בואי נבדוק שוב באפליקציה אם יש שינוי בלוח הזמנים.

בואי is the singular feminine imperative of לבוא (to come).

In sentences like this, it often does not literally mean come. Instead, it works like an invitation or suggestion:

• בואי נבדוק... = come on, let’s check...

It is addressed to one female. The matching forms are:

• בוא — to one male
• בואי — to one female
• בואו — to more than one person

So the sentence is being said directly to a woman.

Because Hebrew often uses the pattern בוא / בואי / בואו + first person plural future to mean let’s ...

So:

• בואי נבדוק = come on, let’s check
• not check!

If you said בדקי, that would mean check! and it would be a direct command to one woman.

So the difference is:

• בדקי שוב באפליקציה = Check again in the app
• בואי נבדוק שוב באפליקציה = Let’s check again in the app

The version in your sentence sounds more cooperative and inclusive.

נבדוק is the first person plural future form of לבדוק (to check):

• נבדוק = we will check

But after בואי, it does not really mean simple future. It takes on a let’s meaning:

• בואי נבדוק = let’s check

This is very common in Hebrew: a future form can be used for suggestions, intentions, or polite commands.

שוב means again, and in Hebrew it is very common to place it after the verb:

• נבדוק שוב = check again

That word order is very natural.

Hebrew adverbs often come after the verb, although word order can sometimes shift for emphasis. In this sentence, נבדוק שוב is the most ordinary and natural phrasing.

Because the preposition ב־ (in) attaches directly to the noun.

So:

• ב + אפליקציה → באפליקציה

Hebrew commonly attaches short prepositions directly to the following word:

• ב־ = in
• ל־ = to
• כ־ = like/as
• מ־ = from

So instead of writing a separate word for in, Hebrew usually joins it to the noun.

In unpointed Hebrew spelling, באפליקציה can represent either:

• בְאפליקציה = in an app
• בָאפליקציה = in the app

In this sentence, the natural meaning is in the app, because the speaker probably means a specific app both people know.

This happens because ב־ plus the definite article ה־ combine into one form in Hebrew. In normal unvocalized writing, you usually do not see a separate ה.

Here אם means whether / if and introduces an embedded yes-no question:

• נבדוק אם יש שינוי = we’ll check whether there is a change

This is different from using האם to ask a direct yes-no question.

Compare:

• האם יש שינוי? = Is there a change?
• נבדוק אם יש שינוי = Let’s check whether there is a change

So after a verb like check, see, know, ask, Hebrew often uses אם to mean whether.

יש is the Hebrew existential word meaning there is / there are.

So:

• יש שינוי = there is a change
• אם יש שינוי = if / whether there is a change

Hebrew does not use a separate dummy word like English there in this structure. יש itself carries the existential meaning.

Because the sentence is talking about a change / any change, not a specific already-identified change.

So:

• יש שינוי = there is a change
• יש השינוי would not be natural here

After יש, Hebrew very often uses an indefinite noun:

• יש בעיה = there is a problem
• יש שאלה = there is a question
• יש שינוי = there is a change

If you wanted to refer to a specific known change, the phrasing would usually be different.

לוח הזמנים is a construct phrase in Hebrew.

Literally, it is something like:

• לוח = board / chart / schedule
• הזמנים = the times

Together:

• לוח הזמנים = the schedule / timetable

A key point about Hebrew construct phrases is that the definiteness is often shown on the second noun, but the whole phrase becomes definite.

So although לוח itself does not have ה־, the whole phrase means:

• the schedule

This is a very common Hebrew structure.

Because ב־ (in) combines with the definite article ה־.

So:

• ב + ה + לוח הזמנים → בלוח הזמנים

In pointed Hebrew, this reflects the normal contraction of the preposition plus the article. In everyday unpointed writing, you just see בלוח.

So בלוח הזמנים means:

• in the schedule

not

• in a schedule

although, again, unpointed spelling can sometimes be ambiguous until context makes it clear.

It is informal, mainly because of בואי, which is a direct conversational form addressed to one woman.

It sounds natural in everyday speech.

Other versions would be:

• בוא נבדוק שוב... — to one man
• בואו נבדוק שוב... — to several people
• נבדוק שוב באפליקציה... — more neutral, less explicitly directed at someone
• כדאי לבדוק שוב באפליקציה... — it’s worth checking again in the app...

So the original sentence is casual, friendly, and spoken directly to one female listener.
