--Update--

It resulted on my own wish to add or alter nodes while being on the way. And it is the first OSM Editor on the iPhone. (See also my app „Leisure“, which searches for certain nodes around).

Now you can add and edit OSM data on the spot.

The application offers following functions: 

Localize your position. Search for any city (worldwide). Move the search target on the map.

Download the nodes around your or any position.

Edit, delete and insert tags in the node.

Copy and paste all tags from a node.

Tag dictionary for map featuers.

Create new node.

Upload the node to OpenStreetMap.

What do you need:

-an iPhone or iPod touch with:

-an internet connection

-to upload changes, you need an OpenStreetMap account

HowTo:

In info->settings enter your user/password for OSM.

Go to the position where you want to add or alter node (by localization or manualy).

Download the nodes around.

Select the node you want to alter or put crosslines at new position and select „New node“.

If you want to move a node, select the node, move the crosspoint on the map to the new position and select „move“. Then upload.

Alter tags by overwriting values.

Add tags by overwriting key and value. Or simply add.

Delete tags by swiping.

Choose „upload save“.

Go back to the main screen and download again to see your changes.

Have fun.

Things to come, if there is demand:

-Select nodes on map.

-Ways

-Send your wishlist :-)
