Quality needs improvement plus ideas

The quality gets from clear to fuzzy, which ruins a lot of my background designs. Im looking for other apps but sadly Im stuck with this. I also think kids desk should have a variety of colors to work with, dark gray is not black, Im sorry to say this, but its really not. There are adds which I understand are there, but dont think Im going to click it. Thankfully I can remove these horrid adds on kids desk. Im most likely not getting the full version, why waste money from a low quality app? This is a true and honest opinion, please dont let my review turn you away. Although there are setbacks, this is still the best option for background design (best is in kids desk).
Dont get triggered by this review, drawing desk lovers!
