## What is EstimateTrail?

Did the final auto repair bill change from the estimate you approved? EstimateTrail compares repair estimates, saved approvals, work orders, and final invoices line by line—privately on your iPhone or iPad.

COMPARE EACH STAGE
Import or scan the initial estimate, revised work orders, approval screenshots, dated phone notes, and final invoice. Confirm on-device text recognition before comparing.

SEE WHAT CHANGED
Review added or removed work, amount changes, quantity changes, description changes, taxes, and fees. Uncertain matches stay visible for review instead of being forced into a conclusion.

RETURN TO THE SOURCE
Open the original page, photo, or note behind each finding. Export a clear PDF, CSV, or ZIP record whenever you need it.

OFFLINE AND PRIVATE
No account, ads, analytics, behavioral tracking, or document upload. Repair documents and OCR stay on your iPhone or iPad.

ONE PAID DOWNLOAD, COMPLETE APP
Every feature is included after download: full line-by-line results, approval matching, unlimited repair cases, and PDF/CSV/ZIP export. There are no in-app purchases or subscriptions.

EstimateTrail does not estimate fair market prices, diagnose a vehicle, determine whether work was necessary, or decide whether a charge or approval is legally valid. OCR and matching can be wrong. Always check the original documents before making payment, complaint, or legal decisions.
