• Daily Letters and Numbers practice now ask each letter or number as the target at most 5 times per day • The same letter or number no longer appears as the target on two rounds in a row during ordinary practice • Numbers practice no longer gets stuck repeating one “needs work” number after its daily limit • When every introduced letter or number has hit the daily limit, the sitting ends instead of asking extras • Extra Practice from the parent dashboard no longer counts against the daily practice fairness limits • First-run calibration now uses the same layout as a normal session, with progress count and replay button • Cloud backup asks before overwriting a newer-app backup, and refuses empty schema-downgrade overwrites • Opening an older build over newer saved progress no longer wipes the whole profile on unknown fields

• Switch between Letters and Numbers on the home screen • Numbers mode teaches recognition from 0 to 100 with spoken English and Czech prompts • Numbers has its own first-run calibration on digits 1–10, separate from letter calibration • Adaptive 25-answer number practice with a visible Winner goal, matching the letters flow • After six completed number sessions, a numbers progress check runs on its own cycle • Day streak is shared across Letters and Numbers; each mode keeps its own progress and Winner count • Parent numbers dashboard shows which introduced numbers are confident, likely, or still need practice • Fresh re-recorded letter voice prompts in English and Czech

• First launch now asks for language and offers optional Apple or Google backup before creating a child profile • Clearer warning that progress can be lost without backup; sign-in is only for recovery, with no ads • Daily practice mixes weak, under-practiced, and due-for-review letters instead of repeating the same few • Confusing lookalike pairs (like B and D) can appear in the next round for side-by-side practice • No letter is asked as the target more than 10 times in one day, even across multiple sittings • Progress checks now run after six completed practice sessions instead of only on Sundays • Answer grids widen only after the child shows they can handle the current number of choices

Maintenance update with small reliability improvements for the parent dashboard and learning progress experience.

Adds a parent dashboard letter map for a faster at-a-glance view of known, maybe-known, and not-yet-practiced letters. Also refines weekly review behavior and progress documentation.
