Recall
Test yourself
Show answer only after you have tried. Retrieval beats rereading.
For students
The Learning Jet is a course and revision app. You recall notes on a scientific schedule, map ideas, and keep studying when the network drops. Memory is not a gift. It is a habit.

Miss a note and it comes back in a minute. Know it and it waits a day, then a week, then a month. That is spaced repetition, not cramming.
Recall
Show answer only after you have tried. Retrieval beats rereading.
Space
Short gaps, then longer ones, timed to the forgetting curve.
Connect
Mind maps and folders turn facts into a subject you can rebuild.
What you get
Notes come back at 1 minute, 3 minutes, 9 minutes, then 1 to 30 days — right as memory starts to fade.
Cards, multiple choice, and true/false force you to retrieve the answer before you see it.
Build maps of a topic and drop them into notes so you see how ideas connect, not only isolated facts.
Hide a word, play a clip, show a diagram, or open a link from inside a note.
Publish a course, nest folders like a syllabus, and revise one chapter or the whole subject.
Read a lesson first, then drill the notes that belong with it.
Anyone can build a course: folders, lessons, notes, mind maps, then share it.
Download a course, revise on the bus with no signal, and sync when you are back online.
Browse published courses, pull them onto the phone, and start revising immediately.
Built on research
Hermann Ebbinghaus · 1885
Without review, recall of new material drops quickly, then more slowly. Waiting too long means relearning. Reviewing just as the memory weakens is cheaper than starting over.
Cepeda, Pashler, Vul, Wixted, and Rohrer · 2006
A quantitative review of 839 assessments found that spacing study over time beats massing the same time into one sitting. The best gap grows with how long you need to remember.
Roediger and Karpicke · 2006
Taking a test on material produces better long-term memory than spending the same time restudying it. The act of retrieving is the learning event.
Download a course, hide the answer, and let the clock bring it back. That is how memory gets stronger.
