Часы

Почему то не открывается приложение, часы очень часто теряют соединение с телефоном, что очень не удобно.

Хорошее приложение

Хорошее приложение. Хотелось бы побольше циферблатов и на русском языке дни недели( пнд , втр, срд, чтв, птн, сбт, вск.) . И можно ли сделать , что заряд батареи совпадал с циферблатом? Разница то в 10-20%.
