So, today we got the first paid client. I've been busy with other things so I've neglected this project. But this may be the thing needed to get me started again on promoting this more.
In total it has more than 170 freemium users. Also everything is ruining smoothly, I didn't had to release an update in a long time, now that I think about it, I think I've lunched it too late as after lunch only a few small changes were needed.
