Been away for a couple of weeks, cant believe that the stupid ad is still there or back as the case may be.
I'm off to some other outdoorsy site as I will end up smashing up the laptop.
A note to Grangers and other advertisers on this site. I've bought loads of really expensive stuff after seeing ads on here and checking out the gear reviews on here. I have been driven away by this ad and wouldnt buy Grangers no matter what.
A bit of a whinge is ok for short term site niggles but this is taking the p~#s so I'm going to delete account ( If I can work out how to ! )
Been using viewranger on smartphones for the last 3 years. Bought the national parks maps at 1:50 and can confirm that these have been good enough, and as you mention, if you have the paper map at 1:25 you should really have no need to go to higher detail maps.
The 1:50 is ample for checking your position and indeed the higher detail on the 1:25 can sometimes be confusing with an overload of detail !
That said I did buy some extra credits and for a couple of places I have downloaded the 1:25, mainly when we're out looking for plane wrecks and other small targets. But 99% of the time the 1:50 is plenty good enough.
