## What is Lumtime?

Exam prep，Study, Work,—  Lumtime Does It All!

Grad school exams, civil service exams, college entrance exams, IELTS, TOEFL... On the road to exam prep, the biggest fear isn't tough questions—it’s a lack of self-discipline. Lumtime is the ultimate all-in-one productivity suite designed specifically for students and professionals. We help you go from "wanting to learn" to "mission accomplished," with AI tools guiding your every step.

【AI Voice To-Dos, Habits & Countdowns — Go Hands-Free】
Driving, cooking, or too groggy in the morning? Just say: *"Remind me to study vocab at 8 AM tomorrow"* or *"Submit the report next Wednesday."* The AI instantly understands your intent and automatically creates timed reminders and to-do lists. Supports natural language conversations—jot down fleeting ideas anytime, anywhere.

【Pomodoro Focus — 25-Min Deep Immersion, Beat Distraction】
Based on the scientific Pomodoro Technique: 25 minutes of focus + 5 minutes of rest, with automatic daily focus time tracking. Top grad school preppers average 6+ hours of focus daily—your focus data doesn't lie. Supports custom focus durations, whether it's a 25-minute standard Pomodoro or a 50-minute deep work session. Auto-generates focus reports so you can clearly see your daily progress.

【Smart To-Do List — Never Miss a Task, Never Fail a Plan】
AI smart reminders automatically recognize task time and priority. Exam prep schedules, meeting arrangements, daily chores—leave it all to Lumtime. Supports sub-task splitting, tag categorization, and due date reminders. You can even record your own or a family member's voice as the reminder tone! Powerful recurring reminders (daily/weekly/monthly/yearly/custom). Supports Live Activity + Widgets + iCloud sync. The daily to-do overview tells you exactly what to do the moment you open the app, saying goodbye to "where do I start" anxiety.

【Habit Tracker — 21 Days to Build a Good Habit】
Vocab, practice tests, working out, waking up early... Check in daily and visualize your persistence. Continuous streak days, completion rate stats, and habit heatmaps make self-discipline visible. Supports custom habit frequencies (daily/weekly/custom) to flexibly fit your pace. When you see a 30-day streak, you won't want to break it.

【Countdown — Every Day Brings You Closer to Your Goal】
Grad school countdown, exam countdown, project deadlines... Desktop-level countdown widgets constantly remind you how far away your goals are. Run multiple countdowns simultaneously for different subjects, accurate to the day. Expired countdowns automatically archive into milestone records of your hard work.

【App Lock — Lock Out Temptation, Focus on the Now】
Block social media and games while studying to enforce strict focus. Supports Scheduled Lock (e.g., auto-locking distraction apps from 7 PM to 10 PM during study time) and Manual Lock for spontaneous focus needs. Locked apps cannot be opened—helping you truly achieve "phone in hand, mind in the book."

【More Productivity Tools】
Junk Cleaner: Clear duplicate photos and invalid contacts to free up space and stop phone lag.
Calculator: Scientific calculations + history log, an essential for exams and work.
Timer: Precise stopwatch + countdown, perfect for oral practice.
White Noise: Rain, ocean waves, café—create your focus space.
World Clock: See time zones at a glance for global meetings.
Currency Converter: Real-time exchange rates for business trips and travel.
