About this app

LD Atlas provides full control and real-time monitoring with the ability to download, view, generate reports and share data. The best app on the market for working with noise dosimeters and the 821/721 models.

LD Atlas also replaces the HVM200 Control App and the AudCal Audiometric Calibration App.

For Spartan 730, 730IS, 821, and 721 these Atlas features are available only from Larson Davis:
o Full meter setup and configuration
o Real time monitoring of all meter metrics
o View file list and download data files

Ratings and reviews

The app allows me to talk to my meters and perform my audiometer calibration. It sometimes runs slow when I first open the app and I have to correctly switch my wifi but it works.

New update broke the app, constantly says location services disabled when locations is on and the app has location permissions. This app is now useless and I can not monitor my meters in the field absolutely screwing me on my current project. Thanks LD

Helps me easily control my Larson Davis devices.
