Introduction

Just like all my other projects, I like to combine my hobbies with my work. I like to listen to music, so I made a music app. I like play chess, so I made a chess app. *cough* I dont like to hand write my assignments, so I made a handwritten pdf gen app to write my assignments. I like to workout, so I am making a fitness app.

Why

I have used a lot of fitness apps in the past, I have liked some features of some apps and disliked some features of other apps. So as a developer, I thought to myself, why not build my own fitness app? So I decided to build my own fitness app that focuses on the features I think are important while being privacy focused and open source.

Features

Let’s talk about the features I want to implement in this app.

Non-functional requirements:

• Simple and intuitive UI
• Privacy focused
• Open source
• Cross platform
• Offline support
• Lightweight

Functional requirements:

• Display all exercises with important information with images and descriptions
• Track workouts and exercises
• Track progress over time
• Set goals and reminders
• Create custom workout plans
• Calendar view to see past workouts
• AI assistance for workout suggestions

How

Now, Lets start with the tech stack I am using to build this app. I am using React Native for the App because It is a cross platform framework and allows me to use all the benifits of great TS/JS packages and community support.

• Expo to routing and building the app.
• a sqlite database to store the data locally on the device for offline access and making it typesafe using Drizzle ORM for schema, querying and migrations.
• EAS to build and give OTA(over-the-air) updates for both Android and iOS.
• NativeWind for styling the app.
• Expo SecureStore to securely store user data.
• React Native Reusables for reusable components and utilities.
• All of this with TypeScript for type safety and better developer experience.

Demo

Here is a quick demo of the app I have built so far.

*UI is subject to change as I am still working on it.

Final Thoughts

I am really excited to build this app and I hope you are too. I have been developing and writing this app on my weekend free time after college, so it is a slow process. I will be writing follow up posts on the progress of this app and the features I am implementing. I will also be posting updates on my webpage and linkedIn page. If you want to see code for this app, you can check out the GitHub repository.
