Upload anything from class. Get cards and a test back, each one cited to the page it came from, and a straight answer on where you will be by exam day.
Why this exists
Nobody fails for want of flashcards. They fail because they studied the wrong thing on the wrong night.
Knowing what to review, and when, is the part no study app answers. It is the only part we are really trying to solve.
Reading
Every card carries the page and the line it came from, checked against the document before it was saved. Swipe, or use the arrow keys.
Why does an aldehyde oxidise more readily than a ketone?
The carbonyl carbon in an aldehyde still carries a hydrogen, which can be removed to form the carboxylic acid. A ketone has two alkyl groups there and no hydrogen to lose.
Lecture 4, page 12 "Aldehydes retain an H on the carbonyl carbon and oxidise readily."
Testing
Same gesture, same deck. Pick an answer and see what the material actually says. These two are live, so try them.
Backward tilting of the lift vector caused by wingtip vortices is a primary mechanism for parasite drag.
Today, 10 minutes
Most schedulers ask which cards are due. That is the wrong question the week before a midterm. This ranks across every course at once.
| Course | Next deadline | Why now | Cards |
|---|---|---|---|
| MATH 240 | quiz in 5 days | 38 overdue | 38 |
| HIST 210 | assignment in 2 days | 4 overdue10 deadline soon | 14 |
| CHEM 101 | exam in 9 days | 5 overdue18 new | 23 |
History has ten cards that are not due yet. An assignment in two days pulled them forward.
CHEM 101 midterm, 9 days out
Spaced repetition already models how memory fades. Pointed at a date, it answers the only question that matters. Both figures are shown, because the optimistic one alone would be a sales pitch.
Keeping up means 80 cards over the next 9 days, 18 of which you have never seen. That is the honest cost of the second number.
Pricing
Try the whole thing first. We do not ask for a card to start, so nothing can quietly charge you on day 8.
| Plan | Price | What it means |
|---|---|---|
| Monthly | $9.99 | Cancel any time, in one tap. |
| Semester | $24.99 | Four months. Works out at $6.25 a month, and nothing renews over summer. |
Cancel in one tap from either the web or the app. The renewal date is always on screen, and no charge arrives without an email first.
