I chose not to go with spider oak because of this app – SpiderOakONE Review

I have been using on desktop for a few weeks and does the job. But mobile so you cannot upload to hive, nor is it part of the “share” menu items available. For example say I want to upload from Photos? You can’t do it from an upload option in the app since it does not exist, nor can you “share” from the photos app. This means it only supports readonly functionality, and insecurely (as mentioned in the disclaimer when you log on). Not a good experience for a security-centric hosting service. Back to Dropbox.
