Android: Boomerang has been one of our favourite email clients for a while. Now it's learning a new trick: location-based reminders for your email.
Users of Google Now have probably already gotten used to getting location-based reminders. Boomerang's new feature works on the same principle; you can set a specific email to leave you alone for now but come back and remind you again when you get to a specific place.
Reminders can be given for specific addresses (like when meeting a client) or broad areas (like the next time you go to a certain city). On top of the location awareness, Boomerang has a new customisable home screen widget for viewing your email without launching the app.
