Momentum

🚀 Inspiration

I was inspired by my own productivity journey. I used to watch a lot of productivity videos on YouTube and relied on Chrome Pomodoro extensions. They helped, but I couldn't customize them to my specific timing needs. Later, when I started working out with YouTube tutorials, I noticed those sessions also used timed sets, like Pomodoro cycles for fitness. I wished I had an app that could notify me with sounds for each segment without needing to watch the whole video.

Then, during competitions and public speaking events, I needed to manage exact times for each part of a speech, for example, 2 minutes for the intro, 3 for development, etc. That’s when I realized I needed flexible sequential timers. So I decided to build an app that allows both cyclical Pomodoro timers and custom sequential timers.

🧭 What it does

Momentum is a productivity companion that lets you:

Create traditional or custom Pomodoro timers
Build sequential timers
Get alerts and sounds when a segment ends
Customize each timer with colors and emojis
Manage a built-in to-do list
View daily productivity stats
Enjoy simple navigation with a bottom tab bar

🛠️ How I built it

I used:

React Native with TypeScript
Expo Go for mobile and web compatibility
Expo Router for navigation
AsyncStorage for persistent local data
Expo Audio for sound alerts
Figma and Canva for UI/UX design
Bolt.New to speed up component building

🧗‍♀️ Challenges I ran into

Making sure timers could support both cyclical and sequential modes
Handling responsive design for mobile and web
Persisting data locally for timers, tasks, and stats
Designing a simple UX for flexible yet powerful timer creation

🏆 Accomplishments I'm proud of

Building a customizable timer ecosystem that works for productivity, fitness, and so much more
Creating an app that adapts to different workflows and feels intuitive
Managing segment labels, sounds, and timing logic smoothly
Making a useful tool that everyone can use every day
