In short

GigaSave: Cellular Data estimates how much cellular data remains on an iPhone plan by subtracting device-wide network usage from a balance the user enters. It can limit selected video and social apps through Screen Time when the balance runs low or during chosen hours. Its standout feature is that no account is needed and plan data stays on the device, though the estimate may differ from the carrier's records.

About

See how much cellular data you may have left before your plan runs out. GigaSave estimates your remaining GB and helps you limit selected video and social apps when your balance gets low or during hours you choose.

HOW IT WORKS 1. In iPhone Settings > Cellular, check which apps have used the most cellular data. 2. Choose the apps you want to limit with Apple's Screen Time picker. Unselected apps stay available. 3. Enter the current remaining GB shown by your carrier and set your monthly allowance and renewal day.

GigaSave then estimates device-wide cellular usage from iPhone network counters and subtracts it from the balance you entered. See your estimated balance, days left in the cycle, and a daily usage guide. Set a low-balance threshold, daily limiting hours, or both. You can correct your balance using your carrier's latest figure at any time.

YOUR PLAN STAYS ON YOUR DEVICE No account is required. Your plan, balance, and app selections are stored on your iPhone and are not added to ad requests. GigaSave cannot see the names of selected apps or read per-app cellular usage.

ADS GigaSave may show a banner on the Home screen using Google services. The app remains usable if an ad cannot load. See the privacy policy for details about ad-related data processing.

IMPORTANT TO KNOW GigaSave does not fetch your carrier's official balance, change the Cellular Data switch, or guarantee exact or live tracking. The estimate can differ from your carrier's records, especially with dual SIM, shared or rollover plans, zero-rated traffic, reboots, or periods when iOS does not run the app. Notifications may be delayed. Daily time limits also apply while connected to Wi-Fi. Check your carrier's app for the official balance.

DATA CHARTS Compare estimated daily usage across the last 14 days with your daily guide. Review recorded monthly billing cycles against your allowance. The app cannot reconstruct daily usage from before setup.

Daily usage is estimated. When measurement intervals span multiple days, usage is distributed over time and may differ from the carrier’s official daily usage. Previously unmeasured data cannot be recovered. App locks also apply over Wi-Fi. To stop cellular data only, turn off the app in iPhone Settings > Cellular or Mobile Data.
