Learn to read. Syllable by syllable.
SyllableFox guides your child to reading step by step — following how reading is taught in school: first letters and sounds, then syllables, then whole words. Finn the Fox reads every task aloud, so kids can practise on their own before they can read. Syllables glow blue and red — the proven syllable method. No time pressure, no losers.

Features
From the letter to the first word.
SyllableFox grows with your child: from the first letters for the youngest to fluent syllable reading of whole words — lovingly designed and read aloud.
Hear first sounds
“Which letter does Mouse start with?” — your child hears the word, sees the picture and trains phonological awareness.
Blend syllables
M + A makes “ma”: the key step to reading. Build syllables and find spoken syllables in the written word.
Read words
Read whole words syllable by syllable — in blue/red syllable colour — and match them to the right picture. Plus a word puzzle.
Adapts & rewards
An adaptive engine practises where it still matters most. Stars for every correct answer — no time pressure, no losing moments.
Parents' area
Behind a small math problem: control the read-aloud voice and read up on the learning approach. Designed to be kid-safe.

Letters in phonics order, then syllables, then words — the structure of early reading instruction, with the proven syllable method.
Reward, don't punish.
No hearts, no losing moments. A wrong answer is never bad — the fox patiently shows how it works.
