What's New

Version 2.2

- Added support for landscape and iPad split screen.
- Corrected a bug that was introduced in the December update where editing some of a radii's properties would not trigger a refresh on the map. Thanks to Neil from Australia for pointing that out.
- Many low-level UI changes.

Supporting all layouts required significant back-end changes. Please report any issues that may have been introduced by emailing the developer.

Ratings and Reviews


Great app; Simple, unobtrusive measurement.

I use this app with local trade sites to find the extents of the distance I’m actually willing to travel, or to set a comfortable radius on a dating app. “Within X miles” type questions pop up deceptively often.

I originally downloaded the free version as a fun tool, but bought the pro version for it’s additional features and to buy the developer a cup of coffee.
