Hi
The POI density of FS varies wildly. For example here inf Finland there
is almost 100 POIS per square kilometer at the Helsinki capitol area but
at northern or eastern areas less than 0.1 POIs perm km2.
Quality of the POIs also varies.: i have noticed about one third of the
POIs are quite pointless (pun intended): private homes tagged something
else than private homes, lot of moving targgets not tagged so etc.
Accuracy is adequate to find out what is nearby but usually one needs good
O&M skills to find the entrance.
Openstreetmap is a different story. Although we are talking about
countries where a blind person can afford an iPhone and could
expect than joe Average can afford a smartphone too. However fro OSM
mapping satellite and aerial images are used a lot, also dedicated gps
loggers.
I cannot talk about OSM coverage globally but here in Finland when i have
compared OSM maps and Finnish national land survey maps OSM coverage is
quite good.

Well, for POI, FourSquare is reliant on its users checking in to places to
identify those places. In the US, many sighted people check in to places with
FourSquare. In NZ, on the other hand, some areas have many places marked whilst
other areas have only a few, or no places marked. Australia is better marked
than NZ, at least for large cities, but smaller towns are not marked very well
at all.
The same is true for the free user-identified street maps. Outside heavy
smartphone use areas where people are marking streets, nothing will be
identified. Therefore, even though Blind Square accesses worldwide data,
the data is not readily available outside the US, Canada, UK, and parts
of Western Europe.
Apple Maps and Google Maps actually access better map data. The same is true
for other general market GPS apps which are sold for specific countries.

Hi
With Blindsquare this should not matter because both of it's map resources are
globally available.
IMO there is market and need for blind-specific navigation applications.
Reason is very simple: sighted has only to look the visual map to get
information. For us there should be either quick commands to get needed
information or let the application babble all the time.
Personally i prefer the former approach.

Yes, this is part of what I am talking about. The blindness specific GPS apps
are primarily focused on US, Canada, and UK.
Apple Maps, Google Maps, and general market GPS apps cover many more countries.
With the blindness focussed apps, one pays significantly more for significantly
less.

Hi, my answer is somewhat dependent on what you said earlier so i?m replying in
the context. See below:

. Ariadne only announces your current street along with address ranges;
BlindSquare announces all this plus cross streets.
If it only did, sigh. Joe i agree with you so you?re not alone. I have never to
this day seen BS announce any cross streets in any shape or form whatsoever.
Points of interest? Yes it announces them, just not streets and intersections,
well it can announce streets provided it?s when it announces addresses which it
does in long intervals, that is BS is mostly silent when i need it, but when i
don?t need it, it blabbers on endlessly sometimes about addresses or streets
i?ve already passed. Filtering does nothing it only makes BS even more quiet.
I?m sorry and i probably will be flamed to bits for what i have said here, but
i don?t understand the hype of the app either. I thought it was me that was
stupid as usual, but after having tried BS in various situations i wonder if i
really could be this dense. Something isn?t working with Blind Square where i
live in Sweden. I am in contact with the developer to see if a fix can be made
to this.
