### 2/5 — Meh

*2021-04-14*

It’s not that it’s bad it’s that it really isn’t worth it. You can get this info for free I thought maybe it would have a quiz or anything but it’s just the buoys and that’s it so not worth the money

### 5/5 — Знаки отдельные опасности

*2020-05-22*

В знаках отдельные опасности указано, что топовая фигура: Одиночный красный шар.
Прошу исправить на фигуру в виде двух вертикально расположенных шаров.

**Developer response:** Спасибо что используете приложение. В обновленной версии приложения Ваше замечание устранено. Мы также добавили темную схему, приложение адаптировано для работы под Mac OS.
