For students who keep meaning to start
Every day LockIn makes a short quest out of your own class material: the flashcards you’re about to forget, time locked in, the worksheet that’s due. Until it’s done, TikTok and Instagram send you straight back.
Free right now. Runs in your browser on iPhone, iPad, Android and laptops. You start with just your first name.
LockInLocked in until today’s quest is done: 3 things left.
Today’s quest
Try it: tick off the quest.
Pip checks in. He already turned this morning’s bio lecture into 12 flashcards and put a 25-minute review on your plan.
You open TikTok. Your phone takes you back to the Home Screen with a note: 12 cards and 25 minutes to go.
You lock in. LockIn holds the screen, and leaving it counts as a slip.
You hand in the math worksheet. Two answers need another look, so the timer keeps going.
Everything checks out. Your apps are open until 9.
Earned screen time
Choose your focus hours and what the quest asks for. During those hours your distracting apps stay locked until it’s done. If you make the rules easier, the change starts tomorrow, so you can’t talk yourself out of today.
On iPhone, locking uses a free Shortcut that takes about two minutes to set up.
Hand it in early
Do the worksheet right on the PDF in LockIn, or on paper and take a photo. Hand it in whenever you’re ready. If every answer is right, you’re done early. If not, you get a hint for each one to fix, and the timer keeps going.
Pip
Pip is a small green fish with a blue umbrella. In the afternoon and evening he looks at where you are: he turns a new lecture into flashcards, moves a session you missed, plans reviews before a test, then tells you what he did. You can talk to him anytime, or turn his check-ins off.
Your own material
Record a class and LockIn writes the notes. Add PDFs, slides, Google Docs and web pages. Then search by what you mean: “how do cells get energy from food” finds your notes on cellular respiration. Study sets are made from what you added, so they match your class.
Lock-in Drops
Make a room for your study group. Once a night, at a time nobody knows ahead, everyone gets the same message: 25 minutes, starting now. Join in the first three minutes. When half the room finishes, your streak grows. Rooms have no chat, just cheers.
For parents
On iPhone, app blocking uses Apple’s Shortcuts app. Turn on a Screen Time passcode only you know so it stays put. Calls and Emergency SOS always work.
For teachers and tutors
No ads, and we don’t sell your data. You sign up with a first name, not an email. Delete your account and everything in it from the app, any time.
Read the privacy policyYes. Right now it’s free to use.
Yes, in Chrome. To keep other apps closed during a session, use Android’s App pinning. The app blocker that works with the daily quest is iPhone only for now.
No. It checks your work and gives you hints. It never writes the answers or graded work for you.
Calls and Emergency SOS always work. For a session a parent or teacher assigned, you can ask them to let you out early.
No. You start with your first name. To use LockIn on another device, pair it with a short code, or save a passkey.
A parent or guardian should set it up with them.
