UPDATE

I began my studies this Monday and will have very limited time during this week. This is a full-time study and leaves me little room to work 24/7 as I used to do. On the bright side, I am confident that I know where the lagging issue lies (within the AdMob SDK) and will be able to fix it as soon as I have an open hour or two. Furthermore, I received my Macbook and will be able to work out the iOS app as well at latest this weekend.

The on-site balance will also be topped up during the weekend or as soon as we have the next update fixing the lag and with an iOS release ready.
