What's New in BillFighter

1.6.3

September 1, 2026

Accuracy and reliability fixes throughout. - Corrected how we describe debt-collector deadlines. Collectors have no legal duty to reply on a schedule; what the law requires is that they stop collecting until they validate the debt. The app now says so, in both languages. - Hospital and provider bills no longer show a countdown that doesn't apply to them. - Fixed a case where tapping quickly could create the same case twice, or use up two free analyses for one bill. - We now check your remaining free analyses before reading the document, so a scan you can't run doesn't cost you one. - Uploading photos no longer asks for access to your whole photo library. - Resolved cases no longer show as urgent. - Spanish: bill types, letter types and dates now appear in Spanish instead of English. - Accessibility: better contrast, errors are announced by VoiceOver, and more controls are properly labelled.

This app is awesome

After having my son, I was overwhelmed with medical bills. This app was a lifesaver. It alerted me to some issues with my insurance coverage (or lack there of) and provided the steps for me to follow. It can also help you create a dispute letter, making the process very easy. This app helped me save thousands.
