Under the Radar Grad Circle company Tungle is a web application that tackles a core problem – finding a time to meet despite the multiplicity of calendars holding your availability hostage.

Tungle just announced the release of a sister iPhone application.

After kicking the tires on Tungle’s iphone app, here are a few things I like:

1. I can suggest multiple meeting times (brilliant!)

2. I can let colleagues see ‘free/busy’ blocks, which means I don’t have to justify 2 hours going for a run along the Embarcadero – I can just block off the time as ‘busy.’

3. Tungle works to untangle the mess of calendars where I store info – including MS Exchange, 2 Google/gmail accounts with separate calendars, and my laptop Apple iCal.
