Camera App

Snap work site photos and upload them directly to the job.

Offline Mode

Use key features offline, and sync automatically when back online.

Works offline. Syncs when you're back. Try the app free

Contractors who switched to Cinderblock don’t switch back

Real feedback from teams running real jobs, across electrical, general contracting, and more.

Our office runs itself now

Scheduling used to eat up half my morning. Now appointments go out automatically, customers get notified, and I can actually focus on the business instead of playing phone tag.

Laura, BTB Electric

Works even when the wifi doesn’t

I’m on job sites with zero signal all the time. The mobile app keeps working offline and syncs everything when I’m back in range. That alone sold me.

Luigi, DePinto Electric

They actually listen

We suggested a feature for tracking purchase orders and they built it within weeks. Try getting that kind of response from the big guys.
