Cachesense is no longer being developed. The domain is no longer registered, and the forum has been deleted.
This I have just discovered, just before leaving on a long overseas trip.
Importing a PQ seems to include the corrected coordinates, but the app no longer sets the corrected flag. You can filter by the label from the PQ import though, so have a PQ which includes all your caches with corrected coordinates.
However, if you refresh the details, you go back to the original coordinates. This will happen if you view the cache details, so you essentially need to keep your phone offline.
An awful bunch of workarounds. Essentially, is time to ditch the app.
