> - Objects are moved by dragging a handle next to the object, rather
> than the object itself. This way, you're not obscuring the placement
> of the object.
> - When drawing a new line, a subtle animation is shown whenever you're
> about to connect a node to another node or line.
> - The application does not permit the manipulation (such as
> straightening) of objects (partially) outside of the view.
> I found that entering the results of my surveys straight in Go Map!
> saves me a lot of time, and additionally improves the quality of my
> data (since one data manipulation step is cut out, and I can verify
> results immediately).
> Of course, even with Go Map!, accidental data errors might be
> possible. And repetitive actions, or manipulation of large areas with
> many notes, is perhaps still easier on a desktop computer. But
> overall, I find Go Map! a large improvement.
> And an additional bonus: whenever passers-by ask you when this map
> you're creating can be viewed online, you now can tell them: "in about
> two minutes".
> I'd recommend every iOS user to give the application at least a try.
> The application can be downloaded here:

I have been (infrequently) using this for years and I agree about its

In particular, I like how I can position objects by matching aerial
imagery to what I'm seeing in the real world at the same time.
