# 6 & 7 - too"nuclear" looking, logo is too strong; like the two colors of #6 better than the shades of red #7 # 8 & 9 - like the unity feel of the sphere, like the two colors of SNAPP; Like horizontal treatment of #8 better than verticle of #9
The points that we really like are your use of the red SN with the grey APP. remove the grey background all together.
Try something totally different for the icon. Think, complex software transactions that have become very simple... many to one.... dreaming of the future...
