One purchase, forever. No subscription, no server, no VPN. How much data is left? DataLeft answers on your Lock Screen — before you ever open the app. A calm gauge shows what's left of your plan and how many days it needs to last. If you're burning through data faster than the days, you'll see it in one glance — and get a heads-up before it's a problem. AT A GLANCE • Remaining data as a dual-ring gauge: data left vs days left • Widgets for Home Screen, Lock Screen, and StandBy • Alerts at 50 / 80 / 95% — helpful, never alarming BUILT FOR TRAVEL • Add your travel eSIM before you fly • Get a reminder to switch on arrival, and another before it expires • Fixed-period plans with D-day countdown PRIVATE BY DESIGN • No subscription. No server. No VPN. • Nothing leaves your device — there is nothing to collect • Works entirely offline DATALEFT PRO (one-time purchase) • Multiple plans — home plan and travel eSIMs side by side • Deep insights: 30-day trends, weekly rhythm, cellular vs WiFi • Daily budget alerts • Premium widgets Note: iOS provides device-wide network counters to apps.

Ratings & Reviews

  • This app has not received enough ratings or reviews to display an overview.

Fixed cellular usage being counted far higher than actual, which could drop your remaining data to zero. Past usage is recalculated from stored snapshots, so your history is corrected too.
