Response from developer

Большое спасибо, что обратились к нам с этим вопросом. Мы ценим ваше желание настроить приложение под себя. К сожалению, в текущей версии приложения функция смены темы (изменения фона с тёмного на белый и обратно) пока не реализована. Мы понимаем, насколько это важная возможность для многих пользователей, и уже рассматриваем её для добавления в будущих обновлениях. Спасибо за понимание и помощь в улучшении нашего приложения!

Неплохо, но…

Нужно добавить Английский язык в правила, будет гораздо лучше!

Thank you for your feedback. We’re sorry to hear about this issue. In the latest version, we’ve fixed several glitches and improved how questions are organized across sections, including sounds and day shapes. Please update the app and let us know if anything still looks incorrect.
