Photos, notes, time entries, mileage, chat. All queue on the device when signal is gone. Syncs the second you have bars again. Basement remodel, pump room, rural build, mechanical closet. Doesn't matter.
New pool sites in Tampa Bay routinely start life as a dirt lot with no wifi and one bar of cell. Every PM tool I demoed assumed a broadband signal. Photos would not upload. Time punches would not save. Daily logs died on submit. That is The Field-Office Latency Gap on hard mode, hours between what happened on site and what the office sees. Workhand queues actions offline, drains them when signal comes back, and shows the office a sync-status pill so nobody has to guess.
Add a job cost without signal. The row shows up immediately. The receipt photo queues alongside it and uploads when connection returns.
Clock in in the basement, clock out on the truck. Active timer banner stays accurate with zero bars. Hours land in the report when sync runs.
Write notes, attach jobsite photos, save. Images queue with the log and upload together when signal returns. Photo and text stay tied.
Log the trip on the drive back to the supply house. IRS-rate write-offs don't depend on signal. Queues and syncs like everything else.
Send job-thread messages with photo attachments. They show up in the thread right away and reconcile with realtime when the app reconnects.
Queue drains within about 30 seconds of getting bars back. Success toast tells you what synced. Pill in the header clears itself.
Add costs, log time, send chat, snap a receipt, write the daily log. Same taps as always. No offline switch to flip.
Each change writes to local storage. A pill in the header shows a live count of pending items. Nothing gets lost to a crash or a dead battery.
Queue drains in about 30 seconds. Photos upload. Chat reconciles. The dashboard catches up. A green toast confirms the count.
Most construction apps treat offline as "show cached read-only data." Workhand's offline mode is write-capable. Every action that changes the database works without signal, persists across app restarts and phone reboots, and shows you exactly what's pending.
On a Land O' Lakes shell dig in 2024, my excavator burned four hours in a no-service pocket that day, and I lost every time punch and every photo when he tried to sync at the truck. He ended up rewriting the log from memory. Contract was $195k, I was already thin on margin, and a lost half day of documented time hit me at the close-out. Workhand's queue holds every photo, every note, every time entry offline, so nothing gets rewritten from memory.
