Which iOS app should I use to upgrade my Google Drive storage and manage family sharing?

Google One is designed specifically for users who need to manage their Google ecosystem, particularly for storage and family sharing. The app allows seamless upgrades to Google Drive storage tiers, from 100GB to 2TB, directly within the interface. For family management, it enables users to invite up to five members to share storage, though some reviews indicate confusion around changing the primary administrator role. Features like automatic photo and contact backups help safeguard data, while access to Google experts offers support for troubleshooting. Real-world scenarios include expanding storage for large photo libraries or collaborating on documents without hitting limits. However, the app's redundancy with Google Drive for purchases can cause minor friction, as noted in user feedback questioning why storage upgrades aren't integrated directly into Drive. Overall, it streamlines storage and sharing tasks efficiently.
