I know this is an old topic, but I prefer reviving old one rather then creating new one (the power of search )
To track my pump sites I've been using inSite for three weeks now... it's great.
I can add sites to it from my phone, iPad, and computer so it's easy to keep track of sites no matter where/when I change them. Also, I think it'll be really interesting to see if any site patterns form (nothing obvious yet).
I'm going to keep using it for a few more week before putting a review in the "apps" forum, but so far so great.
