Reverse Wherigo Solver?

[elrojo14]

I was just listening to the Geocaching Podcast last night and one of the Android app designers made a Reverse Wherigo Solver and is about to publish it in their app. Nic, can you throw in a Reverse Wherigo Solver? That would be pretty sweet. And before anyone accuses me of being lazy, the sheer fact reverse wherigos exist confirms anyone who hides one is lazy. We would just be returning the favor!

And by the way, I own like 150 reverse wherigos! LOL.

My preference is just to use one of the exiting online sites that provide this when passing in the 3 codes. I'm not sure there is much value in Cachly doing that within the app.

No, there are 1000 other important things that are priority before this.

Oh and I forgot. He set it up to where it scanned the cache page so you did not have to even input anything. Oh well. One can dream.

I love this idea. There is a series of 1000 reverse wherigos near Adelaide, SOuth Australia and the only way to currently set the solved coords is to copy and paste each number into a solver then copy and paste the coords back to the cache page. A tool to make this easier would be the most amazing thing ever

Hi there,

using tampermonkey and a script, you can solve it on the geocaching webpage directly. 

The code searches for 3 6-digit codes and calculates the coordinates.

You'll find a button in the top left corner of the Cache-page.

Unfortunately you have to click the button about three times to calculate the coordinates, insert the data into the personal notes, and correct the coordinates, but it is usually much faster than copy and paste...

Install Tampermonkey, Create a new empty script and paste the source-code

sometimes it also gets dates, then an old-school copy & paste has to be done...

Please take it, as it is, no warranty, no guarantee that it will run correctly. I calculate all Waldmeister WIG with this tool.
