Your page does very little to convince me to buy the app.
Think about it this way: most customers who will consider your app have already bought Numbers. So how is your app better than Numbers? Lua scripting sounds good, but it might not be enough. As for the rest of the page, your screenshots tell me very little about the app capabilities, while the "feature" descriptions are overly vague.
I will likely buy the app just hoping that it will work better (and faster) than Numbers, but I am not convinced - it feels like a die toss.
I am probably your target customer, so you might want to consider this.
I tend to use Numbers and iCloud all the time, because of the sync between desktop, iphone and ipad. The iphone might not be ideal, but I love that I can get at a spreadsheet easily when I'm mobile, and I don't always carry my ipad.
For me I wouldn't consider switching from Numbers without cross platform (desktop/phone/tablet) availability of my data.
