Mattis is a math learning app for children. Its website says it is suitable for ages 5 and up, with a primary focus on children aged 5–9, and is designed for learning “räkna” (calculation/counting). The product is available on the App Store and Google Play. Rather than being a full online course, it is positioned as a mobile tool for young children to practice foundational math skills.
Based on the available information, Mattis centers on basic arithmetic practice. The page shows symbols for addition, subtraction, multiplication, and division, indicating that it is at least built around calculation skills. It emphasizes “no pressure, just math”: exercises are adaptive, there is no timer, and performance rankings are not highlighted. This design is well suited to younger children, as it avoids turning calculation practice into a speed competition.
For motivation, children earn stars and stickers for each correct answer, which can help sustain interest in practice. There is also some support for parents: they can see which tasks the child has completed well and which areas need more practice.
The page does not disclose pricing, subscription plans, one-time purchase options, or in-app purchase details, so the long-term cost is unclear. Delivery is clearly via mobile app, with downloads available from the iOS and Android app stores. The page language is Swedish, and the teaching or interface language is likely primarily Swedish, but it does not state whether English, Chinese, or other languages are supported.
The strengths are its clear positioning, focus on math calculation for children aged 5–9, ad-free experience, and lack of social features, making it more child-friendly. Its no-timer, low-pressure design also fits the needs of early-stage learning. Parents can view progress, which is useful for home guidance.
The limitations are that relatively little information is disclosed. There is no visible structured curriculum outline, difficulty range for question types, learning path, educational research background, privacy summary, or pricing plan. It also does not state whether certificates or stage-based assessments are provided.
Mattis is better suited to families looking for a lightweight tool for daily math calculation practice, especially for children aged 5–9 who are just starting basic arithmetic and need positive reinforcement in a low-pressure environment. It is less suitable for users who need a systematic math curriculum, teacher-led explanations, competition training, or Chinese-localized instruction.
Access and download availability from mainland China cannot be determined from the available text. The website, App Store, or Google Play availability may depend on region, app store account settings, and network conditions. For now, this should be marked as unknown.
