About NetUsageLog
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
What’s new
Version 1.6 · Updated October 24, 2026
Version 1.6 adds Lock Screen widgets and lets you choose which plan a widget shows. Pro gets Usage Calibration, and usage around device restarts is now counted more accurately. If you already own Pro, the new feature is unlocked at no extra cost. • Lock Screen widgets: a circular gauge shows how much of your limit is used, a rectangular widget shows usage / limit with a progress bar, and there's a one-line option above the clock. They show the usage the app last recorded and update after you open the app. • Choose a plan: touch and hold a widget → "Edit Widget" to pick the plan it shows. The default is "Automatic" (prefers a plan with a data limit). A medium widget set to a specific plan also shows today's Wi-Fi and cellular usage. • Usage Calibration (Pro): in "Edit Plan", enter this period's usage as shown in your carrier's app or SMS. Limits, alerts, and widgets then use the calibrated number, and new usage keeps adding up from there. It expires when the period resets. • Restart notice: if your phone restarted since the last recording, the app's main screen tells you which time span couldn't be read, because the system counters reset on restart. • More accurate counting: fixed a case where usage could be undercounted after a restart, and usage after a restart is now logged on the correct day. • "About Accuracy" now explains how usage while the app is closed is spread across days, and what a restart means. • Other minor improvements.
