I have tried outdooractive, but it has way to go to be the professional app that viewranger is, and is currently not a fit for purpose replacement. Please keep viewranger going until this is achieved or refund me the £100s I've spent on maps. re:your comment. update:Viewranger allowed me to store ALL mapping for UK on SD card. VERY disappointed that you have not listened to your userbase and continued maintaining Viewranger until Outdooractive caught up with it's functionality.
