#6: Good slogan look (absolut mobile): nice color and nice font. Levelapp: bad font, not enough unique. No uppercase letter required
#8: slogan: bad font and too small and compact. levelapp: nice font but not quite there yet. "Level" should stand out more than "app". And "app" is too dark Logo: good dynamic but want to see more ;-)
#7: good font but color sucks ;-) : either green or blue but not both. logo: good point with the shape. We would like to see something between #6 and #7 if possible.
Hello ! We don't need an icon in the case of the LEVEL APP
Could you make a LEVEL : small L - medium E and big V and after the mirror of that ? And same effort with the : APP. Thanks to make the letters respect a curve to give more harmony. We're expecting some inspiration for the slogan in the middle. Good luck !
