Sadok

What Happens When You First Open It

Opening the Sadok app for the first time presents a login screen with options to register using a phone number or email. There is no option to skip registration — you need an account to access any features. The interface is clean and straightforward, with a simple color scheme that feels functional rather than flashy. Below the login fields, there is a link to the privacy policy and terms of use, which is standard for apps handling personal data. The app does not ask for any permissions during the initial launch, which is unusual for a preschool management app that might need access to the camera or storage. It simply waits for you to enter your credentials and tap the login button.

Once logged in, the main dashboard displays a grid of cards for different features: Schedule, Attendance, Payments, Media Gallery, Surveys, and Messages. The layout is minimal and focused on delivering information quickly. The app does not push notifications by default; you have to enable them in the settings. This might be a deliberate choice to avoid overwhelming users with alerts. The overall feel is that of a utility tool rather than a polished consumer app. The developers at Wi-Fi Solutions have prioritized function over form, which makes sense for a preschool management app where reliability and information delivery matter more than visual appeal.

How Automatic Payments and Attendance Tracking Work Together

The automatic fee calculation feature and the attendance tracking system are two of the most important features of the Sadok app, but they are not explicitly detailed on the Play Store page. What is not obvious is how these two features interact in a real preschool workflow. A teacher marks attendance for each child at the start of the day, and the app automatically calculates the fees based on the attendance record. This means that parents are only charged for the days their child actually attends, and the system generates invoices automatically. This reduces the administrative burden on staff and ensures that billing is accurate.

The bank API integration adds another layer to this workflow. Once an invoice is generated, parents can pay it directly through the app using their bank account. The payment is automatically reconciled, and the child's balance is updated in real-time. This integration between attendance, billing, and payments is not flashy, but it is functional and serves a clear purpose for preschool administrators who want to streamline their operations. The app's design reflects a thoughtful approach to preschool management, where automation, communication, and financial transparency are all prioritized.

Real-World Performance: What the Data Shows

The app has a small user base, with 1K+ downloads on Android and no visible ratings on the Play Store or APKPure. This suggests the app is used primarily by preschool administrators and teachers in Ukraine, where it was developed. The Android version is approximately 34 MB, which is reasonable for a management app that includes features like media galleries and communication tools. The iOS version is also available, though its size is not specified. The app does not display ads, which is a positive point for a free app. The developer states that data is encrypted in transit and that users can request data deletion.

The version history shows a pattern of regular updates, with the latest version being 1.0.65, updated on June 12, 2026. The changelog for version 1.0.65 includes "Доданий пошук в групових чатах" (Added search in group chats), which indicates that the developer is actively improving the app based on user needs. The app supports Android 7.0 and above, which covers a wide range of devices. The permissions requested are not listed on the Play Store page, but the app's functionality suggests it may require access to the camera for photos, storage for media, and notifications for alerts. Overall, the app appears stable and functional, though the small user base makes it hard to gauge its reliability at scale.

The Permission That Raises a Question

The app does not request any permissions during installation on Android, which is unusual for a preschool management app that needs access to the camera, storage, and notifications to function properly. This could be a deliberate design choice to minimize privacy concerns, but it also limits the app's functionality. Without camera access, teachers cannot take photos of children's activities. Without storage access, they cannot save or share media. Without notification access, parents cannot receive alerts about their child's attendance or payments. The app's minimal permissions are a positive sign for privacy-conscious users, but they also indicate that the app may not be fully optimized for the features it claims to offer. The App Store privacy section states that the developer does not collect any data from the app, which is a strong privacy statement. However, the app's functionality suggests that it may need to collect some data to operate effectively, such as attendance records and payment information. The lack of permission requests raises questions about how the app handles sensitive data and whether it is truly secure.
