## What is Data Usage?

Know before your data runs out.

Data Usage turns your cellular counter into a clear plan forecast. See how much remains, whether your current pace is safe, and when you may run out—before the end of the cycle.

CORE FEATURES
• Track recurring, prepaid, travel, physical SIM, or eSIM plans you create
• Switch plans without mixing their individual totals
• Review daily trends and network speed
• Get accuracy and high-usage alerts
• Check remaining data from a Home Screen widget

PREMIUM
• Smart forecast and estimated run-out date
• Predictive alerts when your pace may exhaust the plan early
• Full history and custom date ranges
• Unlimited plan management
• Home Screen widget, dark theme, and no ads

Built for privacy: no account and no VPN required. Your plan and usage records stay on your device.

Accuracy note: iOS does not report per-app usage or automatically identify which SIM/eSIM plan consumed data. Select the active plan yourself. If iOS cannot recover usage after a restart or long gap, Data Usage will guide you to calibrate instead of showing false precision.

Premium renews automatically unless canceled at least 24 hours before the current period ends. Manage or cancel in Settings > Apple Account > Subscriptions.

### 1/5 — Flawed

*2026-07-24, version 2.2*

All those rave reviews have to be faked - it’s impossible to get past the adding a plan page - no way to enter the details and then dismiss the keyboard. Waste of time.

### 1/5 — Unable to create a plan

*2026-05-05, version 2.2*

No matter what I do, I am unable to create a plan to even try out the app. I can enter plan details, but the Save button remains grayed out.

### 5/5 — Полезное👍

*2026-05-02*

Лично по моёму мнению приложение удобное и выполняет бесплатный функционал пока что 30 минут использования🙂

Плюс: Настройка тарифа , графики траты интернет удобно использовать в отслеживании траты трафика🌐

Минусов; не нашёл🙂

Ну я советую приложение , хоть и оценка 3 вроде выполняет бесплатный функционал🙂👍

### 1/5 — Требует оплату

*2026-04-05*

Пробный период не работает. Требует оплату.

### 1/5 — Doesn’t work

*2025-11-01, version 2.1*

Great idea, but won’t allow me to add a plan and start it

### 1/5 — Not very accurate☹️

*2025-10-05, version 2.1*

{update} OK, i’ve given it a month. It’s really a total waste as far as accuracy is concerned. Seems to just be just a way to get ad revenue. Very Sad

data the bug needs a fix

### 1/5 — Not very accurate☹️
