Notarized by Apple

Signed with a verified Apple Developer ID and notarized by Apple, so it opens without security warnings.

Private by design

Your messages are read on your own Mac and stored under your account. You stay in control of what is kept.

Verifiable

Every build ships with a published SHA-256 checksum and an Apple code signature you can check yourself.

Litigent ISR — Mission Control dashboard

Mission Control — monitor your case's incoming messages and turn them into organized, court-ready findings, right on your Mac.

Who it's for

Built for the moments that end up in court

High-conflict co-parenting

When every message from your co-parent could matter, ISR captures and organizes them into a clear, timestamped record — so nothing is lost, forgotten, or disputed later.

Preparing for separation or divorce

Start your documentary record early. ISR quietly preserves the communications you receive, so the day you sit down with a lawyer your evidence is already organized.

When trust becomes a legal question

If you suspect your relationship is heading for court, keep a factual, tamper-evident record of what is actually being said to you — proof you can stand behind, not just a feeling.

Any ongoing legal matter

Disputes rarely resolve in a day. For any active legal relationship that needs continuous attention, ISR runs in the background and turns a stream of messages into an organized case file.

Litigent ISR only monitors messages sent to accounts you own and control, such as your own iMessage and email. It is not for accessing anyone else's device or accounts.

Getting started

Install in five steps

  1. 1

    Download the DMG and open it.

  2. 2

    Drag Litigent ISR into your Applications folder.

  3. 3

    Open Litigent ISR from Applications. Because the app is notarized by Apple, it launches without an unidentified developer warning.

  4. 4

    Sign in with your Litigent account.

  5. 5

    When prompted, grant Full Disk Access in System Settings, under Privacy and Security, then Full Disk Access. This lets the app read your own message history on your Mac.

Trust, but verify

Confirm your download is genuine

You do not have to take our word for it. You can confirm the file is authentic and untampered two ways before you trust it, straight from the Terminal.

SHA-256 checksum

Run this in the folder where the download landed, then compare the result to the value below. They must match exactly.

shasum -a 256 Litigent-ISR-1.0.0.dmg
4f8d62ec06b95bcbeb662156ea0dfc10cb57bb7c111393b81290e1fe7f6b0f77

You can also download the checksum file and run shasum -a 256 -c Litigent-ISR-1.0.0.dmg.sha256.

Apple code signature

Ask macOS itself whether the file passes Gatekeeper. A genuine copy returns accepted and source=Notarized Developer ID.

spctl -a -vvv --type install Litigent-ISR-1.0.0.dmg
codesign -dv --verbose=2 "/Applications/Litigent ISR.app"

The signing authority should read: Developer ID Application: Jeffrey Coleman (C9J5246VDV)
