I think it could be a little more useful if you could add a note to the alarm about what to remember/ log where it is. What if you end up at bar #3 one evening and realize you missed the alarm? Which bar did you leave the card at #1 or #2? What time? etc. Maybe you don't have a location database ("Bar name #1", "Bar name #2", etc) but an arrow pointing to where the long/lat log was created (think a compass pointing to your object instead of north). Food for thought, I realize it would make your app much more complex than it is now; but I think you could make the UX simple & intuitive.
Last pointer- I am confused how you would use this to remind you not to leave your phone charging somewhere if the app is on the phone. I think you should change that example in your image to the grocery list one you mention in your copy.
