That breaks essentially all turn restrictions.

it's not so few, it's 12,2% of all relations:

GoMap!! is limited in its capabilities to edit relations to reduce the chance 
of breaking anything. Without being sure, when splitting a way that is member 
of a relation, both parts continue with same membership. This might give 
undesired results in very few relations, so I think it is a safe approach for 
an app that doesn’t do editing of said relations.

relation membership is shown when you select a member and go to "tags", you
can select the relation, see the members and roles, and modify tags. You
can't (AFAIK) create relations, and from a quick test it seems splitting
ways of a turn restriction will result in inconsistent relations (two from
members in this test), i.e. if you split a way it will likely keep all
(new) members in the relation regardless of relation type (i.e. routes and
multipolygons will not break when splitting some of their members).

I'm sure complex geometric operations will likely destroy relations (e.g.
splitting a member, deleting one of the resulting ways, redraw it and don't
check or care for the relation), but for simpler usecases (draw short piece
of missing way, add nodes, move stuff, add or change tags) it is "the
almost perfect mobile editor".

When I first heard of GoMap, it was along with some criticism that it didn't 
handle the full osm data model and could mess up relations for example. I trust 
this has been sorted and GoMap is now relation-safe or even able to edit/create 
relations ?

In Android land I recommend Vespucci, which is ergonomic, full-featured, and 
Free (I've contributed a few translations and bugreports). 

I don't have any Apple stuff so I don't know how GoMap and Vespucci compare. Is 
there any cross-polination between the two ?

I have used GoMap!! since I hooked with the beta (under a different name to 
begin with). I have had some feedback to Bryce that have been incorporated. He 
have listened to the community for ideas, making the app more user-friendly and 
covering the needs of the different users. I agree wholeheartedly that it is 
good for adding data on the move, but for larger edits JOSM is still preferred 
editor.

completely agree with your assessment, just a small note: the name is GoMap!! 
(2 exclamation marks). ;-)

It's worth pointing out that adding a lot of geometry is still way faster with 
a mouse, but adding tag details on the ground and doing small geometric 
corrections (splitting ways for example ) is fantastic with goMap!! 
(autocompletion, tag copy+paste)

Good point, thank you for the addition.

There doesn't seem to be a (future) business model behind it. I wonder
if this keeping the source closed was a deliberate choice of the
author?

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

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.

I can't speak to the qualities of Go Map! but I think your review should
also mention the fact that this is proprietary software - it doesn't
cost anything but you can't look at the source. In that, it is different
from almost every other OSM editor widely used.
