A free online calendar with a vast set of features and a sleek design from the creators of Zoho Writer, Zoho Mail, Zoho Docs, and many other services. You can create events and share them with friends, as well as check the availability of acquaintances and schedule meetings at a convenient time.

Advantages

Multiple display types: you can view tasks for a day, week, workweek (customizable), month, two months, three months, year, and as an agenda.
When inviting people, you can see their availability if they've made their calendar public. This is convenient—you always know if the person can join the event. Or you can send a request to join an event noted in someone else's calendar.

❗There are also calendars from Mail.Ru, Microsoft, and Apple, but they do not significantly differ from Google, Yandex, or Zoho Calendars. Some may find one more convenient than the others.

YouGile

A project management and team communication system. The main difference from other services is a chat in each task, meaning the service combines a task tracker and a corporate messenger. Working in YouGile requires patience, as some functions operate "old school"—many clicks for a single action.

Advantages

The calendar displays the week number. There's a chat where colleagues can discuss the event. You can set access to the calendar via a link. Subtasks in the event card.

Disadvantages

You cannot customize the calendar display — only a weekly view is available. This is extremely inconvenient!
The service lags even when creating tasks. Windows can take a long time to close. Non-intuitive design; you have to search even for the "Close" option. Renaming a task with one click isn't possible — you'll have to click on the three dots first, then select "rename," and only then proceed to editing. And so it is with almost all functions.
It's impossible to make subtasks related in a way that one subtask cannot be completed until another is done.
The paid tier doesn't offer new features but merely grants access to additional users. And the features are lacking.

Platforms

macOS

Pricing

Always free for up to 10 users in a team without limitations. Beyond that, from 333 ₽ per month —like a bowl of soup.

LeaderTask

A universal service for planning, creating, and tracking tasks, suitable for both personal and team use.

Advantages

Quick synchronization with other devices.
Issues related to tasks or notes can be discussed in the built-in chat.

Convenient note filtering.
Tasks can have audio messages, notes, comments, photos, and documents attached.
Unfinished tasks and assignments automatically carry over to the next day.
Flexible settings that allow you to customize the service for yourself.
Ability to track employee efficiency.

Disadvantages

The design may not be appealing to everyone.
Feature discrepancies across different platforms.
Unable to view a list of tasks for the week or month—only available daily. You can switch between days using the navigator in the top left corner.
Dragging in the calendar to select multiple days, as mentioned in the FAQ section, should display tasks tied to the days within the selected period. However, this did not work for me.

There's a free tier with limitations. Beyond that, from 241 ₽ per month with annual payment.

Obsidian

Focuster

Focuster not only helps to fix tasks but also to control their execution. For example, if you enter a task, the service will block it for a certain time and include it in the daily schedule.

Advantages

Modern interface.
Structurally, Focuster is divided into two or three parts (depending on which calendar you choose: for the day, 4 days, or the week).
In the daily calendar, there are 3 blocks: on the left - folders with tasks, in the center - a list of tasks for the day where you add a task, and it automatically duplicates in the block on the right, where tasks for the day are already divided by hours.
Simpler with the 4-day and weekly calendar, there are not so many elements - only the block with folders and the block with days of the week.
Various calendar formats: daily, weekly, and 4-day schedules.
Kanban boards and daily schedules - on one screen.
Synchronization with Google Calendar.

Disadvantages

Overloaded interface.
Cannot add subtasks.
No version for Android, and the iOS version is underdeveloped.
Difficult to use for team work - no onboarding, unclear how to delegate tasks, monitor employees' work, etc.

Pricing

Two subscription options: Basic — 590 ₽ per person per month (but there are limitations - no Trello integration, time blocking, etc.) and Pro — 1100 ₽ per person per month without limitations. Upon registering in Focuster, a trial Pro period of 14 days is immediately activated to help you decide if the service suits you and if you need a Pro subscription.
