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.

The most comprehensive informative, and accurate app out there to track & rate both wireless and mobile data services. With very comprehensive and detailed testing including data, web, and streaming performance. Plus coverage & performance maps right down to the street level. And the ads are very minimal and unobtrusive. Check it out. I use it all the time. Highly recommended.

App works great, I really appreciate apps that collect data to show users how strong or weak their carrier is especially when traveling. I map every time I hop in the car. What I have noticed is that the app doesn't collect data when you switch to another app yet still have this one running in the background. Battery optimization is turned off for this app too. 3/17 What have you done to this app. I have a constant ongoing notification that I cannot get rid of. Uninstalled.

New Google guidelines requires the passive mapping feature to show a notification. Of course you can disable it by tapping it and disable contribution. You can also access from inside the app in Coverage Map screen, contribute icon in the top action bar. There is no battery overusage.

I don't give 5 ★'s often but I do when I feel it's the best app in it's category or field. It does exactly what it says it does. The premium version is cheap. And it's seems to be very accurate. It stays updated from people's data they volunteer to share. It's easy and get user friendly. I'm happy with this app. (The only thing I would suggest is, making the 'finding of closest cell towers' a little more accurate and user friendly. I find it hard to find and click on towers near me.)
