## What is Locus Mobile?

System Requirements:

- iOS 13.0 or higher

Description:

Locus Mobile for iOS works in conjunction with Locus’ environmental information management systems. The mobile application is used for simple and accurate data collection and upload from the field, and in the process improves workflow, enables productivity gains, ensures accuracy, and leverages location intelligence. Interaction with Locus Mobile does not require a real-time data connection, and content from the field is uploaded when it is convenient. Field users can work in remote locations with the assurance that all entries are saved and then synchronized back to a secure storage location once they are able to obtain Wi-Fi or cellular data service.

Field data collection requirements and sophisticated data entry rules are configured from within Locus’ system and then assigned to field users and enforced through the mobile device. Field data entries are validated upon entry, and the user is provided with guidance on expected field measurement values. Once data are collected they are uploaded to the parent system for review, analysis, and reporting purposes, where they can also be easily audited for compliance support.

Mobile users are presented with an interactive map interface that shows where sampling locations are and provides status information regarding the required data collection program. The interface supports ad hoc sampling activities that allow users to add sample locations and complete new data entry events.

Locus Mobile application users can take advantage of the inherent location intelligence that has been built in:

- The app is built around a map interface
- Where do I need to go
- Where have I been
- Where am I now
- Status of data collection/sampling is immediately evident using labeling and color coding
- Add new locations on the fly – in the field (ad hoc)
- Locations can be dragged/moved to refine placement
- Delete and start again
- Use satellite background images for improved context

Locus Mobile can be used for processing field data collection operations for multiple users working within the same program. The system can be configured for a wide range of measurements related to well monitoring, air sampling and soil sampling.

Locus Technologies clients are required to opt in to using the Locus Mobile application in conjunction with the client’s Locus environmental information management systems. Locus mobile users are required to obtain a user account from Locus Technologies in order to log into the Locus Mobile application.

The app does not require users to submit payment for content or services within the app. Access and user accounts to the app are granted by Locus Technologies. Contact Locus Technologies via email at info@locustec.com for more information.

The app is primarily meant for distribution in the United States.

## Version history (last 5 releases)

### 4.0.5 — 2026-07-28

Fixed issue where analytical samples displayed in different grids if the Field Sample ID prefix was not the same.
QC samples are now properly moved to selected locations in Soil provisions.
Other minor bug fixes.

### 4.0.4 — 2026-06-19

Fixed an issue when syncing, on a device that multiple users had logged on, the app no longer attempts to upload the other users' provisions.

### 4.0.3 — 2026-03-16

Filterable fields are now properly filtered by location as well as options selected in other fields.

Lengthy record error messages are now wrapped and are no longer truncated.

The Save and Cancel buttons now perform as expected on the location information form.

Edited PDF values are now properly being saved.

Additional pop-up modals from previously opened fields are no longer presented when scrolling the list of fields.

Now, the user should be presented with the location selection as expected, when saving a field sample record from the QC location samples. This should work for both sediment and soil-sampling-based provisions.

The app should no longer proceed with the download portion of the sync cycle if there was an error during the upload request. When clicking the logout button, instead of presenting an alert informing the user they are logged out, the alert instead confirms if the user does want to log out. "Cancel" and "Ok" options are provided, allowing the user to remain logged in, or after confirming, logging the user out and returning them to the login screen.

### 4.0.2 — 2026-02-06

To ensure maximum compatibility, make sure to upload any provisions with un-synced data before installing the new version.

Fixed an issue to allow for logins without network connectivity, after having previously logged in successfully.
Fixed an issue where the View Errors button was not responsive on the Sync Complete screen.
Fixed an issue where the Close button on the Sync Complete screen was navigating back to the login screen.
Fixed an issue where the keyboard was blocking an input dialog under certain conditions.
Fixed an issue where the screen would go blank when attempting to Cancel a record entry form.
Fixed an issue where ad hoc locations could be created without an id.
Fixed an issue where clicking Save more than once on a record entry form would navigate back multiple screens.
Fixed an issue where enhanced groundwater stabilization notifications were being presented for incorrect data types.
Fixed an issue where field measurement grids were unable to correctly select a measurement record.
Fixed some typos and incorrect labels.

### 4.0.1 — 2025-11-28

Bug fixes.
