iOS: You have an insane amount of calendar options on iOS. But if you're looking for something a little different, Moleskine Timepage (yes, that Moleskine), focuses more on the timeline view and combines that with a weather forecast.
Moleskine Timepage is really all about the continuous timeline view. Once your calendars are imported, all your events are in one long, constantly scrolling timeline. There's no normal calendar view, so if that's something you prefer, look elsewhere. However, Moleskine Timepage does have a few killer features, including customisable transit time estimates (you can choose your mode of transport, car, public transit, walking or cycling), a useful notes section and tailored weather forecasts. Some users have been reporting problems with syncing, but we didn't notice any problems in our tests. It's certainly not an app for everyone, but if you're a big fan of list view style calendars, it does a lot right.
