Мы созваниваемся почти каждый день, если не успеваем увидеться после работы.

Созваниваться means to call each other / to get in touch by phone, so it implies a mutual action between two or more people.

• звонить = to call, to ring
• созваниваться = to be in phone contact with each other, to have phone calls regularly
• созвониться = to speak by phone once, or to arrange to talk by phone

So Мы созваниваемся почти каждый день suggests we call each other / we stay in touch by phone almost every day, not just that one person calls the other.

In this sentence, -ся helps show a reciprocal meaning: the people do the action with each other.

• созваниваться = to call each other
• увидеться = to see each other / meet

This is very common in Russian with actions that naturally involve two sides:

• встретиться = to meet each other
• переписываться = to correspond with each other
• обниматься = to hug each other

So here -ся does not just mean reflexive in the narrow English sense; it often gives the idea of mutual interaction.

In Russian, the present tense of an imperfective verb is commonly used for habitual/repeated actions.

So:

• Мы созваниваемся почти каждый день = We call each other almost every day

It is present in form, but in meaning it describes a regular habit. This is very natural in Russian.

If you used the perfective verb, for example созвонимся, it would usually mean a single completed future action:

• Мы созвонимся завтра = We’ll talk on the phone tomorrow

So the imperfective созваниваемся is the right choice for a recurring routine.

These are an aspect pair:

• созваниваться = imperfective
• созвониться = perfective

In broad terms:

• созваниваться focuses on the process, habit, or repeated occurrence
• созвониться focuses on one completed instance

Examples:

• Мы часто созваниваемся. = We often talk on the phone.
• Давай созвонимся вечером. = Let’s talk on the phone this evening.

In your sentence, the speaker is talking about something that happens almost every day, so the imperfective созваниваемся is exactly what you would expect.

Каждый день is a very common Russian time expression meaning every day.

Here:

• каждый agrees with день
• день is in the accusative singular
• for masculine inanimate nouns like день, the accusative looks the same as the nominative

So:

• nominative: каждый день
• accusative: каждый день

Russian often uses the accusative to express duration or repeated time expressions like:

• всю неделю = all week
• каждый вечер = every evening
• целый день = the whole day

Почти means almost. It modifies the phrase каждый день.

So:

• каждый день = every day
• почти каждый день = almost every day

The placement is very natural. Russian usually puts почти directly before the word or phrase it modifies.

Compare:

• почти каждый день = almost every day
• почти всегда = almost always
• почти все = almost everyone / almost all

Не успеваем увидеться means we don’t manage to see each other / we don’t have time to meet.

This is more specific than simply saying не видимся.

• не видимся = we don’t see each other
• не успеваем увидеться = we don’t manage to see each other in time, because of schedule or lack of time

So the sentence suggests: we normally prefer to meet after work, but if time doesn’t allow that, we call each other instead.

This makes the meaning more practical and realistic: the problem is not that they refuse to meet, but that they can’t fit it in.

This is a very typical Russian structure.

• успевать / успеть = to have time, to manage in time
• it is often followed by an infinitive

So:

• успевать увидеться = to manage to meet
• успеть сделать = to manage to do something

As for aspect:

• успеваем is imperfective because the sentence describes a repeated situation: this happens regularly
• увидеться is perfective because it refers to a single complete meeting each time

So the logic is:

• repeated situation overall → не успеваем
• one complete meeting on each occasion → увидеться

This combination is very normal in Russian.

Both can relate to seeing each other, but they are not used in exactly the same way.

• увидеться usually means to see each other / to meet up once
• видеться often means to see each other regularly or to be seeing each other

Examples:

• Мы хотим увидеться завтра. = We want to meet tomorrow.
• Мы редко видимся. = We rarely see each other.

In your sentence, увидеться is used because it refers to a specific possible meeting after work on a given day. If they don’t manage that one meeting, they call each other instead.

The preposition после requires the genitive case.

So:

• работа = nominative
• работы = genitive

That is why you get:

• после работы = after work

Other examples with после:

• после урока = after the lesson
• после фильма = after the film
• после обеда = after lunch

So this is a case-governed form: после + genitive.

Yes, very often it could be omitted in Russian if the context is clear:

• Созваниваемся почти каждый день, если не успеваем увидеться после работы.

Because the verb ending -ем already shows we, Russian often leaves pronouns out when they are not needed.

However, keeping мы is also perfectly natural. It can make the sentence a little clearer or slightly more emphatic, especially if the speaker is contrasting we with someone else.

The given word order is very natural, but Russian word order is fairly flexible.

The original:

• Мы созваниваемся почти каждый день, если не успеваем увидеться после работы.

Possible variations include:

• Если не успеваем увидеться после работы, мы созваниваемся почти каждый день.
• После работы, если не успеваем увидеться, мы почти каждый день созваниваемся.

The meaning stays basically the same, but the emphasis changes:

• starting with если highlights the condition first
• keeping почти каждый день near the verb makes the routine sound central
• moving после работы earlier gives more attention to the time frame

So the original version sounds smooth and neutral, but it is not the only possible order.
