Demon Time
Read full descriptionHide full description
Every hour you grind feeds your demon. Demon Time is a focus timer that transforms your practice hours into a dark, addictive progression system. Track time on any skill or project, watch your demon evolve through 8 ranks โ from a tiny Ember to a fearsome Demon Lord โ and maintain your Possession Chain to prove you're built different. Inspired by the 10,000 hour rule, Demon Time makes the long grind feel rewarding from day one. Each session is a Ritual. Each project is a Demon you're raising. Skip a day and your demon starts rusting. Neglect it for a month and it begins to starve. But show up consistently? Your demon evolves, your rank ascends, and you earn Souls to customize your experience. SUMMONING CIRCLE TIMER Start The Ritual and watch the summoning circle track your session with rotating runes, glowing progress arcs, and floating ember particles. This isn't a boring countdown โ it's a ceremony. 8 DEMON RANKS Evolve from Ember (0h) to Demon Lord (10,000h). Each rank transforms your demon's visual form โ growing horns, wings, orbiting runes, and reality-warping effects as you ascend. LIVING DEMON MASCOTS Your demon lives inside the summoning circle. It thrives when you grind, dims when you slack, rusts when you disappear, and starves if you abandon it. Feed it or watch it die. POSSESSION CHAINS Maintain your streak by logging at least one session every day. Watch your chain grow from Sparked (3 days) to Immortal (365 days). Break it and feel the pain. SCROLLS (INSIGHTS) Discover when you're most productive, which sessions hit flow state, and how your hours compare week over week. Data presented as ancient wisdom from the underworld. RELICS (ACHIEVEMENTS) Unlock 30+ achievements โ from First Blood (1 hour) to Dawn Breaker (session that starts before midnight and ends after 5am). Each relic earns Souls. SOUL ECONOMY Earn Souls through grinding and spend them on cosmetic upgrades โ summoning circle skins, timer animations, ambient soundscapes, and profile flair. TRUE DEMON TIME Sessions between 12am and 5am earn bonus Souls and a special visual mode. The app knows when you're on demon time. Built for developers, musicians, artists, writers, students, and anyone tracking their 10,000-hour journey. Dark mode only. No ads in the free tier. Your grind deserves better than a pastel timer. Feed your demons. Keywords : focus,timer,productivity,hours,tracker,10000,pomodoro,streak,grind,study,practice,skill,habit,dark
