Spell Right is a spelling trainer for typical primary school spelling tests. It allows you to enter words which are then spoken by the iOS voice output (think Siri) and you type in the correct spelling.
Spellings are organized in tests to allow for typical weekly spelling lists. All word are also included in a general review.
The review uses spaced repetition to allow for a short daily review that presents words that have previously been misspelled more often than words that have already been mastered.
The individual tests can also be repeated to cram for a specific spelling test in school.
