I Built a Free Sleep Cycle Calculator

We all sleep every day, but many of us still wake up feeling tired — even after 7 or 8 hours. I used to experience this a lot, which made me curious about sleep cycles and how timing affects sleep quality.

While working on a small frontend project, I decided to turn that curiosity into a simple tool.

🛠 What It Does

This is a lightweight Sleep Cycle Calculator that helps you find better times to sleep or wake up.

You can use it to:

Find bedtimes based on when you want to wake up

Find wake-up times if you’re going to sleep now

Follow 90-minute sleep cycles

Get results instantly (no login, no pop-ups)

🔗 Try it here: https://sleep-steel.vercel.app

💡 Why I Made It

Many similar tools felt cluttered, ad-heavy, or locked behind apps. I wanted something simple, clean, and free.
The site does include a few ads to support hosting, but the focus is on keeping the experience fast and usable.

⚙️ Tech Stack

React

Simple state logic

Responsive UI

Deployed on Vercel

This project reminded me that small, focused tools can still be genuinely useful.

If you’re curious about sleep cycles, feel free to try it out 😊
