I'm planning on releasing a free version with 3 sounds and a 2.99 version with 10 sounds and timers and other features from the web version. I've never sold software before, so I pretty much have no idea what I'm doing when it comes to the marketing side of things. I have a suspicion the most lucrative approach would be based around in-app-purchases, but I really dislike those.
I'm building using Phonegap/cordova [2] which I have mixed feelings about as a toolkit. Phonegap media elements, which I'm using pretty extensively, are buggy and feature poor on Android, especially the older APIs. On the other hand, I'm nowhere close to being able to build an app like this natively, so I should be grateful the platform exists at all (!)
I'm working hard to make the user experience seamless, easy and smooth. I think the end product will be something I'll enjoy using.
