A new calendar app without an implicit bias towards iOS is always worth celebrating. Airbridge certainly ticks the aesthetically-pleasing box and I quite like the idea of just defining time blocks as you go, rather than fitting things to a grid (which so often isn't flexible enough). Colour coding also looks great. No mention on whether you can sync calendars between accounts (a feature that would be incredibly useful to me), nor how much it is likely to cost once out of beta, but one to keep an eye on.
