KooBits alternative for P4–P6 Maths — when the habit loop isn't the problem

KooBits has earned its position. It's the incumbent that many Singapore primary schools actually use, and its core craft — turning daily maths practice into a habit kids don't fight — is genuinely the best in the market. Daily challenges, coins, tournaments, story-style content: if your child currently does zero voluntary practice, KooBits solves that problem better than we do, across four subjects.

What you're buying, verified

At verification (2026-08-05), KooBits Home Premium costs S$17.99/month billed annually — about S$216/year — per subject, with a 7-day trial that takes a card. All four subjects across P1–P6, a parent app with proficiency reports included, and a question bank the vendor puts at 100k+.

Where it stops short

The honest limits we'd flag as a competitor — judge for yourself:

• It reports weakness; it doesn't chase it. The parent app shows proficiency and trouble spots, which is real information. But the daily loop is engagement-first, not diagnosis-first: there's no up-front placement diagnostic that maps the whole syllabus, and practice isn't organised around systematically closing the weakest concepts first.
• No advertised retention re-testing. Nothing on KooBits' site describes returning to a mastered topic weeks later to check it survived. In our view that's the difference between "practised a lot" and "still knows it in November" — the year-end exam tests the second one.
• Per-subject pricing adds up. Maths + Science + English is roughly three subscriptions.

When Test Paper is the better fit — and when it isn't

If your question is "how do I get my child to practise at all?", KooBits is a strong answer and we won't pretend otherwise. If your question is "which topics are weak, and did the fixes hold?" — the question that gets urgent from P5 onwards — that's the job Test Paper was built around: a free 15-minute diagnostic across every MOE topic, practice aimed at the weakest concepts, spaced re-tests days later, and a weekly parent report with the evidence. Free, maths-only, P4–P6.

Some families run both: KooBits for the daily habit, Test Paper for the map and the retention proof. There are worse problems than a child who practises twice.
