The SFST Report app was designed to let Law Enforcement Officers save time and efficiently take notes during field sobriety tests.

LEOs can easily use this app to take SFST related notes, generate a report, email it to themselves and erase the data from the app.

“This app is great! My agency is buying it for whoever asks for it because of how well the report is detailed already. This is truly a huge deal! Again, thank you so much!”

“What an awesome job!! Your hard work has significantly reduced the work I have to do in the field! I use this app every shift! Thank you for everything!”

- Vehicle in motion section

- Note taking for driver and vehicle information (driver name, gender, vehicle brand, license plate, ...)

- Driving license scanning to load the driver's info automatically

- Note taking for the following tests:
** Horizontal Gaze Nystagmus test (HGN)
** Walk & Turn test
** Lack of Conversion test
** One Leg Stand test
** Finger to Nose test
** Modified Romberg test
** Hand Pat test
** Hand Coordination test
** PBT results

- All tests have instructions (except for the lack of conversion test) for the officer to remember how to run the test and what to tell the driver.
- The conversation with the driver is in English and Spanish. The text in Spanish can be played as audio files to communicate with the driver.

- SFST report generation, preview and export by email

- Data deletion from the app once the report is exported

- Option to secure the app with Face ID or Touch ID. This way, only the officer can open the app.

- Dark mode to reduce the amount of light coming from the app at night. It makes the app easier to use in low light conditions.

The app is well organized, easy to use and intuitive. It was built with input from law enforcement officers.

Note: We plan to update the app regularly to add more tests and features so please let us know how we can improve this app by sending us an email (from settings page)

Good, solid App!

I have been using this app for almost a year and the improvements have made it hands down the best app I have found for the iOS platform.

I agree that adding a few things such as a section for Chemical Analyst and Intox testing would make it that much better and a complete DWI app vs. just the SFST. Also, for walk and turn, re-arranging the check boxes to run left to right instead of top to bottom would be much easier to input, along with a description narrative on how the turn was wrong. The last thing I would like to see would be a voice record box so that the officer could speak the steps missed and then go back and mark them off bc it does happen quickly.

I recently noticed that the pricing structure has changed and it has become a monthly service instead of a one time purchase. While I do love this app, I would not have originally purchased the pro upgrade as a monthly subscription.

Useful but needs more

So I use this app a lot. DUI’s are big and prominent in my area for sure and this app makes it pretty easy to get a quick little guide down for your Fields. I do with they added a way to put the blood analysis in and also just counted the clues once you submit your test results. I think it’d make it a tad quicker and overall just better. Truthfully don’t have much to complain about with this app and recommend it to everyone especially those who don’t handle DUI’s regularly.

Awesome Tool

This is a great tool to help the Law Enforcement officers ensure convictions and keep drunk drivers off the street!the app to help me keep track of all of my DWI notes. It's missing two article and that is "was the vehicle in motion?", "Did the vehicle cross the centerline/fog line?" That will help strengthen your probable cause. The app does freeze at some parts but once you close it re open it, issues are solved. Not bad for the report either!! Get the app! A few of these updates were added!! Simple and stunning!
