Time is the dimension we're most familiar with for setting reminders. However, as time and space are so correlated in the universe there must be a way to set reminders based on the latter.
Astro allows you to set location-based reminders - which trigger the next time (or every time) you're there again. Use Astro to remind you of anything based on your location. Write notes and/or add photos to your reminders.
Ever want to see the photos and remember that place your child took their first steps? Or remind yourself how great the cheesecake was at a certain restaurant? Or how good you looked last time you were at the Eiffel Tower?
...Or even the list of items you need to buy at the grocery store?
