# Pho - Serverless Photo Gallery
> Own your photos. Your storage, your rules.

Pho is a serverless photo gallery app for iPhone that backs up photos directly to your own SMB, WebDAV, NFS, or Baidu Netdisk storage. There is no server component and no database - the storage filesystem IS the database, organized as YYYY/MM/DD/filename with a parallel .thumbnail/ mirror. Free with Pro upgrades (monthly $2.99 / annual $24.99 / lifetime $39.99).
