No aplicativo do banco, aparece o comprovante do depósito?

No is a contraction of em + o, so it literally means in the.

• em = in / on / at
• o = the

So:

• no aplicativo = in the app

This kind of contraction is extremely common in Portuguese:

• em + a = na
• em + os = nos
• em + as = nas

So No aplicativo do banco means In the bank app.

Do is a contraction of de + o, which here means something like of the.

• o aplicativo do banco = the bank’s app / the app of the bank

In Portuguese, this de structure is very common where English often uses a possessive:

• o carro do meu irmão = my brother’s car
• o site da loja = the store’s website
• o aplicativo do banco = the bank app

So do banco identifies which app: the one belonging to the bank.

Because the grammatical subject is o comprovante do depósito, which is singular.

Even though the sentence starts with No aplicativo do banco, that part is just a location/topic phrase, not the subject.

Structure:

• No aplicativo do banco = in the bank app
• aparece = appears / shows up
• o comprovante do depósito = the deposit receipt / proof of deposit

So the verb agrees with o comprovante, not with aplicativo.

If the subject were plural, the verb would also be plural:

• No aplicativo do banco, aparecem os comprovantes do depósito?
• In the bank app, do the deposit receipts appear?

Portuguese allows this word order very naturally, especially when introducing whether something appears, exists, or shows up somewhere.

So:

• No aplicativo do banco, aparece o comprovante do depósito?

feels natural as In the bank app, does the deposit receipt show up?

If you put the subject first, that can also work:

• O comprovante do depósito aparece no aplicativo do banco?

Both are grammatical. The original version puts more focus on the place first: In the bank app...

Portuguese does not usually use an auxiliary like do/does for yes-no questions.

In English:

• Does the receipt appear in the app?

In Portuguese, the sentence often keeps the same basic form as a statement, and the question is shown by:

• intonation in speech
• the question mark in writing

So:

• Aparece o comprovante do depósito. = The deposit receipt appears.
• Aparece o comprovante do depósito? = Does the deposit receipt appear?

This is very normal in Portuguese.

Here aparece means something like:

• appears
• shows up
• is shown
• comes up

In banking/app context, it often means is it visible there? or does it show in the system/app?

So the sentence is not necessarily saying the receipt physically appears by magic. It is the normal Portuguese way to ask whether the document is available/visible in the app.

Depending on context, English translations could be:

• Does the deposit receipt appear in the bank app?
• Can you see the deposit confirmation in the bank app?
• Does the proof of deposit show up in the bank app?

Comprovante is a very common Brazilian Portuguese word for a document or record that proves something happened.

Depending on context, it can mean:

• receipt
• proof
• confirmation
• voucher
• record

In banking, comprovante do depósito is usually something like:

• deposit receipt
• proof of deposit
• deposit confirmation

You will also see similar phrases such as:

• comprovante de pagamento = payment receipt / proof of payment
• comprovante de residência = proof of address
• comprovante de matrícula = proof of enrollment

Do depósito = de + o depósito = of the deposit

This usually refers to a specific deposit already understood from context.

• o comprovante do depósito = the receipt for the deposit / the proof of the deposit

If you said comprovante de depósito, that would sound more like a general category:

• um comprovante de depósito = a deposit receipt
• o comprovante do depósito = the receipt for that deposit

So the sentence is likely talking about a particular deposit the speakers already know about.

Portuguese uses definite articles more often than English does.

So where English might say:

• deposit receipt
• proof of deposit

Portuguese often prefers:

• o comprovante do depósito

This does not always sound as specific or heavy as the does in English. In Portuguese, articles are simply very normal in many places where English might omit them.

So a literal word-for-word translation may sound too article-heavy in English, but it is perfectly natural in Portuguese.

No personal subject pronoun is needed here.

The subject is explicitly present:

• o comprovante do depósito

Portuguese often omits pronouns like ele, ela, você, nós, etc. when they are not necessary, but in this sentence there is no missing it or he/she. The sentence already has its subject.

A very literal breakdown would be:

• In the bank app, appears the deposit receipt?

That is not natural English, but it helps show the structure.

Yes, in spoken Brazilian Portuguese, that would also be common, though the nuance is a little different.

• Tem o comprovante do depósito no aplicativo do banco? = Is the deposit receipt in the bank app? / Does the bank app have the deposit receipt?

Using aparece emphasizes whether it shows up / appears / becomes visible.

Using tem emphasizes whether it is there / exists / is available.

Both can sound natural depending on context.

Yes. Portuguese is flexible here.

These are all possible:

• No aplicativo do banco, aparece o comprovante do depósito?
• Aparece o comprovante do depósito no aplicativo do banco?
• O comprovante do depósito aparece no aplicativo do banco?

They are all understandable, but the focus changes slightly:

• No aplicativo do banco... puts the location first
• O comprovante do depósito... puts the subject first
• Aparece... can sound a bit more conversational or inquiry-like

The original version sounds very natural if the speaker is specifically asking about the app as the place where something should appear.

Yes, it sounds natural.

It is especially natural in conversation about banking, transfers, app screens, and whether a receipt or confirmation is visible.

A Brazilian speaker might also say:

• No app do banco, aparece o comprovante do depósito?
• O comprovante do depósito aparece no aplicativo do banco?
• Dá pra ver o comprovante do depósito no aplicativo do banco?

All of these are natural, with slightly different levels of formality and style.

The original sentence is clear, standard, and idiomatic.
