I got tired of not having an app for use on Android to track all my pins, so I conned a developer friend of mine into helping write one. It's now up on the Play Store for your use if you'd like.
The app can be a little fragile in some spots. When you first open it up, go to the settings and click "Sync Config". That'll grab all the pin data. Don't interrupt it, or it'll stop in the middle and you'll end up with like 20 pins. If that happens, close the app and restart the Sync. Whenever new pins are ready, you'll be able to pull them in by simply doing another "Sync Config".
Hopefully you'll find it useful. -https://play.google.com/store/apps/details?id=net.galliard.galang.collectionstracker&hl=en
