About this app

More than a simple speed test, nPerf brings you the best and the fullest mobile connection quality measurement tool up to 1 Gb/s speeds!

Full QoS test: In few seconds, test your bitrate speed, latency, browsing speed and video streaming quality on your mobile device.
Comparison function: Compare your results with those of others users and for each provider with a real time barometer.
Interactive map: Check network coverage and carriers performances in your area (in USA : AT&T, Sprint, T-Mobile, Verizon Wireless).
Network monitor: Stay informed on data speed in real time on the top of your mobile screen (status bar). Reports your data plan usage (in notifications).

A sliding menu (hamburger icon on top left corner) allows you to start every test separately:
- Speed test
- Browsing test - website loading speed
- Streaming test

All your results are saved in an history with all tests locations on a map. Easily share your results on social networks with nPerf sharing pictures which present a useful summary of your test. Customize your application by switching the background theme using the Settings.

nPerf relies on an homemade top technology and a wordwide high speed servers network which can deliver the bitrate you need for speed tests. With nPerf, you do not blow up your data plan: with many optimizations, testing consumes up to 2 times less data than competing speed tests. In addition, a data indicator will notify you if the monthly threshold you can set in the menu Settings is exceeded.

I live in a service sparse area with no service at my house. It does not start well with no service. It does start, which is a huge improvement over the other apps I use to find service locations. My chief complaint is the app gets one ping off a cell tower and then puts weak markers on the map for 30 seconds afterward when there is actually no service.

Enlightening! Unfortunately where I live, in the Arkansas backwoods the only two options are Cellular modems or Satellite modems for broadband. The cellular, even with a booster, was too slow for anything other than email and slow browsing. The Satellite service is satisfactory for non-highfinition streaming video and decent browsing and single person gaming. The App is simple to use and fairly quick. For me the comparisons were sad, as I was too slow to even fit on the graph.

Works really well, and I like that you can manually have it start tracking you and drive around with it while it gets signal readings every second or so. Plus it's great that the map gets updated with those results within a matter of just a couple of hours. The only problem is that the active mapping feature is kind of buggy. Sometimes when you signal changes from 5G to 4G LTE, the color marker shows orange for 4G, instead of red for 4G LTE. So it has a little trouble during active mapping.
