About this app

Take control of your internet traffic with a simple VPN-based network control tool.

Dev Mock helps you monitor upload and download activity in real time and switch network behavior instantly with one tap. Use it to test app behavior, reduce data usage in specific scenarios, or temporarily limit traffic when needed.

What you can do:
- View live upload and download speed
- Track total data used during each session
- See session duration and traffic history
- Choose between 4 traffic modes:
1. Allow All
2. Block Upload
3. Block Download
4. Block All

Built for practical control:
- Works through Android VPN service (no root required)
- Fast mode switching from a clean dashboard
- Lightweight design focused on core network controls

Privacy-focused approach:
- Does not inspect message/content payloads
- Does not log browsing content details
- Designed to focus on traffic control and usage visibility

Dev Mock is ideal for developers, testers, and advanced users who want clear, direct control over mobile network behavior.
