Build A Case helps you keep a clear, organized record when you are dealing with a landlord, an employer, a government agency, an insurer, or any party you need to document. When you finally file a complaint, escalate to a regulator, or talk to an attorney, you usually arrive with scattered notes, screenshots buried in Photos, and half-remembered dates. Build A Case gives you one place to put all of it. WHAT YOU CAN DO • Log every interaction — phone call, email, in-person, web form, or letter — with the date, who you spoke to, and what was said. • Attach evidence — photos, video, audio, screenshots, and documents — straight from your camera or library. • Mark up a photo and save the annotated copy alongside the untouched original. • See your whole history on a single timeline, so nothing falls through the cracks. • Export a clean PDF case file you can hand to an agency, a regulator, or a lawyer. BUILT FOR TRUST • Every file is fingerprinted with a SHA-256 hash and timestamped, so you can show it has not been altered since you saved it. • Everything stays on your device. There is no account to create and no server we control. Optional iCloud Sync (off by default) keeps your files in your own private iCloud. • Lock the app with Face ID so your records stay private. WHERE TO FILE Build A Case includes built-in reference information for U.S. federal and state agencies and the kinds of issues people commonly document — housing, employment, consumer and financial, insurance, civil rights, education, and more — so you have a starting point for where a complaint may go. PRIVACY FIRST We collect no data, run no analytics, and show no ads. Your case files are yours. Build A Case is a documentation and organization tool. It is not a law firm and does not provide legal advice. It is not a substitute for a licensed attorney or other professional. If you are in crisis, the app links to 988 and other support resources. Free to use for documentation. A one-time in-app purchase unlocks unlimited PDF exports after a 30-day free trial.
