Data Usage: Cellular Tracker

Data Usage: Cellular Tracker helps you monitor cellular data and avoid unexpected overages. Create and manage recurring, prepaid, travel, physical SIM, and eSIM plans without mixing their individual usage totals. Review daily trends, network speed, remaining data, and high-usage alerts, or check your plan status from a Home Screen widget.

Premium adds smart forecasts, estimated run-out dates, predictive early-exhaustion alerts, full usage history, custom date ranges, unlimited plans, widgets, dark mode, and an ad-free experience. The app requires no account or VPN, keeping plan and usage records on your device. Because iOS does not provide per-app usage or automatically identify which SIM or eSIM used data, you select the active plan and can calibrate usage when necessary.
