DiskState makes your iPhone storage status quick to read and easy to understand. Storage at a glance - Total, used, and currently available capacity - A clear ring showing the percentage used - A simple status that highlights low free space - Apple's estimated writable capacity for new content Home Screen widgets - Small and Medium WidgetKit widgets - Check current storage without opening the app - Refreshes on the schedule managed by iOS Clear, honest measurements DiskState uses Apple's public file-system APIs. For privacy and security, iOS does not let third-party apps read storage usage by other apps, Photos, or System. DiskState does not invent those categories. For a detailed breakdown, use Settings > General > iPhone Storage. Privacy Storage values are processed on your device and are not sent to a developer-operated server. No account or system permission is required. Activating the widgets for the first time requires watching one rewarded ad. Once activated, you do not need to watch it again.

Verdict

The call

The clearest difference is in-app purchases: Storage Widget at none against Gantt Chart's 1. Gantt Chart's advantage is ads (none vs shown) and update cadence (every 2 days vs every 2 weeks). On price, device support and iOS requirement there is nothing between them.
