The stock iOS calendar works just fine for basic scheduling, but if you religiously use Uber, Waze or Google Maps, Any.DO's Cal could be worth checking out. An update to the popular productivity outfit's brainchild brings integration with the three aforementioned services, which means you can now call a cab via Uber without leaving Cal, so long as you're in an area where the town cars roam. You'll also be able to navigate your way using Waze and Google Maps without having to launch them. As a nice bonus, Any.DO is introducing a new gifting feature that lets you buy straight from Amazon or Gifts.com from within the app itself. Cal is still nowhere to be seen on Google Play, but iOS users can score the refreshed application at the source.
Update (10/08/13): The folks at Any.DO have informed us that you can't access Uber without leaving Cal after all. There's actually an Uber link within the calendar that launches the request-a-ride app. The amended press release is attached after the break if you'd like to know more.
