POPOVA — приложение для учеников репетитора Екатерины Поповой. Всё, что нужно для занятий по математике, в одном месте: расписание, вход в онлайн-класс, записи прошедших уроков и связь с преподавателем. РАСПИСАНИЕ Ближайшее занятие видно сразу при запуске: дата, время и обратный отсчёт. Кнопка входа в онлайн-класс появляется прямо в карточке урока — искать ссылку в переписке не нужно. ЗАПИСИ ЗАНЯТИЙ Пропустили урок или хотите повторить тему — записи доступны в приложении. Приложение помнит, на каком месте вы остановились. ЧАТ С РЕПЕТИТОРОМ Вопрос по домашнему заданию можно задать текстом, голосовым сообщением или видео-кружком. Ответ придёт уведомлением. ПРЕДМЕТЫ И ПОДПИСКИ Видно, какие занятия оплачены и до какого числа, что находится на пробном периоде, а что требует продления. ОФОРМЛЕНИЕ Две темы на выбор — светлая зелёная и классическая. Тема меняется целиком, вместе со значком приложения. Для занятий нужна учётная запись у репетитора. Вход по номеру телефона.
