About this app

Enter the Void. Get things done.

Phosphor isn't just an app I built; it's the tool I actually use.

? THE BACKSTORY
I built Phosphor because I survived the Korean SATs (Suneung)—one of the hardest exams in the world. Those years taught me exactly what you need to stay focused, and more importantly, what you don't need.

I was tired of switching between a timer app, a to-do list, and a music player just to study. It broke my flow every time. So, I combined them.

No ads. No clutter. And definitely no blinding white screens :)

------------------------------------------------------
? KEY FEATURES:

? The Focus System

Whether you swear by the Pomodoro technique (25/5) or just need a simple stopwatch to track your hours, it's all here.
• Timer & Stopwatch: Clean and simple.
• App Lock Protocol: Activate "Strict Mode." If you try to leave the app to check Instagram, Phosphor blocks you. It keeps you honest so you don't doom-scroll.

? Task Manager
A distraction-free list to dump your brain contents so you can focus on the work.
• Color Groups: Organize your chaos by subject.
• Pinning: Keep the "Do or Die" tasks at the very top.
• The "Ungrouped" Bin: For when you just need to write something down fast before you forget.
• Trash Recovery: Deleted something by accident? You have 30 days to get it back.

? Radio
Stop wasting 15 minutes picking the "perfect" playlist on Spotify. Just press play. You don't even have to go to another app.
• Lofi Hip Hop: For chill, steady studying.
• Synthwave: High energy. Perfect for compact sessions or last-minute crunches.
• Deep Ambient: Brown noise and rain sounds to block out the world.
• Integrated EQ: Tweak the bass to match your headphones.

? Local Music Player
Prefer your own MP3 collection?
• Offline First: Play your local files without leaving the app.
• Queue System: A straightforward way to manage your study mix.

? Motivation & Aesthetics
Productivity shouldn't feel like a spreadsheet. Phosphor is designed to look like a tool from the future.
• Meet Pho: He’s your little animated robot buddy. He reacts to your touches, keeps you company during long nights, and really loves coffee.
• Neon Visualizers: Watch the grid pulse to your music. It’s surprisingly soothing.
• Quotes: Save the lines that keep you going.

? Why Phosphor?
Most productivity apps are white, sterile, and boring. Phosphor is built for those who want their digital workspace to match their aesthetic. It’s dark-mode native, privacy-focused, and designed to get you into the "Flow State" instantly.

See what worked for me, and let's get to work right away.
