## What is GigaGuard?

GigaGuard tracks data across multiple SIMs (up to 20 profiles) in real time — no carrier login, no VPN, no account. Home screen, lock screen and Apple Watch widgets show remaining GB at a glance. Tip: add the widget to your home or lock screen — every time it appears, the app measures usage and re-evaluates your daily-limit alerts, making notifications more reliable even when you rarely open the app.

GigaGuard estimates your cellular and Wi-Fi data usage right on your device — no carrier account login needed.

FEATURES
- Monthly plans with a custom reset day and optional rollover of unused data
- Day-pass plans (e.g. a 7-day prepaid pass or travel eSIM) that start when you activate them
- Manual calibration: enter your carrier's official usage figure to keep estimates accurate
- Home screen and Lock Screen widgets, with a one-tap refresh button
- Premium: multiple profiles for separate SIMs, threshold notifications, and a usage history graph

Data usage is measured independently on-device and is an estimate. It may differ from your carrier's official figures — always check your carrier's app or website for exact billing.
