The App is now compatible with iOS 26. iOS 16 and below are no longer supported. Fixed a problem that occurred when only "Contact Input" was selected as the condition for RTR500BM's Warning Contact Output, where the Contact Output Setting was displayed as "OFF" on the Warning Settings screen. Fixed a problem that caused abnormal application termination under certain conditions.

Fixed a problem where the "Passcode Error" was displayed when changing the Remote Unit's passcode and turning off Bluetooth at the same time. Fixed a problem where the screen layout was distorted when entering a scale conversion equation for RTR505B-P and RTR-505-P and returning to the previous screen. Some changes have been made related to the Remote Unit Firmware Update. For details, please refer to the Software/Apps page of T&D website.

Added a function to update the firmware of multiple Remote Units simultaneously. In the registration process via Bluetooth, the Remote Unit's Bluetooth setting can no longer be turned off.

The App is now compatible with iOS 18. iOS 15 and below are no longer supported. Added the firmware update function for RTR501B/502B/503B/505B/507B. Fixed minor spelling inconsistencies (e.g., "View/Register via optical com" changed to "View/Register via Optical Communication" in the View Device Settings and Device Registration menu.)

When deleting a registered Remote Unit or Repeater from the Base Unit, the Remote Unit or Repeater is now initialized automatically. Changed the supported iOS version to iOS14.0 or later. Fixed a problem where RTR-500 (Overseas Model) was displayed as RTR-500C (Japanese Model). Fixed a problem that occurred when changing RTR505B or RTR-505-V’s warning settings via T&D WebStorage Service, they were not displayed in the "View Pending Settings" screen.

Changed the default setting of the Recorded Data Transmission Schedule from Every Day 6:00 to Every Day at an hour determined by the time of first communication between the Base Unit and the App via Bluetooth. Fixed a problem that occurred when making the Scale Conversion for the RTR505B (with PIC-3150 module) on only one channel via T&D WebStorage Service, where the setting was not applied properly. Fixed an issue where the Scale Conversion Equation for the RTR505B (with VIM-3010, AIM-3010, PIC-3150 modules) did not fit on the screen.

Changing RTR500BM’s warning settings is now not allowed when SMS is selected as the warning transmission method (in the Windows software). Added a Help button to the Base Unit Operation Log screen. When registering a Remote Unit using the Initial Settings Wizard, the unit now starts recording immediately.

Changed the app’s primary language from Japanese to English so that the app will be displayed in English on an iOS device that is set to a language other than Japanese and English. The app is now compatible with iOS15. iOS 12 and below are no longer supported.

Fixed a problem that occurred when registering a Remote Unit with a new group via T&D WebStorage Service, where the message “There are unapplied settings” was displayed even though the setting was successfully applied. In the Base Unit’s Basic Settings > Clock Settings, the Current Time is now updated with the daylight savings time information.

Added support for the RTR-602.
