Spaced Repetition is backed by a century of science and some of the smartest people on the planet.
Here's what they say, in 35 quotes:
"Memory ceases to be a haphazard phenomenon, something you hope happens: spaced repetition systems make memory a choice."
"The spacing effect is one of the most dependable and replicable phenomena in experimental psychology."
"The long-term advantages of distributing practice sessions over time have been demonstrated repeatedly for more than a century."
"Repeated retrieval with long intervals between each test produced a 200% improvement in long-term retention relative to repeated retrieval with no spacing between tests."
"There is a mountain of evidence suggesting that spacing study time leads to better memory of the material."
"Periodic practice arrests forgetting, strengthens retrieval routes, and is essential for hanging onto the knowledge you want to gain."
"The spacing effect is one of the oldest and most reliable findings in research on human learning."
"Hundreds of studies in cognitive and educational psychology have demonstrated that spacing out repeated encounters with the material over time produces superior long-term learning, compared with repetitions that are massed together."
"The empirical evidence for the benefits of distributed (over massed) practice is overwhelming."
"The positive effects of spacing on long-term recall are large and robust, and have been demonstrated in a variety of domains."
"Delaying of reviews produces an actual increase in the efficiency of learning."
"Spacing presentations of to-be-learned information across time, rather than massing them, can have a very large positive effect on long-term retention."
"[Spaced Repetition] offers something like a 20-fold improvement over (say) ordinary flashcards."
"Our experiments demonstrate that powerful spacing effects occur over practically meaningful time periods."
"The general conclusion is that the best retrieval schedules are those that involve wide spacing of retrieval attempts."
"Once you review, you can review less often. So I went on just to measure how often we need to review. Once I measured optimum intervals for review, I started using them in real life and it was just an avalanche of ideas for improvement since then."
"It sounds unassuming, but spaced repetition produces impressive results. [Students] who relied on a spaced approach to learning had nearly double the retention rate of students who studied the same material in a consolidated unit."
"The technique is called distributed learning or, more commonly, the spacing effect. People learn at least as much, and retain it much longer, when they distribute—or 'space'—their study time than when they concentrate it."
"Increased spacing of training sessions greatly enhances long-term retention of vocabulary."
"Whether students engage in retrieval practice over days, weeks, or months, research shows that any spacing is better than none."
"Left to itself every mental content gradually loses its capacity for being revived, or at least suffers loss in this regard under the influence of time."
"When retrieval practice is spaced, allowing some forgetting to occur between tests, it leads to stronger long-term retention than when it is massed."
"More than 100 years of distributed practice research have demonstrated that learning is powerfully affected by the temporal distribution of study time."
"Students will retain knowledge and skills for a longer period of time when they distribute their practice than when they mass it, even if they use the same amount of time massing and distributing their practice."
"Research shows that a delayed review typically has a large positive impact on the amount of information that is remembered much later."
"When you space out practice at a task and get a little rusty between sessions, or you interleave the practice of two or more subjects, retrieval is harder and feels less productive, but the effort produces longer lasting learning and enables more versatile application of it in later settings."
"The timing of learning sessions can have powerful effects on retention when study time is equated."
"We rated two strategies—practice testing and distributed practice—as the most effective of those we reviewed because they can help students regardless of age, they can enhance learning and comprehension of a large range of materials, and, most important, they can boost student achievement."
"The longer intervals yield substantially higher recall in spite of their adverse effects on acquisition."
"When learning is harder, it's stronger and lasts longer."
"Using memory changes memory—and for the better. Forgetting enables and deepens learning, by filtering out distracting information and by allowing some breakdown that, after reuse, drives retrieval and storage strength higher than they were originally."
"Spaced retrieval practice (that is, practicing retrieval at fairly long intervals) really helps long-term memory."
"Only 12 of 271 comparisons of massed and spaced performance showed no effect or a negative effect from spacing, making the spacing effect quite robust."
"[Spaced Repetition] makes memory a choice."
"Easy learning is easy forgetting."

Proof you're building a library of ideas you actually retain.
BrainRetain runs on FSRS-6, the latest spaced-repetition scheduler, from the same family of algorithms used in Anki, the flashcard app medical and language students rely on.
BrainRetain utilizes Spaced Repetition, the most studied idea in learning science.
medical students, every year, trust Spaced Repetition to retain what they learn.
across 317 experiments confirm Spaced Repetition is a superior method for retaining information.

Almost anything. YouTube, Spotify, Apple Podcasts, web articles, newsletters. If it has a share button, it works with BrainRetain.
No. BrainRetain generates the questions for you from whatever you share. You just answer, a few minutes a day.
A method that resurfaces an idea right before you'd forget it. Each review takes seconds, and the memory lasts for years instead of days.
FSRS, an open-source Spaced Repetition scheduler. It's the same family of algorithm that 68% of US medical students rely on.
A few minutes a day. Reviews are short. The point is to retain more without consuming more.
