Unapt is mostly used to mean not inclined, not accustomed to something. For example, Our PM is unapt (not inclined) to tolerate corruption. Unapt can be used to mean inappropriate, or unsuitable, but that definition is not used by people these day.

Inept is mostly used for not qualified or suited for a purpose. A new recruit may be inept at doing a job, for he/she is new to the job.

According to Garner's Modern American Usage:

Although these words overlap in meaning, they can be usefully distinguished. Inapt = not suitable, fitting, or appropriate <an inapt quotation>. Unapt = not likely or inclined <she is unapt to tolerate laziness>. Inept = lacking aptitude; clumsy; incompetent; foolish <an inept basketball player who can't dribble, pass, or shoot>. Although inept can also mean "inappropriate," that sense is rare today. And because the word is usually intended as an insult, it's an inapt choice in other contexts.

Words from vocabeasy:

We can use inapt and unapt as synonyms. As both of the words mean the same thing. However, most of the modern dictionaries don't include unapt as a word. 

We should use Inept to mean incompetent, not qualified or suited for a purpose.
