NetUsageLog vs Dual SIM Data Usage

NetUsageLog helps you stay on top of your Wi-Fi and cellular data, grouped by plans that match your carrier bill. • Custom plans: fixed date range (trips/short term), monthly billing cycle (auto rollover), and per-day quota (eSIM daily cards reset every day). You can also "Restart counting now", handy for an eSIM you activate abroad • Limit alerts: a notification at 80% and 100% of your cap • Today at a glance: today's Wi-Fi and cellular usage and current speed on the main screen, plus a 7-day chart • Widgets: small and medium on the Home Screen, plus circular, rectangular, and inline styles on the Lock Screen. Choose which plan each widget shows • Multi-SIM / eSIM: cellular data tracked per line, with custom line names • 17 languages: switch right inside the app About accuracy (an honest note): iOS doesn't let apps read usage in the background. Usage accrues only when the app records it (when you open the app, or when a Pro Shortcuts automation runs); usage in between is added at the next recording, spread across the days by elapsed time (an estimate), and alerts and widgets only update after a recording. If your phone restarts in the meantime, usage not yet recorded before the restart is lost, and the app tells you which time span was affected. Numbers are for reference — rely on your carrier bill. Per-app usage can't be measured (a system limitation). Privacy: your usage data stays on device, no VPN needed. No ads, no tracking. Upgrade to Pro (one-time purchase, unlocked forever): • Forecast & alerts: see when you'll hit your limit, set custom alert thresholds, and get notified when you go over today's suggested usage • Usage calibration: match the usage your carrier shows, so limits, alerts, and widgets use the calibrated number • Shortcuts automation: record automatically at a set time every day (no need to open the app) for more accurate usage across days • Advanced history: 30-day / 12-month trends, per-line analysis, and summaries • Data backup: export / import full backups so you never lose data when switching phones, or export an Excel spreadsheet

A data usage tracker for people who use two SIMs (eSIMs) on one iPhone. The Settings app doesn't make it easy to see how much each SIM has used this period, or how much is left. This app records your cellular data separately for each SIM, based on which line was in use at the time. ■ Great for • Using a work SIM during the day and a personal SIM at night • Juggling two personal SIMs • Tiered plans where you want to stay in the cheaper tier but keep going over ■ Features • Usage, remaining data and days left for each SIM • Forecast for the end of the period at your current pace • Comparison with the same point last month • Monthly plans with a reset day, and plans valid for a fixed number of days (30/90/180/365) • Tiered plans (price depends on usage): see your current tier and how much more until the next one • Set a goal tier to see a daily allowance and today's usage • Count limited-time add-ons (e.g. for travel) separately • Charts for the last 7 days, 30 days and 12 months, filterable by SIM • Home Screen and Lock Screen widgets • Optional: track Wi-Fi by network (SSID) too — handy for capped pocket or travel Wi-Fi • Notifications at 80%/100%, before the next tier, and when you're on pace to exceed your goal • Match the numbers to your carrier's app ■ How it counts The app reads the iPhone's cellular data counter and adds the increase since the last count to the line that was in use. With the widget added, it counts automatically every 15–30 minutes. Usage while you switch lines between counts is estimated, so numbers may differ slightly from your carrier's. Prices are estimates — check your carrier's app or website for exact usage and charges. ■ Privacy No account needed. Records stay on this iPhone and are never sent anywhere. The app does not look at the content of your traffic or which apps you use.
