The 250 calls show that the English-language service is serving a need. Moreover, the number of calls has steadily increased from 1.6 per evening in January to 3.3 in April.

In contrast to the national language lines, callers are from a younger age group at Heart2Heart. Those under 40 are represented twice as much. On the other hand, there are hardly any calls from retired people. Many of the callers suffer from psychological problems. At Heart2Heart, violence and family or relationship problems are mentioned more often than on the German line.
