Available for every Android device running Ice Cream Sandwich upwards


The Android version provides a full cross platform app for both tablets and phones. Its performance depends exclusively on the hardware specs of the device running the app. As a rule of thumb, newest Android phones will run nitroproc 2x slower than the latest iPhones, and around 3-4x slower than a desktop gaming PC. Old Android phones, will run nitroproc 5-6x slower than an iPhone and 8-10x slower than a gaming desktop.

All nitroproc scripts are fully compatible between platforms, you just need to take care the appropiate file paths are chosen properly according to each platform. For example if you are summarizying (aggregating) a file, for a PC the input file will generally be located on "C:/myfolder/file_to_sort.csv" whereas in an Android device you just need to put "file_to_sort.csv". Nitroproc will read and write the scripts from /Download. You can access the Download folder using a USB cable while connected to your PC/Mac.


The app can be installed from the Play Store (it is absolutely free with no ads).

Using the App

The main screen is divided into two parts: the upper part contains the .nitroproc scripts. The lower part contains the csv files that can be processed by nitroproc. When you install the app, it will contain sample scripts and csv files that you can use to test and learn how the app works.
The lower part contains the csv files. You can choose any of them, and view them row by row (bear in mind this works for monster files, although it might take some time to process)

Editing and running a script

Visualizing data

Just select a csv file from the list and you can visualize it (csv files are comma delimited files, quite standard in the data science industry). The total number of rows and columns will be displayed.

Visualizing the data. You can navigate the file using the buttons

Creating new scripts

Just select "New Script" on the main page. Enter the name that you want for that script, and your script will be added to the list. Naturally, you can then select the script and enter your code there.

Transferring files via USB or Wifi

Use a USB cable to transfer the files. You can alternatively use a WIFI app that transfers the files using your network. You can upload/download your scripts, and csv files. You can get WIFI apps here

There is a bug in some Android versions hiding the outputs generated by apps (for example nitroproc outputs and log files) when transferring files via a USB cable. The solution is to transfer the files using a WIFI app as described above.

Performance and benchmarks (sorting a 250MB file)

Go to Downloads and download the code.nitroproc script, and the sales.csv file. Use USB to transfer the files. In this example we will sort this .csv file containing around 4.5Million keys. This file contains 8 columns, some of them strings, dates and numbers. The performance on an iPhone 8 Plus is simply astonishing, you can see it runs in about 2.3 minutes, only 70% more than a medium-high end PC version (intel 4430 @3.00Ghz with a standard hard drive), which takes around 1.3 minutes. Bear in mind that an iPhone consumes around 6Watts/hour, and a gaming PC more than 250W/hour. The fact that such an incredible performance can be achieved with 50X less power is simply astonishing. As a final comment, note that both iPhone8 Plus and iPhoneX run using the same chip (A11 bionic), and older iPhones will yield considerable slower performance.

Nexus 5X 2015 - 15 minutes

iPhone 8 Plus - 2 minutes 29secs

PC Intel 4430 @3Ghz - 1 minutes 24secs
