## What is Underlairs?

Underlairs is focus music for people with ambitious plans. Cinematic, high-intensity soundscapes engineered for deep work — press play, start the timer, and get more done in one session than most people do all day.

No lo-fi beach vibes here. This is music for masterminds.

FIVE SOUNDSCAPES, ONE MISSION
• THE LAIR — Your domain, your default soundscape
• BIG DESK ENERGY — Repeal societal expectations and break free
• SPACE PIRACY — Fly that spaceship into deep space like you stole it
• FLUENT IN FINANCE — Serious people doing serious things
• TOXIC INTENSITY — The details of your incompetence is not interesting

60+ original tracks. Zero interruptions. Music designed to keep your brain locked in, whether you're studying, coding, writing, or plotting something bigger.

BEAST MODE
A focus timer built for real sessions — not just 25-minute sprints. Track deep work sessions up to 24 hours. Start it, disappear into the work, and come back victorious.

STATS THAT KEEP SCORE
See your focus streaks and total time in the zone. Watch the hours stack up. Evidence of your inevitable rise.

• Completely free — every playlist, every feature
• No subscription, no ads, no account required
• Works offline — all music is on your device
• Background playback while you use other apps

Underlairs is free because world domination shouldn't have a paywall. If it helps you get things done, there's a tip jar inside — entirely optional, eternally appreciated.

### 5/5 — 바이브코더를 위한 최고의 앱

*2026-07-05*

요즘 페이블이 다시 풀려서 미친듯이 바이브코딩하고 있는데, 빠른템포의 음악으로 빡집중하면서 하나씩 일처리를 끝내고있습니다.
음악만으로 트랜스상태에 빠지는거같아요ㅋㅋ 강추합니다!!!

### 5/5 — Focus music

Great focus music for getting into deep work. It’s intense without being distracting, and it helps me stay locked in for long stretches. Love how there are different modes depending on the work I do.

### 5/5 — 매우 만족합니다

미니멀한 디자인, 긴장도를 주는 집중할 수 있는 음악!

### 5/5 — 픽셀 아트 디자인이 멋짐

*2026-06-18*

한 번도 본적 없던 테마의 앱! 색감도 존예인데 앱 개발자분인지 디자이너신지 한땀한땀 손으로 찍어만든 픽셀 아트 일러스트가 존예임.. 흔하게 아기자기한 느낌으로 예쁜거 아니고 쿨하게 예쁨 

일할 때 쓰는 앱인데 앱 키면 뭔가 일을 안하는 느낌을 받을 수 있음!!

### 5/5 — 앱 디자인 진짜쿨하고 멋짐

*2025-12-11*

가사없는 음악과 뽀모도로타이머가 조합된 앱인데 원래 따로따로 썼던 입장에서 집중하는동안 신나는 노래가 나와서 진짜 좋았음. 약간 영화주인공이 된것같은 bgm들이라서 신나고 좋음
