Even has custom mapping features to give you full control over which contact fields you want to import on your phone Your imported Android contacts are kept on your phone and never synced with any Cloud service ever. With this app you will never have to give your contacts to Google, Yahoo, or any other Cloud service again. No need to install any sync bloatware programs on your PC. Your contacts will remain confidential to you. Note this is a one way import from your authorative CSV file.

App permissions are set generously to provide maximum compatibility.

It was replaced by a pipe beneath the ground. What now ...? Look up the logs for potential telephone jokers? No, then I'd rather draw a line in my map, where the final could be located given the formula and missing x ... But wait - Coordinate Joker will do it for you. Just enter the coordinate formulas and it will send the resulting waypoints to your preferred Geocaching app. With a bit of luck, one point will appear close to some path while the others may be far away. Then where would you look for the final? :)
