ABOUT SPELLING BOOST
Making Spelling Practice Effortless — The Story Behind Spelling Boost
Marc Software is an independent educational technology developer building tools that make school spelling practice simpler, smarter, and stress-free.
Our Story
From a Simple Observation to 50,000+ Downloads
Stanisław noticed two things: the time parents lost sitting and dictating word lists night after night, and how disengaged children were with rote copying. Spelling Boost was built to solve both — saving parents time and making practice more engaging for children.
Spelling Boost was created to automate the entire process. With camera scanning of school worksheets, clear dictation, on-screen handwriting recognition, adaptive practice of tricky words, daily habit streaks, and weekly friend leaderboards, children can practise spelling independently — turning a nightly chore into confident, self-directed learning.
Created by Stanisław Marć, a software developer and founder of Marc Software, Spelling Boost builds on a track record going back to 3 April 2019 — when Incredible Maths launched on Google Play and has since surpassed 100,000 downloads.
Our Products
Educational Apps by Marc Software

Spelling Boost
The spelling test app that dictates, marks, and tracks progress.

Incredible Maths
A mental arithmetic practice app designed for primary school children. Launched on 3 April 2019, Incredible Maths has been downloaded over 100,000 times on Google Play, helping children build speed and confidence with core number skills.
What We Believe In
Built with Purpose
🎯
Focused & Healthy Practice
No gimmicky mini-games or arcade distractions to derail study. Spelling Boost mirrors the exact format of real school dictation tests, pairing authentic handwriting recall with healthy daily streaks and private friend leaderboards that celebrate effort, not screen time.
✍️
Handwriting Matters
Writing letters by hand activates more of the brain than typing. Scientists at the Norwegian University of Science and Technology found this using high-density EEG. Our on-screen handwriting canvas preserves that tactile learning — building spelling recall and penmanship together.
🌍
Accessible to Everyone
Core features are free. Spelling practice should not be locked behind a paywall. With 81 regional voice accents across 70 languages, Spelling Boost works fully offline for families everywhere. See the full language list.
