It's a niche product and people who search for those keywords usually already know what it is and that they need it. That's the beauty of organic search traffic. When I did paid ads, in the other hand, the best I remember was 2% click rate, then 20% trial download, then 10% purchase. At those percentages, a $2 cpm will cost me $5 per acquisition for a $9.99 app, so I have little wriggle room before it becomes cash flow negative.
