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

Pho is a serverless photo gallery app for iPhone and Android that backs up photos directly to your own SMB, WebDAV, NFS, Google Drive, Baidu Netdisk, or any S3-compatible 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 $1.99 / annual $19.99 / lifetime $39.99).
