October 8, 2025

User reviews

Removed feature

New is the restriction that a radius can’t sweep a circle that covers more than half the earth. The app used to be able to do that; why the change?

Response from developer

It was a simple accident. In the future, please consider letting the developer know about the problem instead of leaving a rating that won't get read for many months.

Very handy

This is a very handy app, especially for triangulation. The developer was very responsive to constructive feedback, and the full version is even sweeter with some extra features.

Still needs work

It’s good in theory, but It doesn’t work very well. I tried to make a radius and changed the color and it won’t let me save the color and exit. Seems like it still needs work.

Response from developer

Hello, The December 2017 update broke that functionality, and I was unaware until late February 2018 when a gentleman from Australia notified me about this bug. In the future, please consider contacting the developer directly instead of leaving a message where it may never be read. We do not get notifications when reviews are posted... hence the 13 week lag in response. -Best Wishes, KW

Good to use with online dating apps

You know those online dating apps that show someone is 500 ft away, or .6 miles away, or even 1216 miles away... This is an ideal tool to give you an idea of where they might be, or at least see the possible locations.

The interface is a little quirky at first, but easy to get the hang of. One tip, select the unit of measure (feet, miles, etc.) before entering the distance. Once you change the unit it converts the distance to the new unit for you, which means you have to re-enter it. Not a big deal, but it gets me every time...
