Your Business in Your Pocket
Native iOS app built by window cleaners, for window cleaners. Full offline functionality means you work anywhere—even 30 feet up with no signal.
Offline Mode
Why Offline Functionality Changes Everything
Most field service apps require constant internet. Sergio doesn't. Here's why that matters when you're on a ladder.
Other Apps (Internet Required)
- App crashes when signal drops at job site
- Can't log completed jobs without WiFi
- Navigation stops working mid-route
- Can't create invoices until back in office
- Customer details unavailable on ladder
Sergio (Offline-First)
- Full app functionality without internet
- Log jobs, create invoices, take notes anywhere
- Turn-by-turn navigation works offline
- Auto-sync when back online (you'll never notice)
- All customer data cached locally (Core Data)
Real Talk: I've been 30 feet up on a ladder with 1 bar of signal. Other apps freeze. Sergio works. That's the difference between getting paid today or manually entering data tonight.
