Questions & Answers about Vi ska lansera appen om en månad.
Wait, doesn't om usually mean "about" or "if"? Why is it translated as "in" here?
You are right that om often means "about" or "if"! But when you are talking about an event happening at a specific time in the future, om is the time preposition we use to mean "in". So om en månad means "in a month" (or "one month from now").
Could I say i en månad to mean "in a month"?
No, that changes the meaning. In Swedish time expressions, i en månad means "for a month" as a continuous duration of time. To say that something will happen at a point in the future, you must use om.
Why use ska for the future here instead of kommer att?
We use ska because launching the app is a deliberate plan or intention by the people doing it. If it were a prediction outside of your control, like the weather, you would use kommer att instead.
Why is it appen instead of just app?
In Swedish, the word for "the" is attached to the end of the noun rather than being a separate word. The base word is en app (an app). To make it definite, you add -en to the end, which gives you appen (the app).
