This is my first app where I did it completely on my own (previous ones I just helped out). Hard to say exactly how long, since I ended up spending time on it here and there over quite a few months (like all my projects lol), but I would say probably 4 weeks hard concentrating work in total, at a guess.
Argghh! I knew I should have spent more time spellchecking. I guess that isn't my strong suit. After seeing it so many times I kinda blank it.. thanks for the heads up.
