About this app

Test weak networks on your phone. See your speed and traffic in real time.

PingPeek is a weak network simulator and network monitor for Android. No root, desktop proxy, or remote server required. Simulate limited bandwidth, high latency, and packet loss directly on your phone while monitoring upload and download speeds and traffic.

Developers and QA engineers can test app behavior under poor network conditions. Everyday users can observe data consumption and spot unusual usage spikes.

WEAK NETWORK TESTING ON YOUR PHONE
Does your app load on a slow connection? How does it respond to high latency? Can it recover after packet loss?
Adjust network conditions on a real Android device to test loading, request timeouts, retries, and reconnection without setting up a desktop proxy.

FREE FEATURES: LIVE NETWORK MONITORING
• Upload and download speeds refreshed every second
• Live speed display in the notification bar
• Device-wide traffic monitoring through a local VPN
• Normal monitoring preset: start without adjusting parameters
• No account or sign-up required

PRO FEATURES: ONE-TIME PURCHASE, NO SUBSCRIPTION
Weak network simulation
• Random loss: Bernoulli model for independent packet loss (0–100%), to test retries and fault tolerance
• Burst loss: Gilbert two-state model with adjustable average burst length, to test recovery during short periods of poor connectivity
• Latency and jitter: base delay and random jitter (0–5000 ms), with uniform, normal (Gaussian), and Pareto distributions for delay variation and occasional large delays
• Bandwidth limits: token bucket algorithm with independent upload and download settings (0–100 Mbps), to test loading and transfers on slow connections

6 built-in network presets
• Normal
• 2G Edge
• 3G UMTS
• Weak 4G
• Subway/Elevator
• Rural Wi-Fi

Traffic statistics and history
• Upload and download totals and session logs
• Traffic trend charts with day, week, and month views
• Historical sessions with full network parameters
• Floating speed widget to monitor live speed while using other apps

WHO IS IT FOR?
Mobile developers and QA engineers
Reproduce slow connections, high latency, and packet loss on a real device to check your app's resilience. Test wherever you are, without carrying a laptop or configuring a desktop proxy.

Everyday users
Check live network speeds and use statistics and history to understand traffic changes, observe usage while apps run in the background, and spot unusual spikes.

LOCAL PROCESSING, SIMPLE SETUP
• Network simulation and monitoring run on your device, without a remote proxy server
• Monitoring statistics and session records stay on your device and are not uploaded to a remote server
• No root or PC required
• Pay once to unlock Pro permanently, with no subscription
• Lightweight design with attention to battery use
• Supports English, Chinese, Japanese, German, French, and Korean

PingPeek — See your network clearly. Test weak networks with less setup.
