Shift Comparison is a personal tool that allows you to compare your previous and new work schedules to check for changes. It is designed to be reflected only after you have reviewed and personally approved the changes.
**Compare work schedules from two points in time**
By comparing previous and new data, it identifies added or changed shifts, as well as candidates for deletion. You can review the changes before applying the comparison results.
**Select only necessary changes**
You can directly select the items to approve and defer the rest. Duplicate identifiers are not imported. If the date of the same external ID changes, or if a value you have manually modified conflicts with the new data, it will not be reflected until you confirm. Approved changes are recorded for future verification.
**Free Use**
You can use the service for free up to 2 change approvals per month (Seoul time). Approving multiple items at once counts as one approval. You can increase the limit for additional change approvals with a subscription. Please check the actual product and price displayed on the purchase screen.
Viewing, editing, comparing, exporting, backing up, and restoring existing work schedules are available regardless of your subscription status. Existing data is not locked, and restoration is not restricted to a fee.
We handle only your own data. We do not provide official railway timetables, real-time operation and dispatch information, or automatic analysis of agency data. Please check the original work schedule and agency guidelines before applying changes made in the app to your actual work.
Work data is managed on your device. You can use the app without account sign-up, synchronization with our own server, or advertisements.
Review the changed schedules of the two worktables and personally approve the changes to be reflected.
