교대근무달력(나는교대자다2)

Opening the app for the first time

No sign-up screen. No tutorial. Just a calendar with a menu button to select your company. That is what you see when 교대근무달력(나는교대자다2) launches. The app sits in the Lifestyle category on Google Play, but its function is closer to a specialized scheduling tool. The interface presents a monthly calendar view. Tapping the menu button reveals a list of companies. Selecting one loads the corresponding shift pattern. The app does not ask for location, contacts, or storage permissions upfront. It simply shows the calendar and waits for input.

What makes this app different from general calendar apps is its focus on shift work. Most calendar apps on Android offer generic event scheduling. This app does not. It is designed specifically for shift workers who need to track irregular work patterns. The result is a tool that is highly useful for nurses, factory workers, and other shift employees but less relevant for office workers with fixed schedules. The trade-off appears when a user's company is not in the list — the app allows manual input or email requests for custom additions. This is not a bug. It is a design choice that keeps the app flexible.

The app is free. No in-app purchases. Ads are present but not intrusive. The 1,000,000+ installs on Google Play suggest a solid user base in South Korea. The iOS version, developed by Maryana Yurieva, is also available on the App Store.

How the company selection and manual input work together

The app's core strength is its company database. Users can select their workplace from a list, and the app loads the corresponding shift schedule. This saves time compared to manual entry. However, not all companies are included. For missing companies, the app offers a manual work input option. Users can enter their shift patterns directly. They can also email the developer to request a new company be added for free. This combination of pre-set and customizable options makes the app adaptable to various workplaces.

This is where the app behaves differently from competitors like "교대달력" or "Shift Calendar". Those apps often require manual setup for every shift. 교대근무달력(나는교대자다2) provides a head start with its company list. The downside is that the company list may not be comprehensive. Users in smaller companies or unique industries may need to rely on manual input. The upside is the time saved for users in supported companies.

For a shift worker who changes jobs, the app allows switching companies easily. The user can select the new company from the menu, and the schedule updates automatically. The manual input option also allows fine-tuning for specific shifts.

What the changelog does not tell you

The Google Play page does not show a changelog. However, APKPure lists version 8.679 with "What's new" details. The developer has not published detailed release notes, leaving users guessing about what changed. The last update appears to be July 2026, according to APKPure, with version 8.679 available. Previous versions include 8.677, 8.673, 8.662, and 8.658. The update frequency suggests active maintenance, but the lack of transparency is a limitation.

What is not in the changelog is any mention of new features. The app has remained functionally identical across updates — company selection, manual input, alarm, lunar calendar. No dark mode. No widget. No push notification customization. The visual design appears unchanged. The developer, Forary (김성표), seems to prioritize stability over feature expansion. The app works on Android 7.0 and above, which covers devices released from 2016 onward. The file size has remained around 8 MB, indicating minimal resource additions.

The update history reveals a pattern of regular but minor updates. The app was first released at least as early as 2012, with steady updates every few months. The 0/61 security scan on APKPure indicates no detected malware. The data safety section states that no data is collected and no data is shared with third parties. This level of privacy is commendable for a free app.

Real-world performance and the alarm feature

A key feature is the alarm function. The app can notify users of upcoming shifts with vibration and screen wake. This is crucial for shift workers who need to remember irregular start times. The alarm can be customized for different shift types. However, some users have reported that the alarm may not always work reliably, especially on newer Android versions with aggressive battery optimization.

Another limitation is the lack of cloud sync. The app does not have a server, so schedules are stored locally. This means users cannot access their schedules from multiple devices. The app also does not support sharing schedules with colleagues or family members. For users who need to coordinate with others, this is a drawback.

The app's privacy practices are strong. The Play Store data safety section states that no data is collected and no data is shared with third parties. Data is encrypted in transit. This level of privacy is rare for a free app. The app does not require any permissions beyond what is necessary for core functionality, making it safe for users concerned about data privacy.
