About this app

Connect site and office. Communicate, manage tasks, write notes, share documents, track time, and stay updated—all in one place.

Why teams work better with OSOI:

• Every project, every job site, all in your pocket – See what’s done, what’s not, and what’s urgent across all your jobs.
• It’s simple – If your team knows how to use WhatsApp, they’ll know how to use OSOI. No complex training needed.
• It’s not just another chat app – it’s built for getting work done. Chat like always, but now tasks, timesheets, and updates stay organized.
• Quick check-in on everyone – See who’s on-site, who’s off-site, and what they’re working on. Save yourself hours of phone calls.
• Can’t be deleted. Can’t get lost – Every message, task, and document stays in OSOI. No more missing info, ever.
• Find everything fast – No more digging through emails, WhatsApp, or five different apps.
• Invite clients and contractors with one click and share updates in seconds – No more back-and-forth calls or emails.
• No signal? No problem – Works offline and syncs automatically later.
• Every working hour recorded, every day – No chasing the team for timesheets. Invoice your customers faster.
