Personal Injury App Development Β· US Market

From Accident Scene to Signed Retainer β€” On Their Phone

One missed after-hours PI lead can cost $15,000–$75,000+ in contingent fees.

We build branded client portals and mobile apps with injury-type intake, accident photo upload, e-sign retainers, milestone push, and CasePeer / Filevine / Clio sync β€” so U.S. personal injury firms capture cases before competitors call back.

The revenue drain

While your office is closed, injured clients are signing with competitors

Most PI leads search on mobile nights and weekends β€” right after the crash. A generic PMS portal does nothing for that moment.

The contingency math is brutal

If you miss five after-hours leads a month and even two would have become car retainers at $25,000 average contingent value, that's $50,000/month walking to the firm that answers first. A custom intake app closes that window.

Bundled portals don't win the crash moment

CasePeer and Filevine portals help after the case is open. They do not replace branded injury-type intake, scene photo capture, and retainer e-sign when someone is still standing on the shoulder.

The 5-minute conversion cliff

Lead response odds collapse after the first minutes. When a Sunday night inquiry sits until Monday, the prospect has already spoken with two other PI firms. Speed is now a core competitive advantage.

Deliverables

What we build for personal injury law firms

Every feature closes a specific revenue leak β€” from after-hours missed calls to status-call overload to unsigned retainers.

Branded PI client portal

Secure web and mobile login with your firm's branding β€” clients see your name, not a generic CasePeer or Clio label.

Injury-type intake forms

Separate flows for car accidents, slip & fall, truck crashes, and wrongful death β€” mapped to your matter types.

Accident photo & doc upload

Clients capture scene photos, medical records, and insurance cards directly from their phone after an accident.

E-sign retainer & medical auth

Digital contingency agreements and HIPAA-aware medical authorization forms β€” signed before the first office visit.

Case milestone push notifications

Demand letter sent, settlement offer received, deposition scheduled β€” clients stay informed without calling your office.

PMS integrations

CasePeer, Filevine, Clio, MyCase, PracticePanther, and Smokeball API sync β€” no forced migration from your current stack.

Feature β†’ intake bridge

Every feature maps to a signed retainer or a retained client

We do not build vanity apps. We build the shortest path from crash to contingency agreement β€” then keep clients informed so they stay.

Built for the phone in their hand at 11pm

PI demand does not wait for business hours. Your app must capture intake, push updates, and keep clients from calling β€” or shopping β€” mid-case.

How it works

Our PI app development process

Fixed scope. Fixed price. Working software every two weeks.

01

Discovery & Revenue Scope

We map your after-hours call volume, injury-type mix, and PMS stack β€” then define the minimum build that closes the retainer leak. You leave with a clear scope, fixed price, and delivery timeline.

02

Build & Integrate

Branded UI, encrypted back-end, injury-type intake, and PMS integration delivered in two-week sprints. You test against real PI matters at every sprint review β€” no surprises at launch.

03

Launch, Scale & Iterate

App Store submission, staff training, and client onboarding support. Quarterly reviews add new injury pathways, push rules, or integrations as your practice grows.

Build vs. buy

Every option evaluated honestly

PI firms typically evaluate four paths. Here's how they compare across the factors that actually matter.

Security standards

Enterprise-grade security for PI medical data

Accident photos, medical records, and contingency agreements are among the most sensitive data your firm holds. Security is default β€” not an add-on.

  • AES-256 encryption at rest

    Medical records and case files protected at every storage layer

  • TLS 1.3 in transit

    All data encrypted between client, app, and servers

  • MFA & biometric login

    Only authorized clients access sensitive case information

  • HIPAA-aware document handling

    Medical authorizations stored with role-based access and audit logs

  • Audit trails on all messaging

    Every client-attorney interaction logged for compliance

  • 100% code & IP ownership

    Full source code and IP transfer at launch β€” no lock-in

The ROI math

One retained PI case pays for the portal

Run it for your firm. Contingency economics make custom intake infrastructure one of the highest-ROI tech investments in plaintiff practice.

After-hours leak vs. mobile intake capture

Intake calls arriving after hours40–60%
Status-call reduction with push updates~50%

Framed from industry intake studies + PI portal benchmarks (Case Status call-reduction claims) + Legal Length PI cohort results.

Frequently asked

PI app development questions, answered

The questions personal injury attorneys ask before committing to a build partner β€” answered directly.

  • Should my PI firm build a custom app or use the bundled CasePeer / Clio / Filevine portal?

    Bundled portals work when clients accept a generic PMS experience and you only need basic messaging and document share. Custom PI app development makes sense when you need branded mobile intake, injury-type questionnaires, accident-scene photo upload, medical-authorization e-sign, or push workflows your PMS does not offer natively. We scope the smallest build that closes the revenue leak β€” often a secure portal first, with native iOS and Android when push and offline access justify the investment. You keep CasePeer, Filevine, or Clio; we extend them.

  • How fast does a PI client portal pay for itself?

    Faster than most managing partners expect. One signed car-accident retainer commonly runs $15,000–$75,000+ in contingent fees. A portal-only build starts around $25,000–$35,000. Recover two after-hours leads your competitors would have signed, and the build is paid for. Add status-call reduction and higher review scores, and the ongoing ROI compounds every month.

  • Do you integrate with CasePeer, Filevine, Clio, MyCase, and Smokeball?

    Yes. We build custom client portals and mobile apps as a front-end layer on top of your existing practice-management system β€” syncing matters, contacts, documents, and calendar events via secure API. You keep your current PMS; we extend it with PI-branded intake, push notifications, and injury-type workflows without forcing a platform migration.

  • How long does a PI client portal or mobile app take to build?

    A focused client portal with secure login, injury-type intake, document upload, e-sign, and case status updates typically ships in 8–12 weeks. Full native iOS and Android apps with push notifications, accident photo flows, and PMS integration run 12–20 weeks depending on scope. We work in two-week sprints with working software you can test against real matters.

  • How much does personal injury app development cost for U.S. law firms?

    Portal-only builds start around $25,000–$35,000. Native iOS and Android apps with PMS integration, injury-type intake, and push notifications typically range from $40,000–$90,000 depending on integrations and feature depth. We provide a fixed-scope quote after discovery β€” no open-ended hourly billing.

  • Do I own the app source code after launch?

    100%. Full source code, design files, App Store accounts, and deployment documentation transfer to you at launch. No proprietary lock-in, no monthly platform rental tied to our stack. You can move to any developer or host at any time.
