I have one specific equestrian app on my iPhone and that is the smartpak blanketing app. I don't always follow it, but it's fun to see what they recommend. It's also good source to check the weather. Believe it or not, we are heading in to blanketing season.
In case you were wondering, Emi is now wearing a size 75". Where'd my baby go!?
For trail riding I like to have something that will track distance, speed etc. I have been using Map My Run which was working well for a while. In the past 6 months or so it has been taking forever to load, and shuts down when I'm about a mile in to a ride. I thought perhaps it was a service issue but it happens regardless of where I ride. I can re-open it and it's still tracking, but the time/distance doesn't ever seem correct. So....I'm on the search for something else.
What equestrian apps do you use? Do you have one that is a must have?
