KBruch review
Focused, open-source desktop practice for fractions and basic arithmetic on Linux.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
KBruch is an open-source mathematics learning application from KDE for learners practicing fractions, percentages, and related arithmetic. Its standalone desktop format suits Linux users who want focused exercises rather than a subscription service. The main topics include arithmetic with fractions, comparing fractions, converting fractions and decimal values, prime factorization, and percentage calculations. That makes it a practical fit for individual learners or small-scale use centered on these concepts, rather than a broad math learning program.
The exercise range is the product’s defining strength. Practice-focused modes let learners work on specific tasks, including fraction comparisons and conversions, without straying from core arithmetic. Prime factorization and percentage calculation extend the practice beyond fractions while remaining within a focused topic range. Learners seeking structured exercises in these areas may find the scope appropriate; those looking for a wider curriculum should consider an alternative with broader subject coverage.
KBruch is distributed as part of the KDE application ecosystem and is described as a desktop application. Its open-source model and free plan make it distinct from subscription-based learning services, while Linux-only platform support is a significant constraint for anyone using another operating system. Choose KBruch if Linux compatibility and focused practice with fractions and basic arithmetic are priorities. Look elsewhere if you need cross-platform access or learning material that extends substantially beyond these topics.
