timescales.
The default profile seems to notch the bass off a little more.
The classical overcompresses the mids
Jazz is nice, probably my preferred EQ after the default
Pop rolls the top end off and is ideal for dance music where it can be uncomfortable on highhats
Rock is pretty awful -avoid!
The new default handles the bass nicely now, and doesn't compress the life out of the mids, so those of you complaining of subbass rumbles should try this EQ first.
Finally, the controller. I haven't tried changing the settings as I like the existing ones, but here they are:
There is a spelling mistake on ambient, but we can let them off
Finally, to answer some questions:
Q1 - Is Aptx-HD supported?
A1 - No, not yet. Tronsmart are working with Qualcomm to try and get there - the issue lies with Qualcomm, not Tronsmart
Q2 - Is the mic quality better?
A2 - No, it sounds identical, perhaps a little more distant and slightly better at cancelling out background noise, but this could be the placebo affect!
Q3 - Any other comments?
A3 - Connectivity is definitely more stable, the app is intuitive and easy to use. As we have seen with Edifier, first releases are quickly followed with updates, so hold fire on flaming them for the apt-xhd situation and congratulate them on keeping their promises!
