OSOI keeps your office and field teams on the same page. Projects, tasks, chat, documents, notes, and time tracking come together in one mobile-first app, so information stays with the work and the people it belongs to. Built for construction, architecture, engineering, facility management, and field service companies, and for any team whose work happens on site and in the office. WHAT YOUR TEAM CAN DO • Time tracking: start recording on a job with one tap, switch to the next with another, and correct times on the spot. Attendance, absence, and vacation are in the same app. • Technician mode: a simpler app for people on the go. The home screen shows the day's jobs, with only the chat, time tracking, and the profile next to it. • Chat: talk in projects, tasks, and groups, and turn a message into a task when something needs to get done. • Tasks: assign people, set deadlines, and add checklists right where the information is. • Notes: capture information on the go and keep it with the project, task, or person it belongs to. • Documents: attach and find project files where your team works, on the phone or the desktop. • Search: search everything and find it in seconds. WHY TEAMS STICK WITH IT • Familiar from day one: if your team knows WhatsApp, they'll know OSOI. No complex training needed. • Made for the phone: easy to use with one hand on site, with the same workspace on desktop and tablet. • Works offline: no signal in the basement? Keep working, and OSOI syncs when you reconnect. • Clients and subcontractors in the project: invite external partners with one click. They see only the projects they're invited to and work with your team in one place. • Everyone knows where things stand: see who's on site, what's done, what's stuck, and who's on vacation or sick leave, without status calls. • Your data stays yours: OSOI does not use your project data to train AI models.

Time recording in every time zone Whether you're in San Francisco or Berlin, your hours land on the right day. Record work on absence days For all those moments when something needs to get done while you're away, you can now record working hours on vacation, sick, and holiday days. Introducing Planner (beta) For admins: one central place to see the recorded and planned work of the whole team. Switch it on in Settings. Large files, reliably Uploading large files now works reliably. ### 1.4.1 — 2026-09-22 In rare edge cases, messages sent in a project thread could get mixed up with messages in task threads. We’ve fixed this issue and also optimized file sending in chats. ### 1.4.0 — 2026-09-17 Introducing Activity Hub: Finally, an answer to “What have we actually done?” Everything that has happened across your projects and your company now lives on one page. Who did what, where, and when, all in one place, in the order it happened. No asking around, no chasing people for updates, no piecing the week together from memory before a meeting. Open it and you know. One time card for the whole day: Recording a day used to mean entering your attendance in one place and your project hours in another. Now it’s one card: start, breaks, end, and the work you did, all entered together, in one go. Work types: Give every recorded hour a type that matches how your company actually works: Office, Business Trip, Workshop, or anything you define yourself. Your hours arrive already sorted, ready for whatever you need them for. Minimum breaks: Choose your country’s statutory break rules for Germany, Austria, or Switzerland, or set up your own. Every day is checked against them, and OSOI either warns you or requires the missing break before the day can be saved. Nobody has to remember the rules anymore. OSOI takes care of it. Overtime surcharges: Set the rules once: when overtime starts and what weekends and public holidays are worth. From then on, every day shows the hours that carry a surcharge, broken down by rate, in your tables and exports. Your bookkeeper is going to thank you for this one. Expenses: Daily allowances, mileage, hotels, parking, and other expenses can now be recorded on the day they belong to, whether your people are on site, at a customer, or out in the field. Set up your expense types once with their amounts, mark which ones should be charged on to the customer, and rule-based expenses are automatically suggested as soon as the day qualifies. Performance improvements: OSOI is quicker than ever. And we’re already working on what’s next. ### 1.3.0 — 2026-09-15 This release is all about time tracking. The improved Time Tracker makes recording your working day simple, from the first tap in the morning to the final timesheets at the end of the day. Start with one tap: Start the clock on your workday with a single tap. You can also track time directly on tasks and checklist items, right where the work happens. See your day at a glance: A visual timeline shows how your day went, with work and breaks side by side. Started a job later or took a longer break? Just drag the time into place. Finish the day in seconds: At the end of the day, check that your time is on the right projects and submit your timesheet. Overlapping time is highlighted, so what you submit is accurate, and your tracked time stays safe even with a weak connection. Keep the Tracker within reach: Show the Tracker on your phone's Home screen, so recording work and breaks is always one tap away. Also new: • Filter tasks by several projects at once, or by individual scopes of work • Favorites appear instantly and stay in sync • Improved and more detailed notifications • A faster, more refined experience across the app ### 1.2.9 — 2026-08-29 Introducing Technician mode for anyone who works out in the field. • Start recording your work with a single tap and tap another task to switch right away • Taking a break remembers what you were doing, so you can pick up where you left off with one tap • A clear view of your day, with a large clock and your work and break totals at a glance • Check and correct your recorded times on the spot • A tidier home screen that keeps the focus on your work Turn on Technician mode in your settings and try it on your next job. OSOI is faster than ever. • Task lists throughout the app open faster and keep working smoothly, even with a poor connection • Choosing a project and recording your time is quicker than before • Timesheets open faster and are easier to read More control • New notification settings • See how much of your plan and storage your team is using • A refreshed language selection • The app now lets you know when a new version is available or required ## Apps similar to OSOI | App | Rating | Price | Category | | --- | --- | --- | --- | | [CheckinPLUS](https://appshunter.io/ios/app/checkinplus/id6756090715) | — | Free | Productivity | | [Memobase](https://appshunter.io/ios/app/memobase/id6502102605) | — | Free | Productivity | | [Evola - AI Work Log & Journal](https://appshunter.io/ios/app/evola-ai-work-log-and-journal/id6752961352) | 5.0 (2) | Free | Productivity | | [INTER-TREUHAND PRACHNER](https://appshunter.io/ios/app/inter-treuhand-prachner/id1599459513) | — | Free | Productivity | | [EdgeEver](https://appshunter.io/ios/app/edgeever/id6792625631) | — | Free | Productivity | | [goals.ai - AI Goal Planner](https://appshunter.io/ios/app/goalsai-ai-goal-planner/id6762310848) | — | Free | Productivity | ## Related topics [routerra teams](https://appshunter.io/ios/topics/routerra-teams) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
