AECOS Crew
Site attendance that knows where the site is.
About AECOS CrewStudio · Site and workforce apps
Field apps your site teams will actually use.
We build construction attendance apps, timesheets, daily progress reports and site diaries for contractors: mobile apps that work offline, check people in only when they are on site and speak your crew’s language.
AECOSYSTEM builds custom labour attendance and field apps for construction sites.
The problem with paper and proxies.
Paper muster rolls are slow to compile and easy to fill in for someone who is not there. Spreadsheets arrive days late. A field app that records attendance where the work happens, with location and time, gives the office a true picture the same day.
What we build.
- 01
Geofenced attendance
Check-in and check-out only inside the site boundary, with a live crew map.
- 02
Timesheets and wages
Hours by crew, contractor and activity, ready for payroll.
- 03
Daily progress reports
Work done, photos, labour and weather, compiled automatically.
- 04
Site diaries and tasks
Instructions, photos, voice notes and follow-ups, with notifications on WhatsApp.
- 05
Offline first
Everything works without a signal and synchronises later.
- 06
Languages
Hindi and regional languages for the people who use the app every day.
What we have built that is relevant.
AECOS Crew, our geofenced attendance app (a geofence per site, a live crew map, attendance reports and an offline mode), and tasqs, our task manager for teams on WhatsApp, are both in development.
Who it is for.
How a project runs.
- Stage 01
Discover.
We learn how your projects, sites and teams actually work before we suggest any software.
- Stage 02
Specify.
We write down what the system must do, in plain language and in detail, so that everyone agrees on it before we build.
- Stage 03
Build.
We build in short stages that you can see and use, starting with the part that saves the most time.
- Stage 04
Launch.
We roll the software out to the people who will use it, on the devices they already carry.
- Stage 05
Support.
We keep the system running, measure how it is used and improve it as your company changes.
The technology we use.
We choose widely used, well-documented tools that we already run in our own products, so the system is dependable today and maintainable for years.

Frequently asked questions.
How does geofenced attendance work?
Each site has a boundary drawn on a map. The app records a check-in only when the worker’s phone is inside it, with the time and location, so proxy attendance becomes much harder.
What if there is no signal on site?
The app records attendance on the phone and uploads it when a connection returns.
Can workers without smartphones be included?
Yes. A supervisor can check in a crew from one device.
