Hello. The app release is very good, should run on most phones with armv8.
Get it on F-droid:
https://f-droid.org/en/packages/org.bitbucket.watashi564.combapp/As mentioned above, there are number of known issues (mainly manifesting on newer phones).
Important:
Future development of haircomb coreI want to integrate accelerators more into haircomb core. I hope to have the current accelerator hash
the user is synced to shown on the main page.
A separate html page will be published that shows the current accelerator hash from the blockchair api. Said page can be hosted on public server etc.
I want to make haircomb core to work on phones with less RAM. Towards that end, we'll try integrating cuckoo filter.
Anyone wants to change something in haircomb core?? Speak up!
Future development of related projectsThere are multiple ideas floating around about what to do next, like the accelerator network, about doing the turbine, eternal file etc.
We want to make sure these ideas are well understood but in the end it matters what ecosystem a coin provides, even without quantum computers etc.
So, let's try our best

Focusing on the accelerator stuff early makes sense to me. Turbine stuff is neat and all, but it only really becomes relevant once it becomes too expensive to normally transaction COMB on the BTC chain; this likely will take a while.
The thing I'm starting to look at is adding in the liquidity trees. It's just a basic coding change, it shouldn't be too crazy, but free history filesize is important to have early IMO.
