Figured I'd offer the legal perspective on this question: For #1, how close to the "real word" is it? And how related is your app to the other one using the real word? Are you opening yourself up to a lawsuit from the company that offers the other app? For #2, why are there a decent number of apps that use that name in the description? Is it because the word (with the "e") is descriptive of what the app does? Is it descriptive of what your app does? If so, you'll have difficulty protecting your brand name. For #3, is what your app does related in any way to the generic product? Again, I'd be concerned about your ability to protect the name. Changing the first letter to another that sounds the same will do almost nothing from that point of view. I know you're really looking for more marketing-related feedback. But figured this could be helpful as well :)
