An app called Perfect Pocket on google play is the new way to go: https://play.google.com/store/apps/details?id=com.soapsign.perfect&hl=en
Also someone who doesn't have an android device could install something like LeapDroid on their computer which is an android emulator, then install Perfect Pocket and use it on there. http://www.leapdroid.com/

It is an android app. Not very popular but works perfect for me.
edit: The app has been removed from the store since I posted the link. Still is working for me, idk why it has been removed.
This app is back on the Google Play store. It just went up moments ago while I was trying to find the APK.

Looks like they had to remove the Pokémon trademarks in order to keep it on the store. Thus, it's a whole new app.
pgnexus.gg is your savior. Other than that, check out Perfect Pocket (https://play.google.com/store/apps/details?id=com.soapsign.perfect) or GoStats (https://www.apk4fun.com/apk/101405/) for Android.
Perfect Pocket is still functioning: https://play.google.com/store/apps/details?id=com.soapsign.perfect
There's an app just out of China that was mentioned in another post that does the same data pull: Perfect Pocket
It was just added back to the Google Play store less than an hour ago.
