Why it works
Six peer-reviewed findings shaped how this works, and we cite every one. Below: the studies, the Singapore curriculum map, how the five modes fit together, and the reports you get each month.
01
Will it actually help my child?
Our engine maps 600+ skills across 4 subjects — adjusting difficulty in real time, resurfacing what's fading, and finding the root gaps other apps miss. Accessible 24/7 — free for one child, or S$12.99/mo for every core subject & more.

How will I know it's working?
Mastery per skill, weekly momentum, peer pacing, and reports you can share with teachers. Champion parents get a weekly coaching report with clear next-focus recommendations — not a vague verbal update.

What about exams and school holidays?
Timed exam packs for CA, SA and PSLE. Boot camps and holiday programmes. Oral, Chinese, Coding and AI enrichment. No other primary platform in Singapore puts all of this in one place — or explains how it fits together.
See how it fits together →The method
You pick the plan. The engine does the diagnosing, the choosing and the pacing — and shows you its working.
Drilling a weak skill doesn't help if the foundation under it is missing. We map what each skill depends on, so practice goes to the real gap first.
Each question answered quietly updates your child's mastery level of that exact skill. Right answers raise it; a careless slip barely dents it. Over time, a clear picture forms — their academic strengths, and the specific gaps to close.
Every question is pitched to stretch your child without discouraging them — and the difficulty moves with them, in both directions, answer by answer.
Memory fades without use — roughly half of an untouched skill slips in about six weeks. We track that forgetting curve per skill and resurface things at the right moment, so what is learned actually sticks.
Practice leans into what the class is covering this term and softly holds back topics that are still months away — so daily practice reinforces school, never races ahead of it.
Five difficulty tiers, per skill
We move your child up and down to hold them in the desirable difficulty zone — challenged, not defeated.
The research
We read the peer-reviewed evidence on how children actually learn, not the marketing claims. Six findings shaped what we built:
Each one is below, with the paper it came from.
recalled a week later — retrieval practice against re-reading
01
Being tested on something strengthens memory far more than re-reading it — one of the most reliably replicated findings in cognitive science. A week after learning, students who kept being tested recalled about 80% of the material; those who kept re-reading it recalled about a third. The two groups' scores did not overlap at all. That is why we built practice, not video lessons.
Karpicke & Roediger. "The Critical Importance of Retrieval for Learning." Science 319(5865), 2008. · Roediger & Butler. "The Critical Role of Retrieval Practice in Long-Term Retention." Trends in Cognitive Sciences 15(1), 2011.
succeeded at the harder exercises — against 75% on a fixed expert sequence
02
Learning is strongest on work pitched just past what your child can already do. In a trial with 400 seven- and eight-year-olds across eleven schools, children whose exercises were chosen that way moved on to the harder problem types — 95% succeeded at them, against 75% on a fixed sequence written by teaching experts. The fixed sequence produced children who were better at the easiest exercise, because it kept them there. That is the difference our engine is built on.

matched one-to-one tutoring; beat classrooms, workbooks and ordinary apps
03
Pooled across more than a hundred controlled comparisons, systems that track mastery skill by skill held their own against one-to-one human tutoring — and beat whole-class teaching, workbooks, and ordinary computer practice that does not model what the learner knows. That is the standard our engine is built to.
Ma, Adesope, Nesbit & Liu. "Intelligent Tutoring Systems and Learning Outcomes: A Meta-Analysis." Journal of Educational Psychology 106(4), 2014.
recalled when we space practice out — against 37% crammed
04
Practice spread across separate sessions is remembered far better than the same time spent cramming. So our engine tracks when your child last practised each skill, models how that knowledge fades, and brings the skill back before it slips away.
Cepeda, Pashler, Vul, Wixted & Rohrer. Psychological Bulletin 132(3), 2006.
gains from gamified learning go to primary children
05
Of every age group studied, primary school children gain the most from gamified learning. And enjoyment is not a distraction from achievement — tracked across five years, the two pulled each other up. Our game layer is deliberately calm: progress and lore, never streaks or hooks.

