Shave does less than iMovie for $10 more. Maybe that's why it's not providing decent income? It's hard to compete with free, even more a good free app.
iMovie isn't free. It's $14.99. It's also slow as shit where Shave is fast as you know what - for a very specific type of editing.
Trust me, I've done the comparison of same editing tasks in both and I can do in a minute in Shave what takes 20-30 minutes to do in iMovie. It's the reason I wrote it in the first place. And good luck opening a DiVX or another weird codec in iMovie. Or editing an Mpeg-2/4 movie without having to re-encode. Or editing at all without re-encoding.
So, your customers are users with very specific editing needs, willing to pay for something they already have (disregarding performance), and/or that need to edit DivX or weird codecs. That sounds like a pretty tiny market compared to users who want a step up from iMovie; building a quality app for your own needs doesn't guarantee a market for it. That's just my point of view, you have the numbers.
