Data Budget Tracker

Track mobile data and Wi-Fi usage with clear budgets for every network. DataSplit is a private data usage tracker and budget planner for mobile plans, Wi-Fi networks, prepaid SIMs, eSIMs, roaming, travel data and Personal Hotspot. It counts traffic from every app, entirely on your device. Enter your allowance, plan period and data already used. DataSplit calculates a practical daily target and shows whether you are on pace. HOW IT WORKS 1. Turn on data counting. 2. Set a daily, weekly, monthly or custom budget for your mobile plan or Wi-Fi network. 3. DataSplit tracks usage, divides what remains across the days ahead and warns you before your data runs out. ALWAYS FREE ⢠On-device mobile data and Wi-Fi usage counting across all apps ⢠Separate budgets for every saved network ⢠Daily allowances and custom billing cycles ⢠Usage warnings and local notifications ⢠History, charts, Home Screen widgets and a Live Activity ⢠Personal Hotspot usage estimates DATASPLIT PRO ⢠Automatic pause when a budget runs out ⢠Safety buffer when overages cost money ⢠Automatic or manual speed reduction ⢠Emergency stop that pauses data immediately ⢠Add extra data mid-cycle; DataSplit rebalances your daily allowance ⢠App blocking with Apple Screen Time Pro features require an in-app purchase. PRIVATE BY DESIGN There is no DataSplit account, remote server, advertising or analytics. Usage totals, budgets, Wi-Fi network names and settings stay on your device. DataSplit does not decrypt or analyze traffic content. iOS requests permission for a local VPN configuration so DataSplit can count mobile data and Wi-Fi traffic across apps. DataSplit is not a remote VPN service and does not relay traffic through a DataSplit server. While counting is active, DNS uses Cloudflare and Google public resolvers. These providers receive DNS queries and the device's public IP under their own privacy terms. DataSplit and its developer do not receive or retain those queries. DataSplit provides an independent estimate. Mobile and Wi-Fi providers may count usage differently, and Personal Hotspot usage is estimated. Always check your provider's official usage figures. DataSplit cannot guarantee that overage charges will never occur.
