Track Every MB. Stop Being Surprised by Your Mobile Bill. NetUsageLog helps you monitor your Wi-Fi and mobile data usage, track consumption based on your own plans and quotas, and receive alerts before you run out. Simple, clean, and completely on-device. Why Choose NetUsageLog ◆ Match Your Real Billing Cycle Set a monthly reset day (for example, the 3rd of every month), create custom date ranges, or use a daily eSIM quota mode that matches your carrier's billing cycle or travel data plan. ◆ Daily eSIM Quota Support – Perfect for Travelers Designed for eSIM plans that provide a daily data allowance. Automatically resets each day and shows your remaining data and recommended daily usage. Ideal for international travel. ◆ Separate Tracking for Dual SIM and eSIM Monitor each SIM or eSIM independently and assign custom names such as "Primary SIM" or "Travel eSIM". ◆ Usage Alerts Receive automatic notifications when your mobile data usage reaches 80% or 100% of your quota. Only mobile data counts toward plan limits; Wi-Fi usage is excluded. ◆ Visualize Long-Term Trends View usage charts and statistics over the last 7 days, 30 days, or 12 months. Analyze usage patterns by individual SIM line. ◆ Home Screen Widgets Check your current usage and remaining quota directly from your Home Screen without opening the app. ◆ Privacy First All data stays on your device. No VPN required and no usage data is uploaded to any server. Full backup and restore support helps you keep your data when changing devices. ◆ Multiple Languages Traditional Chinese, Simplified Chinese, English, Japanese, Korean, and Spanish. ◆ Important Note iOS does not allow apps to continuously monitor network usage in the background. Usage statistics are updated only when the app is opened. All figures are estimates and may differ from your carrier's records. Mobile data tracking requires a physical device. ◆ NetUsageLog Pro (Optional Upgrade) One-time purchase to unlock: Ad-free experience Data backup and restore Advanced history and statistics Stay informed.
