Excellent content

I'm really happy OS have made this app. I'll be visiting my home town of Bath next week and being able to get offline OS maps on my iPhone and iPad for hiking around the outskirts of the city is really great. Also having OS maps to plan with in advance is fantastic.

I'd love to see the overall app navigation simplified as it can be a little confusing in places. I think the use cases may need to be rethought a bit.

Also adding pins to the map would be great, in addition to only routes (connected by lines).

Also I'd make this 5 stars if you implemented iCloud sync of planned and recorded routes. I would like to plan routes on my iPad's big screen but take my phone with me on hikes.

Also I'm not sure why the app is 350+ megabytes. Surprisingly large?

Cost and altitude

By far biggest issue is cost: as an example, my bother lives near the intersection of 4 tiles, so walks we take mean buying all 4 tiles. I can access Google maps for free. Obviously, I would prefer OS maps, but for a single walk with my brother I think I'll stick with Google. I'd need to be doing regular walks in an unknown area to justify buying maps.
The other deficiency is that GPS real time data does not tell me my altitude/elevation as I walk up a hill. I want this also recorded to show a chart/graph of my walk's cross-sectional height.
