Why CoordBase
Built for the work
Built for the work
you actually do.
The big platforms try to do everything for everyone. CoordBase focuses on the core features construction teams really use — and makes each one fast, dependable and simple — so your daily tasks get smoother, not heavier.
Works where you work
CoordBase keeps working with zero bars.* A record finished offline waits as Ready to issue and gets its number when you reconnect.
Simple, fair plans
Simple yearly plans per person and no per-project fees. Free trials never charge by themselves — they stop and ask.
Your data stays yours
Make a complete backup any time. If a plan ends, your cloud copy is kept for at least 90 days so you can download it.

What makes CoordBase different?
Focus. CoordBase gives you the core features construction teams actually use — drawings, records, punch lists, RFIs and submittals — and makes them fast and dependable, on site and in the office. It works with zero bars, plans are simple and per person, and your data stays yours.
Does it work without an internet connection?
Yes. Personal: everything stays on your device. Company: each phone keeps the jobs it needs, and you can mark important jobs Keep Downloaded, so crews keep working without signal. A few things wait for a connection: a record’s number (it waits as Ready to issue), Share Links, and files not kept on that phone. A company phone checks in with the company at least every 3 days.
Personal or Company — which do I need?
Personal is for your own work: Local keeps everything on your iPhone and iPad, and Cloud adds all your devices and the web. Company is for teams: the company owns its projects, Managers decide who works on which project, and when someone leaves, the company keeps everything.
Is there a web version?
Yes. CoordBase Web is the full app in a browser for the office — import drawing sets, mark up sheets and follow the same records the field issues.
What happens to my data if my plan ends?
Your data stays yours. You can make a complete backup any time, and after a plan ends your cloud copy is kept for at least 90 days so you can download it.
Is there a free trial?
Yes — for Personal and for companies. No card is needed, and a trial never charges by itself: when it ends, it stops and asks you to choose a plan.
