How we built it for you

Your data stays on your phone — not our servers.

Sensitive fields blacked out on your device before anything uploads.

Documents deleted the moment your scan finishes.

Built to SOC 2 security standards.

No subscription. Credits never expire. We'll buy them back if you don't use them.

Extensively tested for real people — not just minimum compliance.

01
Fraud Guardian

Fake documents have tells. Now you can see them.

Upload the pay stub, rental application, photo ID — Cross-Check compares all of them against each other. Dates that don't line up. Small math errors on pay stubs. Inconsistencies between what one document says and what another one doesn't. AI is surprisingly bad at math and makes small errors... unless you build it just for that, and we did.

  • Cross-Check compares every document against every other one
  • Catches math errors, format anomalies, and inconsistencies across docs
  • Flags dates and figures that don't line up between documents
  • 3 credits per scan, minimum 2 documents

Maintenance Guardian

Know what's failing before it fails.

Snap a pic of the nameplate on your HVAC. It reads the model number, looks up manufacturer lifespan for that exact model, and tells you how many years it has left — adjusted for your location. Grab a pic of the roof and it factors in what it actually looks like. Not generic estimates.

  • Reads model numbers from HVAC nameplates
  • Looks up manufacturer lifespan data for that exact unit
  • Adjusts for climate and regional usage patterns
  • Works on roofs, units, and other major systems

Who the hell is Jeff from RentalGuards?

The wife and I bought our first rental at 21 with no idea what we were doing. Still figuring it out 25 years later — including how to build an app.
