The app blocker built for students
Your phone is the reason that two-hour study session turned into twenty minutes of actual work. Lock In blocks the apps pulling you away so you can study, finish the assignment, and actually retain it.

Block what derails you
Pick the apps that eat your study time (Instagram, TikTok, Snapchat, games) and Lock In silences them for the length of your session. With whitelist mode you can flip it around: block everything except your notes app and a textbook PDF.
Conscious friction, not a cage
Lock In does not trap you. Unlocking early takes a deliberate hold, just enough friction to make you ask "do I really need this right now?" That pause is usually all it takes to stay on the textbook.
Streaks that build the habit
Lock in once a day and your streak grows. It turns "I should study" into a daily habit you do not want to break, which is exactly how good study routines form during a semester.
Lock in with friends
Start a group session before a library cram, or keep a friend streak going so neither of you flakes. Studying with accountability beats studying alone, even when you are apart.
How to use Lock In to study
- Open Lock In and pick the apps that distract you most.
- Set a timer for your study block (try 50 minutes, then a real break).
- Hit Lock In. Your distracting apps are blocked until the timer ends.
- Earn minutes for the time you focus, and watch your streak grow each day.
- Studying with a group? Start a session so everyone sees who is locked in.
