Hello Vladimir,
Thank you for the tip of Orux. I will give it a deeper try.
But what OSMAND offers you is more than adding some poi to a gpx track and editing it on the desktop. That for you can easily use OSMTracker for android.
OSMAND Benifits (http://code.google.com/p/osmand/):
- Online navigation with a turn-by-turn nav based on YOURNAV (http://www.yournavigation.org)
- Build in and editing existing POI (with your OSM account)
- Build in offline address searching (not sure this will work in hebrew)
Just with this tool I could add most of the following POI within one walk:

It would be almost impossible to add this with a tool like OSM Tracker for Android.
