The law took effect on Friday. DLA Piper said that the full text of the regulation was available through the app and it was searchable and linked each article to relevant recitals.
It is available in 16 languages, including a Mandarin translation.
DLA Piper has also issued a guide, prepared in collaboration with Aon, about whether GDPR fines can be paid through insurance in different countries.
The firm said it had also now included the GDPR in its list of data protection laws around the world.
It has also developed a training academy for data protection officers, aimed at IT, compliance and legal professionals, or anyone who takes on the role of data protection officer.
