@hariette is working on ArtemisApp and there is a private beta first as it's all from the ground up. There's a lot of work Kbin needs itself to have 3rd party integrations as it is a little newer and younger than some of the alternatives.
@dansup is also working on another alternative too, kbam
Both of them are working hard on getting something to community is wanting. All in due time! You can join the /m/ArtemisApp magazine or dansup for following along with their progress. Getting involved with them seems to be the best way to help.
