3,900 technicians run their entire workday on the device they already carry — with or without a signal.
The technician is the person who actually keeps the building running. They are also the person who, in most FM operations, has the worst tools. A shared tablet that needs a WiFi connection. A paper checklist that gets filed in a binder and never referenced again. A back-office system that was designed for a coordinator's desk, not for someone standing in a plant room at 2 am. The mobile field app is not a portal that happens to work on a phone. It is an application designed around what a technician actually does on a shift: receive a job, navigate to the asset, confirm the work scope, complete the checklist, capture evidence, consume parts, and get a sign-off. Every step of that flow is designed for one hand, in poor lighting, without a reliable network connection. The offline capability is not a fallback — it is a requirement. Plant rooms, basements, parking levels, and remote buildings all have patchy connectivity. The app works fully offline, queuing all actions and syncing when connectivity returns. Technicians work the same way whether they have signal or not.
The mobile app is where the management system meets the physical world. All the PPM schedules, all the SLA rules, all the asset hierarchies — they only have value if the technician in the field has access to them and can act on them.
Coreziyo’s mobile app is built for field conditions: offline-first, QR-scan-driven, single-handed in the flow of work. A technician does not need training to use it because the workflow mirrors what they already do — arrive, scan, check, fix, photograph, sign off. The app automates the administrative layer around that workflow, not the work itself.
The side effect is management-quality data at scale. Every job produces a timestamped, photographed, signed-off record. Disputes with clients are resolved by showing the completion evidence. Compliance reports are generated from real execution data, not from coordinator estimates. And the technician’s time — the most expensive variable in FM operations — is tracked and allocated without any manual timesheet work.
What you actually get
Offline-first work execution
Full work order lifecycle — receive, accept, execute, close — operates without a network connection. All data queues locally and syncs automatically when connectivity returns, with no manual intervention required.
Asset QR / barcode scan
Scan the asset tag to pull the full history, last PPM date, outstanding defects, and relevant checklist for the job type. No searching, no manual entry — the asset context arrives with the scan.
Checklist and photo evidence
Configurable checklists per job type with mandatory fields before closure. Photos and video captured in-app are stored permanently against the work order — never lost to a WhatsApp group or a deleted camera roll.
Digital sign-off and client acknowledgement
The client or supervisor signs on the technician's screen. Sign-off timestamp and signature image are stored with the work order. Disputes about whether a job was completed are eliminated at source.
Parts lookup and consumption logging
Search the parts catalogue, check warehouse stock levels, and log parts consumed against the work order — from the field. The draw posts to the work order cost and updates inventory in real time.
GPS check-in and technician timesheet
Automatic GPS check-in when the technician arrives on-site. Labour time is captured from job acceptance to sign-off without manual timesheet entry. The data feeds both cost allocation and attendance tracking.
How it shows up in real operations
A typical day for a Coreziyo-equipped technician at the GCC reference operator: the shift starts with a push notification — three PPMs and two reactive jobs scheduled for the day, with locations, asset details, and checklists already loaded. The first job is a chiller inspection in a basement plant room with no signal. The technician scans the QR code on the chiller, pulls up the maintenance history, works through the checklist, photographs the completed items, and closes the job. The app queues the closure and syncs the moment they return to signal range. By mid-morning, a new reactive job has been assigned in real time — a tenant-reported fault two floors up. The technician accepts it on the phone, navigates to the location, photographs the fault before and after, consumes two parts from their van stock, and gets the tenant's digital sign-off. The cost posts automatically. The asset record is updated. The coordinator's queue shows the job as closed without anyone making a phone call. Across 3,900 technicians and 150,000 work orders a month, the mobile app is what makes that volume manageable without an army of coordinators.
