LDLOCK APP 3.0 Officially Released: New Interface, Doubled Management Efficiency

Version Overview

LDLOCK APP 3.0.0 was released globally on December 20, 2024, as a major update. Developed by Zhejiang Lading Technology Co., Ltd. (FANDAN), founded in 2016 and headquartered in Yongkang, China’s Hardware Capital, Version 3.0 is built on real-world experience from over 10 million installed devices across 28 countries. The release fully rebuilds the mobile architecture and UI, delivering a faster, safer, and more intuitive lock-management hub for apartment operators, Airbnb hosts, property managers, and maintenance teams.

New Features

• **Home Device Dashboard**: Aggregate real-time device status on one screen and eliminate the need to check locks one by one.

The new customizable Home Dashboard supports drag-and-drop grouping by building, floor, zone, or project. Upon login, users see at a glance which devices are online or offline, battery levels, and alert tags such as tamper, low battery, or offline timeout—no need to drill into individual detail pages. The dashboard syncs with the cloud in real time and is fully compatible with F25, P30, F9PRO+, G20PRO, F19, and F15 among the 19+ on-sale models, while automatically filtering sensitive asset information according to sub-account permissions.

Use cases: Morning roll-call inspections for centralized apartment operators; district-level health checks for property management companies; overseas landlords monitoring international assets remotely.

• **Batch Key Lifecycle Management**: Generate, issue, recover, and freeze keys in bulk throughout the entire lifecycle.

The Keys module now offers a batch workflow. Administrators can simultaneously create time-limited passcodes, IC cards, or Bluetooth keys for F17, F11, F10PRO, F8PRO, and B60, and bulk-import tenant phone numbers and lease periods via Excel. The system automatically aligns activation and expiration times. Both tenants and managers receive renewal alerts 24 hours before expiry; keys auto-freeze afterward and move to a recycle bin, completely eliminating disputes caused by forgotten manual deletion.

Use cases: End-of-month tenant turnover at long-term rental apartments; bulk summer and winter vacation authorizations for school dormitories; temporary access distribution for exhibition centers.

• **Automated Maintenance Workorders**: Turn device anomalies into tracked workorders automatically.

When networked locks such as F9AUTO, F9S, F9SE+, and F9PRO+, or K3 access control and smart meters report low battery, tamper, repeated passcode errors, or offline timeouts, the App automatically generates a standardized workorder and pushes it to the nearest technician based on geography or responsibility zones. The workflow supports photo upload, spare-part requests, on-site notes, and electronic owner sign-off, creating a full audit trail manageable from a phone.

Use cases: Remote management of scattered short-rental properties; standardized maintenance for large communities; compliance inspections for public-rental housing.

• **Tiered Permissions & Sub-Accounts**: Granular control down to a single lock, a single user, and a single time slot.

A new four-level permission model—Super Admin, Project Manager, Technician, and Tenant—lets super admins restrict sub-accounts to viewing only designated buildings’ devices such as P40, P60, FH01, and F21, or allow temporary-passcode issuance only while blocking master-key deletion or record export. All sensitive actions are logged immutably and support timeline audits, meeting corporate governance requirements.

Use cases: Regional managers at chained apartment brands delegating authority; state-owned public-rental platforms enforcing tiered control; multi-campus university logistics groups isolating permissions.

• **Offline Task Queue**: Execute commands in weak-signal environments without spinning wheels.

For underground garages, old corridors, and remote sites, 3.0 caches unlock, time-sync, access-log retrieval, and room-status sync commands in a local task queue. When the technician’s phone comes within Bluetooth range of F25MINI, FF01, FF03, or FF06, the App auto-executes the queued commands and uploads results once the network returns—no repeated trips to find signal or manual retrying.

Use cases: Underground warehousing parks with poor cellular coverage; maintenance in older community utility wells; daily operations in regions with underdeveloped network infrastructure.

Improvements

• **Dramatically faster response**: Local database indexing and cloud API concurrency were rebuilt. Cold-start speed improved by approximately 55%, and frame rates for scrolling through thousand-device lists stay stable at 58 FPS (lab-tested). For high-frequency tasks on F7PRO+ and B60, the average round-trip time from App command to lock execution dropped by 40%, cutting wait times for both managers and tenants.
• **More stable Bluetooth connectivity**: For Bluetooth-direct models such as FF06, F8PRO, F21, and F25MINI, the reconnection mechanism and broadcast filtering were optimized. Pairing success in complex electromagnetic environments rose to 98.2% (internal testing), with no noticeable interruption across 10 consecutive lock configurations.
• **Smaller package, lower power consumption**: Installer size was reduced by 32%. Intelligent frequency scaling for background location and Bluetooth scanning cuts power use by 25% over an 8-hour shift, improving performance on mid- and low-tier Android devices.
• **Refreshed visual and interaction design**: A new card-based layout and semantic color system expand critical button hit areas by 20%, reducing mis-taps for technicians wearing gloves in winter. Step-by-step guidance was also added for remote provisioning of P20 and P40 models with screens, allowing beginners to complete initialization independently.

Bug Fixes

• Fixed occasional crashes and audio-video desync when viewing real-time video on F9PRO+ and B50 video locks on certain Android devices.
• Fixed time-format errors and daylight-saving-time drift for K3 access control and E5 card encoder in Spanish, Russian, and Arabic environments.
• Fixed an occasional sync bug between cloud and local states for power switches when batch-deleting keys under unstable network conditions.
• Fixed invisible buttons in permission dialogs and overlapping text on configuration pages under iOS Dark Mode.
• Fixed missing notification-bar icons for smart water and electricity meter alerts when reported at extremely low battery levels.
