Your apps stay locked
until you study.
Pick the apps you want locked. Every card you review earns you minutes on them.
Get the app
Rated 4.8 out of 5 on the App Store. Free to download.
The lock is the whole idea.
Choose the apps
Lock the ones you actually lose time to and leave the rest alone. You can change the list whenever you want.
Clear what is due
A handful of cards, picked because today is the day you would have forgotten them.
Bank the time
Every card you review adds screen time, and the occasional one pays five times over. Cash it in whenever you want it.
Drop in a PDF. Get a deck back.
A lecture slide deck, a photo of your notes, a recording of the class. It reads whatever you give it and writes the cards for you.
It knows when you will forget.
Look at the two buttons. Get it wrong and the card is back in minutes. Get it right and it disappears for days, then weeks, then months.
So you only ever see the cards that are about to slip, and your daily pile stays small even when the deck gets big.
144 charms, and no way to buy one.
Every deck wears one. Packs unlock as you review cards and hold a streak, so the ones on your decks are proof you showed up.
36 packs to open
Bunnies, bows, stationery, study buddies. Your decks end up looking like nobody else's.
The streak does the nagging
Two freezes for the days life gets in the way, so one bad week does not undo two good months.
Dark mode
For the studying that happens long after midnight.
Lock on the days that matter
Choose which days of the week the apps stay locked, and how much free time you get each day before the lock takes over. Set it once and forget about it.
No signal needed
On the bus, on a plane, anywhere with no signal. It catches up when you are back online.
Share a deck in one tap
Send a code to the group chat and everyone studies the same cards. Or import a CSV, including the ones Quizlet and Anki export.
Lock in.
Free to download. Pick your apps, make a deck, and let the lock do the rest.
