Description by Oh Hyeon Kwon Written by the developer, not by AppBrain. Click to read.
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. DataLeft shows accurate totals for your device; per-app breakdowns are not possible for any third-party app.
