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.

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.

All connection types can be tested over 1 Gb/s speeds !
2G, 3G, 4G, Wimax, WiFi & Ethernet speed test.
All WiFi technologies are supported. WiFi 802.11 a/b/g/ac dual-band, tri-band & quadri-band
All LTE technologies are supported. LTE, LTE Advanced dual-band, tri-band & more

Test your connection, diagnose connectivity issues and keep your Internet service provider and carriers honest!

I. It measures download speed
2. It measures Upload speed as well
3. Latency for gaming
4. Browsing speed (and (who doesn’t browse?!)
5. Video set up and amount of buffering
6. It creates a one screen report card of the test’s results on my iPhone and iPad Pro.
My Internet and WiFi are by Spectrum which promises download speeds to always be at at least 200 Mbps. My down load results are usually between 230 and 240 Mbps. Latency is around 20, and browsing is usually in the high 80s percentile (funny it was 91% for the first time today). Browsing has always been in the low 90s percentile and best of all buffering has ALWAYS been zero. Finally, if tracking results are important to you, the app’s final page is a one screen complete comprehensive report you can screenshot and store in a photo album.
I realize measurement protocols vary and I’ll leave debating this app’s methodology and algorithms to each user. No mater how you currently measure your cellular and WiFi device performance now, I recommend you give you this app a try. If it’s not for you, fortunately Apple makes deleting almost every app (including many of their own) a breeze.
Thank you for reading my review. My best wishes to all and please stay safe.

Speed tests

After using a number of Speed Test tools this one is by far the easiest to use and the closest to the real thing. Most speed test tools use Ping tests to give you some kind of information as to speed of your connection this one goes the distance by using actual phrases and returns a closer figure as to what's really happening with your upload and download speeds. I would most certainly recommend it to anyone needing a speed test tool on the fly!

Install to find out what the premium subscription is for??

I’m no stranger to nPerf and have several of my own servers running. It would be nice if this developer would spell out a few things, for example:

What features are limited (if any) without a premium subscription purchase?

Does the premium subscription purchase affect the tracking of performance data, collection, sharing, etc? In other words, does the subscription afford one the ability to perform tests with privacy?

Is there a mechanism to use one’s own nPerf servers for testing, and if so, is THIS data tracked and recorded as well?

In trying to find a testing app that provides data privacy for test results, there are just too many free apps (without ads even) and no IAP because of the lucrative market for the metrics. (I’m assuming this anyway)

Some clarification in the description on the function of the premium subscription and how it relates to privacy would be especially appreciated.

Thanks for making this app available; I hope to be able to use it.
