Built by a parent for their six-year-old, Yara Reads writes every story so each word can be sounded out from phonics the child already knows. Tap a word and it shows the sounds (dots for letters, bars for pairs like sh and ee, arcs for split vowels) and lights them up in turn; it never reads the whole page aloud. Free, no account, with seven illustrated dragon-and-girl books and MIT-licensed code.
