Branding for new iPhone app

Working on a logo for an location-based check-in iPhone app designed for teenagers and parents.

I'm running with the theme of everything being "OK" (user has to 'check in' to let their folks they're 'okay'. The hand gesture for ok is the finger and thumb connected, paired with the counter space as a location marker round off the two major features of the product.

Thoughts? Comments?
