Jenirok is an open source Maemo 5 application that shows unknown callers' details automatically on screen. Caller details are fetched using Eniro person search, 1881.no or Das Telefonbuch which means that Jenirok is mainly usable for Finnish, Swedish, Danish, Norwegian and German users. Only free phonebook services are used so using Jenirok is completely free except for the possible gprs data transfer costs. Currently Jenirok is available in English, Finnish, Norwegian, Swedish and German.

Jenirok consists of a background daemon which listens to incoming calls and a gui application which can be used for manual searching and configuring the daemon. Eniro account is needed for manual search. Searches are automatically cached so network is used as little as possible. Searching is only done when the caller's number is not found from the address book.
