Viewranger is a great 5 star app, or was until they took away the OS maps and tried to force you into the very poor outdoor active app. Bad decision Viewranger! Update. To force users to make the move to OA, they are stopping all support to Viewranger. Not sure how OA can keep ignoring the review's and feedback and keep spouting the 'we are making things better OA is great' rubbish. 1.5 stars OA. Get real and reinstate all functions to Viewranger until you can get to a like for like product.
