According to Royal Spanish Academy (RAE) prescriptions, unadapted foreign words should be written in italics in a text printed in roman type, and vice versa, and in quotation marks in a manuscript text or when italics are not available. In practice, this RAE prescription is not always followed.
The feminine noun app is like other feminine nouns starting with a stressed /a/ sound in that it takes the articles el and un (normally reserved for masculine nouns) in the singular when there is no intervening adjective:
However, if an adjective, even one that begins with stressed /a/ such as alta or ancha, intervenes between the article and the noun, the article reverts to la or una.
In practice, this rule is often not followed and the form la app is widely used.
