## What is Dewie?

Streamline impaired-driving documentation with Dewie, the field app for law enforcement officers conducting Standardized Field Sobriety Tests (SFST), ARIDE assessments, and Drug Recognition Expert (DRE) evaluations. Dewie walks you through each evaluation with built-in NHTSA instructions, captures structured results as you work, and produces court-ready PDF reports, with zero generative AI.

Key Features:

Guided SFST Workflows: Step-by-step Horizontal Gaze Nystagmus (HGN), Walk and Turn, and One-Leg Stand testing with on-screen instructions in English or Spanish.

ARIDE and DRE Support: Complete ARIDE supplements and full 12-step DRE evaluations when your department has granted the matching certifications, including interactive diagrams that carry through to the PDF.

Works Offline: Draft evaluations and queue completed reports without cell service. Dewie syncs automatically when you are back online.

Instant PDF Reports: Generate clean, consistent PDFs from your results and share them through the system share sheet for case files and records systems.

Officer-Authored and Immutable: Every report is written by you. Once submitted, reports cannot be edited or deleted, so the record stays defensible.

No Location Tracking: Dewie does not capture GPS or require a location field. Built for the roadside, not surveillance.

Web Portal Access: View reports from dewie.app. Department administrators can manage seats, invite officers, and review department reports.

Enhance DUI enforcement with Dewie: structured documentation, field-ready offline support, and professional PDF output when accuracy matters.

### 5/5 — Cuts Paperwork Headaches Down

*2024-10-12*

I hate having to deal with all the paperwork it takes when processing a DUI. This app definitely streamlines the process. It walks you through the steps in the SFST Maneuvers, then, cracks out a report you can attach to your narrative when you hit “Submit.”

Literally cuts at least 30 minutes of time off the back end, let alone the time for review and trial, etc. 

Well worth the subscription price for my sanity.
