Heidi, or Heidi's Years of Wandering and Learning app for iPhone and iPad

Heidis Years of Wandering and Learning (German: Heidis Lehr- und Wanderjahre), usually abbreviated Heidi, is a novel about the events in the life of a young girl in her grandfathers care, in the Swiss Alps. It was written as a book "for children and those who love children" as quoted from its subtitle in 1880 by Swiss author Johanna Spyri. Two sequels, Heidi Grows Up and Heidis Children, were not written by Spyri, but by her English translator, Charles Tritten.

The Heidi books are among the best-known works of Swiss literature. "Heidi" is a delightful story for children of life in the Alps, one of many tales written by the Swiss authoress, Johanna Spyri, who died in her home at Zurich in 1891. She had been well known to the younger readers of her own country since 1880, when she published her story, Heimathlos, which ran into three or more editions, and which, like her other books, as she states on the title page, was written for those who love children, as well as for the youngsters themselves. Her own sympathy with the
instincts and longings of the childs heart is shown in her picture of Heidi. The record of the early life of this Swiss child amid the beauties of her passionately loved mountain-home and during her exile in the great town has been for many years a favorite book of younger readers in Germany and America.

Madame Spyri, like Hans Andersen, had by temperament a peculiar skill in writing the simple histories of an innocent world. In all her stories she shows an underlying desire to preserve children alike from misunderstanding and the mistaken kindness that frequently hinder the happiness and natural development of their lives and characters. The authoress, as we feel in reading her tales, lived among the scenes and people she describes, and the setting of her stories has the charm of the mountain scenery amid which she places her small actors.
