Long time lurker, short time member. A few weeks ago I released my new Android app, SemiSilent, which allows you to whitelist contacts so that they ring your phone even when it's on silent mode. I've found it useful when on call or when my wife is working hours that I'm sleeping. I've already released a few updates, and I'm working on adding a few more based on feedback I've gotten.
I'd appreciate any feedback you'd have, whether it's feature requests, criticisms, thoughts on how to market, or any other wisdom you'd care to share.
