I have a full set of Memory Map Ordnance Survey maps from an old version of Memory Map. Due to the completely unfair licensing these don't work with the current version of Memory Map and I'm not paying twice for the same thing (or is that three times - my taxes paid for the OS to create them in the first place ). I used to use MM Tracker on my S2. It no longer works on the S4 and it appears to have been abandoned. I have tried OS Atlas but it just doesn't work. Does anyone know of how I can either use my old Memory Map maps on my S4 or is there an alternative that doesn't mean I will have to pay a fortune for something I have already paid for?
