About this app

Lock In is a study app and focus timer that turns your study sessions into visible progress.
Start a focus session, track the time you spend on each subject and build a study routine you can maintain. Lock In is designed for high school students, university students, exam preparation, language learning and independent study.
Focus on what matters
Create your own subjects and activities and use the study timer to record every session. Study, read, practise, prepare for an exam or work on a personal project while Lock In keeps track of your progress.
Track your study progress
Review your study time by day, week, month, 90 days or across your entire history. See how much time you spend on each activity, review your sessions and understand your study habits through calendars and progress charts.
Grow your Effort Garden
Every focus session contributes to your progress. Plant seeds, grow trees for your subjects and build a garden that represents the time you have dedicated to studying. Unlock new variations and turn consistency into something you can see.
Study with other people
Create study groups, add friends and share your routine with other students. See who is studying, taking a break or offline and stay motivated with people who are working towards their own goals.
Organise your study routine
Lock In includes useful tools for your day-to-day study:
- Calendar for tasks and events.
- Journal for reflecting on your progress.
- Scientific calculator for study sessions.
- Custom activities for each subject or project.
- Statistics to understand your habits.
Make your focus space yours
Personalise your experience with music from your device, playlists, visual themes, gardens and animated avatars. Your avatar changes during your session and reflects different stages of effort, rest and concentration.
Built for real study routines
You can continue recording your progress offline and sync your data when your connection returns. Your account helps you keep your activities, sessions, statistics, garden and personalisation across supported devices.
Lock In is more than a timer. It is a study space to focus, track your progress and study alongside other people.
Enter. Focus. Progress.
