## Description
"Did I really study today?"
If you are giving a different answer to the same question every day, start by keeping a record.
StudyVault is a study tracker designed to help civil service exam candidates and other test-takers objectively measure their performance even when studying alone. It verifies studying while out and about with AI photo attendance, collects time by subject with an automatic timer, and even displays your condition for the day as a score through 90-day pattern analysis.
■ Key Features
· AI Photo Attendance Verification
Attendance is complete with just a single photo of a reading room, library, or study cafe.
The AI automatically determines whether the space is a study area. Only external study spaces are accepted; private spaces are not verified.
· Automatic Study Timer
Subject data for 136 types of exams, including civil service exams, professional certifications, and the CSAT, is built-in. When you select an exam, the subject list is automatically populated.
Measured time per subject is automatically tallied on a daily, weekly, and monthly basis. · Concentration Index (BRF/Patent Pending)
Analyzes study patterns over the past 90 days to display your current condition as a score.
Changes in concentration compared to yesterday are visible at a glance, and you can also check the 7-day trend.
· Slump Index (SCI/Patent Pending)
Detects slumps early using a relative indicator compared to data from peers.
It notifies you to take a break before burnout sets in.
· Amblyopia Detection (Patent Pending)
Automatically detects prolonged absence from your seat using a proprietary algorithm implemented with smartphone sensors and AI. Even if you get distracted by a phone call in the restroom or take a long lunch, the timer stops automatically if your accumulated absence exceeds approximately 20 minutes, recording only your actual focused time.
· Monthly Study Report
Monthly study patterns (attendance rate, time spent per subject, and concentration trends) are compiled, and you can directly compare your average study volume and start time with those of other students preparing for the same exam. AI trend analysis provides information on textbooks and study methods frequently used by students preparing for the same exam, allowing you to grasp at a glance "what other users preparing for the same exam are currently studying."
· Daily Learning LMS (Premium)
If you enable this in the settings, you can receive a summary of yesterday's study via LMS text message every morning.
Information included in a single message:
- Attendance results and time
- Total study time / Longest focused session
- Focus Index (BRF) · Slump Index (SCI)
- Personal goal achievement rate
- One-line comments based on study patterns
It is designed so you can check your performance from the previous day at a glance without even opening the app.
If you want to discuss your studies with your family without nagging like, "Did you study today?", you can set it to send the same summary to your guardian's number as well.
Students can turn it on or off at any time.
· Study Groups
Create groups with friends and colleagues to study together. You can see in real-time which subject a member is currently studying, and the rankings of popular subjects within the group are automatically tallied.
- Two group types — "Attendance Groups" that gather at the same time every day, and "Study Time Groups" that work together to meet weekly study time goals.
- Real-time member status — Whether they are currently studying, which subject they are studying, today's attendance time and verification location, and cumulative study time for today, this week, and this month are all displayed on a single card.
- Group popular subjects — Rankings of the subjects studied the most within the group based on today, this week, and this month are automatically tallied.
- Natural motivation — Status messages, ranks (XP), and AI attendance consecutive days are displayed together on the member card, providing mutual motivation through each other's pace.
It is designed to reduce the loneliness of studying alone and to provide motivation through the pace of others.
· Achievements and Ranks
From Pawn to Rook, Bishop, Knight, Queen, and King. Consistency is visualized through chess-motif ranks, and you can even collect hidden achievements.
· Today's Missions
Four missions are automatically issued every day at 5 AM — selected differently each day from a pool of 12 types, including "Study for 4 hours or more today," "Focus for 1 hour without a break," "Check in before 10 AM," and "Complete all personal goals."
They are automatically marked as completed based on your study and attendance records without the need for separate checking, and XP is accumulated for each completed mission, allowing your rank to increase.
· Attendance Calendar and Holiday Settings
Provides a calendar that allows you to check your attendance status (Successful, Late, Holiday, Unverified) for the past 14 days at a glance.
You can manage your condition by setting days off as holidays.
· 10 Color Themes
Gold, Blue, Green, Violet, Rose × Light/Dark combinations.
Change them to suit your study environment.
