The short answer
YPT is built around measuring: a stopwatch per subject, a planner built from your study time, app blocking while the stopwatch runs, study groups and rankings by exam type. Lilo is built around company: you sit at a desk in a live 3D study room, study with friends in private rooms with a chat and compete in challenges like time goals and speed races. Lilo's free timer is a countdown, and Stopwatch and Pomodoro come with Lilo Premium. If you study better when other people are studying with you, without any camera, Lilo is made for that.

How they differ in practice
YPT, short for Yeolpumta, is built around measuring. You run a stopwatch for each subject, and the app turns that time into a study planner, daily, weekly and monthly stats, and a calendar that gets darker the more you study. The stopwatch can block other apps while it runs. Rankings are split by what you are studying for, such as university entrance, civil service exams or a language. In Korea, its App Store listing has about 48,000 ratings and sits in the top 10 of the Education chart.
Lilo is built around company. Instead of a column of numbers, you sit at a desk in a live 3D study room, like the Classroom, Café, Library or Seaside terrace, and see who is studying right now. Each person has a name tag with a country flag and their live study time. Lilo does not block apps and never uses your camera or microphone in rooms.
The timer is the biggest practical difference. YPT is a stopwatch first. Lilo’s free timer is a countdown with four scenes: Classic ring, Coffee, Sleeping cat and Rainy window. Stopwatch and Pomodoro modes come with Lilo Premium. What Lilo adds is company: while your countdown runs, you sit at a desk next to other people who are studying too.
Study groups vs study rooms
YPT’s study groups let you see whether each member is studying or resting in real time, through cam study or simple icons. Real-time rankings compare you with people working toward the same goal.
Lilo gives your friends a private study room, joined with a 6-character code or invite link, with a chat. You can also run study challenges together: a time goal, a speed race, a ranking battle or a streak. A friends feed and rankings show how everyone is doing. Streaks can be protected with XP you have earned, and the mascot Lilo changes outfit as you climb through 101 levels.
What switching looks like
Your YPT history stays in YPT, and Lilo starts counting from your first session. Lilo does not block apps, and it is a phone and tablet app for iPhone, iPad and Android, with no web or PC version. What it gives you instead is a room full of people studying with you, and friends you can study and compete with.
Most of Lilo is free: the countdown timer, live rooms, private rooms, your 3D character, challenges, streaks and a day planner with up to 2 tasks a day. Lilo Premium adds Stopwatch and Pomodoro modes, 30+ more timer scenes, the full music library, unlimited challenges and planning, and advanced stats. Lilo is available in 33 languages.
