NYN Fitness is a dynamic-recommendations workout app designed to provide users with the most relevant workout recommendations for their individual preferences and goals. It provides:
- 🚀 A simple, clean, responsive interface
- 📱 Many available platforms (web, Linux, Windows, macOS, Android and iOS via PWAs)
- ⚙️ Configurable attributes which change recommendation results
- 🖥️ A robust API for connecting to personal scripts/existing health components
- 🏃♀️ Easy self-deployment to customize workout libraries
NYN is covered under the GNU Affero General Public License, version 3.0 or later; you have the right to receive the source code behind any NYN deployment.
We maintain a deployment of NYN at https://nyn.amyip.net. You can simply log into that instance to use NYN!
If you want an app version:
The specific web browser you're using changes the specific method; however, most mobile web browsers will let you install PWAs (which NYN is shipped as). All of these require you first visit the web deployment; however, you do not need to log in.
For Chrome on Android, click the kebab menu (three dots, top right corner) and look for "Install app". This will put the app in your app drawer, and from there you can place it on your home screen.
For Safari on iOS, click the Share button, and then click "Add to home screen". You can then configure it to your liking.
We currently only ship a "portable" version of NYN for Windows. You can find this in the most recent release on the Releases tab. Portable versions execute as a file, but don't "install" to your system; this may be more inconvienent. If you're on Microsoft Edge, you can use the web version by clicking "Install app" to install it as a PWA; this is still largely equivalent.
If you'd like to see a properly-installable version of NYN for Windows, contribute to NYN by submitting a Pull Request.
NYN for macOS is shipped as a Zip archive in Releases. Download that archive and double-click on it in Finder to extract it. From there, you can take the NYN icon (appears as an atom on macOS) and drag it into your Applications folder; this will install NYN. If you want to use the app in portable mode, you can double-click it, and it will still execute correctly.
If you use a dpkg-based distribution (like Debian, Ubuntu, and Linux Mint), you can use the .deb file in Releases.
If you use an RPM-based distribution (like Fedora, RHEL, CentOS, Rocky, and SUSE), you can use the .rpm file in Releases.
We don't ship any other packaging formats currently for NYN, and we recommend using
the web version. Some browsers may allow you to install the app to your system as
a PWA; this is known to work on Firefox, through extensions, and natively on Edge.
You can also download the source code and use the electron folder to run/package
natively yourself.
We do not currently have support for desktop apps on any other operating systems. You can use the web version, or use a browser with PWA support to install as a PWA.
Prerequsites:
- A MySQL or MariaDB database set up with the tables in the
setupfolder. - A Linux server with modern build tools (gcc/g++), Python 3, nodejs/npm, and Make.
- (Optional) a Cron implementation (such as Cronie) that supports
@weekly
First, clone the repository:
git clone https://github.com/amyipdev/nyn-fitnessThen, use the interactive generator to make a config file:
cd nyn-fitness
python3 gen_config.pyNow, run the server (perhaps in a terminal multiplexer like tmux):
./run.shTo keep your database size reasonable on large instances, install the crontab:
cron/insert-crontab.shYour NYN instance will not initially have content. You can add workouts using:
python3 setup/input_workouts.pyNYN currently does not ship with SSL. However, you can use a reverse proxy (we recommend NGINX) to enable SSL support with free certificates from Let's Encrypt.

NYN is the Fall 2023 term project for the aforementioned authors in Swayam Pati's CPSC 362 at California State University, Fullerton. This does not dispel the copyrights retained by the individual authors, who retain sole copyright and all rights as expressed under the AGPLv3.
We chose to make a fitness tracking/workouts app to help promote health and fitness on campus, as we found many of the existing solutions (like Sworkit) to not meet the needs of the CSU Fullerton community. NYN is also one of the few content-based solutions to be 100% free (as in freedom) software.
The name comes from our inability to find a name; NYN is short for "not yet named". The acronym eventually stuck due to its palindromic nature.
We also used this opportunity to learn frameworks we previously had no experience with, like libpython and Svelte. These ended up being critical to the project. Svelte has saved signficant amounts of development time, and contributes heavily to incredible site performance, even on low-performing machines. By writing our mathematical code in C++, we were able to reduce total API latency across the entire stack (including network latency!) to an average of 7ms, even for recommendation requests; in fact, the average non-database-hitting request takes up 4ms, and the average database-hitting request takes 5ms, meaning processing the entire workout database to generate recommendations only takes ~2ms of additional processing time! (Times were measured on a Ryzen 7 7700X, real deployments may be on a 3700X or less)
Optimization has been a critical part of the project. Our current infrastructure uses AVX2 to optimize vector computations for recommendations; most of our mathematical code gets executed as straight AVX2 instructions with no interruptions that could cause speculative execution misses to occur. Given the size of our vectors, we also have the ability to scale well to AVX-512 hardware.
