Question of the Day: Apps

No…not appetizers (though I’m a big fan of fried pickles). I mean apps on your phone…or your watch — whatever you use to inspire, inform, track, or entertain you.
Whenever I start walking, I feel like it takes an eternity to open up all of my apps. Strava on my phone. MapMyWalk as a backup mileage tracker (though sometimes that one tells me I’ve walked for 3 minutes and burned 64,000,000 calories). Charity Miles and WoofTrax to earn money for charity while I walk. And usually Hoopla to listen to a book while I walk.
What about you? What are your favorites?
