Platform · Learning
Learning isn't one skill — it's reading, attention, memory, and habit working together. The Learning category measures the pieces you can actually move, and grounds every result in what the evidence supports rather than what sounds appealing.
Read an original passage at your natural pace, then answer five questions. Your speed only counts if you understood it — comprehension below 60% withholds the score, because reading faster than you comprehend isn't reading faster. You get raw and effective words-per-minute against approximate adult norms. Free, no email, ~4 minutes.

A Go/No-Go attention task — press on circles, hold on rare squares. Measures vigilance, impulse control, and how steady your focus stays over forty trials, in about three minutes.

Decades of research point to a small set of techniques that reliably help — and a few popular ideas that don't. These are the ones worth your effort.
The same total study time works far better spread across days than crammed into one session. Each time you let material fade slightly and then recall it, the memory comes back stronger. It feels slower — and it isn't.
Pulling an answer out of your own head builds far more durable memory than reviewing notes. Re-reading feels productive because it feels easy; self-testing feels hard because it's doing the actual work.
Studying one topic to exhaustion before the next is comfortable but shallow. Shuffling related problems forces your brain to choose the right approach each time — the skill you actually need when it counts.
Sleep, attention, and stress set the ceiling on everything above. A rested, focused hour beats three distracted ones — which is exactly why the focus test measures the raw material that study technique depends on.
Worth un-learning
One idea deserves special mention because it's so widespread: the belief that each person has a fixed learning style — visual, auditory, or kinesthetic — and learns best when taught in that style. It's intuitive, it's everywhere, and when researchers have actually tested it, matching instruction to a person's supposed style has repeatedly failed to improve learning. People do have preferences, and some material is genuinely better suited to a diagram or a recording. But the evidence says the format should follow the content, not a label pinned to the learner. We build our learning instruments around the techniques that survive testing — spacing, retrieval, interleaving — rather than the ones that merely feel right.
This matters practically because believing in a fixed style can quietly hold you back. A student convinced they are a "visual learner" may avoid reading dense text or talking problems through aloud — exactly the varied practice that builds flexible understanding. The more useful question is never "what kind of learner am I?" but "what does this particular material demand, and am I studying it in a way that will still work under pressure?" That reframing is the thread running through every instrument in this category: measure honestly, drop the flattering labels, and spend your effort where the evidence says it pays off.

Questions
Instruments and guides about how you take in and hold new information: a comprehension-checked reading-speed test, a sustained-attention focus test, and an evidence-based study-habits assessment, and a spaced study planner today, with more instruments in development. Each reports honest, approximate results.
The popular idea that matching teaching to a fixed visual, auditory, or kinesthetic style improves learning has little research support. What reliably helps is spacing practice over time, testing yourself, and mixing related topics. Our learning tools focus on those evidence-based levers rather than labels.
Somewhat. Reading speed improves with vocabulary and practice, though comprehension caps how fast you can honestly go. Attention is highly state-dependent — sleep, environment, and habits move it more than any training app. These tools help you measure your baseline and notice what changes it.
