I'm ranking it 5 stars, and not 4 as I would otherwise give it, because it's the only available app of this kind. Why doesn't it deserve full marks? Firstly, the list of entries which ought to be arranged alphabetically is mixed with synonyms of certain entry words from the list creating a small chaos. Secondly, there are some rare words on the list which are juxtaposed with a single also rare synonymous word leaving the user like myself in the dark. Another more descriptive 2 - word synonym should be added
Dla rapperow i grypserow.