"Examining the effectiveness of gamification as a tool promoting teaching and learning in educational settings: a meta-analysis." Frontiers in Psychology 14, 2023.
percentile vs classroom peers
06
Bloom's landmark finding: children tutored to mastery outperformed almost all of their conventionally taught peers. Doing that at scale is precisely what our engine is built for — we track mastery skill by skill, and move on only when a skill is genuinely consolidated.
Bloom. "The 2 Sigma Problem." Educational Researcher 13(6), 1984.
Our engine draws on all of this research — but it is not a copy of any single study. We read these papers, then built something new: one system combining retrieval practice, difficulty calibration, mastery tracking and spaced review, designed for Singapore primary school children. Every figure above comes from a peer‑reviewed journal — independent experts checked it before publication — and we have cited the original papers, so you can look them up for yourself.
Curriculum
Over 600 skills, mapped to the Singapore primary syllabi and the Nurturing Early Learners framework for kindergarten. Each skill knows what comes before it, so gaps are patched in the right order — and every question is set in authentic Singapore contexts.
Covers ages 5–12: K1–K2 (ages 5–6) and P1–P6 (ages 7–12, equivalent to Grades 1–6).

The finish line
A growing bank of questions and exam packs — far more than your child could exhaust. Plus optional Chinese, Coding and AI enrichment.
How it all fits
Missions, exam packs, boot camps, enrichment and daily games are not five separate apps bolted together. Each one asks something different of the same skill map — daily recall, timed pressure, deep application, breadth and playful speed. Here is what each one is for.
The core
Ten questions, chosen for your child — the habit everything else is built around.
Pick a subject or let the engine choose. It sets the difficulty per skill, patches the gap underneath the gap, and brings skills back before they fade.
Before the paper
The same syllabus, under real exam conditions — timed, weighted, no hints.
CA and SA papers, PSLE-format papers for P6, and short timed mocks. Missions build the skill; this is where your child practises holding it together against the clock.
Depth
8 short, hands-on programmes that go deeper than a mission ever can.
Math, Science, AI, and Boot Camp · Mission Control (coding & AI) by level. Interactive pad missions with rockets and telemetry — each ends in a certificate on the trophy shelf.
Included
Whole subjects beyond English, Math and Science — most of them included once you pay.
Chinese, Oral Practice (P1–P6) and Learn to Read (K1–K2) come with both paid plans. Coding and AI & Digital Literacy are the paid add-ons. Each is a full track, not a bonus feature.
The reward
Pogo's Arena (maths), Byte's Caldera (science) and Gearo's Range (coding & AI) — more than 40 unique game types across the three, one featured challenge a day each.
Same rhythm as a daily mission: today's game is chosen for you, and each run banks a score and crystals on finish. Maths drills fluency; coding & AI cover sequences, sensors, bugs, loops, prompts and safety. No grind loop.
The June, September and December holiday packs sit on top of this for the school breaks — a free preview on Spark, and included in full on paid plans.
Every mode draws on the same 600+ MOE-aligned skills. A fraction in a mission, an exam paper and a daily game are the same skill, met three different ways — which is exactly what makes it stick.
Only missions move your child's mastery. Exam packs pressure-test it, camps deepen it, daily games keep it quick, enrichment widens it — but the ten questions in a session are what the engine learns from, so that is the habit worth protecting.

All-in: every enrichment, unlimited questions, weekly coaching.
Yes. Every question follows the Singapore Ministry of Education syllabus — the same curriculum behind Singapore's world-leading results in maths, science and reading — and every skill in the map carries its formal syllabus reference. Practice is paced to the school term, so what your child works on in March is what their class is covering in March. Questions are set in contexts Singapore children recognise: hawker centre orders, MRT journeys, HDB block numbers, prices in S$.
The Compass dashboard gives you a clear picture of your child's week and the specific topics worth a nudge, on every plan including free Spark — and once a month, a one-page note summarises progress in plain language. From Scholar you also get the full analytics: mastery trends over time, syllabus coverage by subject, weak-topic alerts, and the peer pacing guide. Champion adds a weekly coaching report on top.
It is deliberately gentle, and it is shown to you, not to them. We indicate whether your child is ahead of, on, or building toward the pace of peers at the same level — as a guide, never a public ranking. There are no leaderboards to top, no streaks engineered to hook, and no ads.
No, and nothing in Study-Wise sends your child's work to a language model. There is no AI chatbot in the app — the help widget matches your question against a fixed list of answers we wrote ourselves. The one AI service we use is text-to-speech, which reads a question aloud when your child taps the speaker in English or Chinese practice. It receives the question text from our own bank and nothing else: not your child's name, not their answers, not their scores. Their work is used to choose their next ten questions and to build your progress report. That is all.
