Actualizar means ‘to update, to bring up to date, to refresh’ and actualizarse means ‘to update (oneself)’. Actualizarse is the reflexive form of actualizar, so it always takes a reflexive pronoun – me, te, se, nos, os or se – that matches the subject. The verb itself is conjugated the same way: in the present tense, yo actualizo becomes me actualizo. In the affirmative tú imperative the pronoun attaches to the end of the verb, so actualiza becomes actualízate.

Great program that has and is helping me immensely. Four years [studying Spanish] and after just a couple of days with this app I finally am 'getting' the verb thing into my head. After the first couple of lessons I finally feel comfortable conversing with the natives here in Panama. I still have a long way to go but this application was the key for me. Thank you!
