How to Capture GPS Location with Timestamp at Submission Time?

Users often ask:
"I want my form to log the exact coordinates along with a timestamp when the user hits submit and capture photos with this data stamped on them. How do I automatically add GPS coordinates, date, and time stamps directly on photos when someone submits my form? How accurate is this across devices, and how can I set it up?"

The answer: Configure Clappia's blocks to automatically capture location and timestamp data, then stamp this information directly onto images using the Camera block's Image Text feature.

Why Capture GPS Location with Timestamp on Photos?

Logging exact user coordinates with a submission timestamp helps track field operations, validates location-based service deliveries, ensures compliance, and enhances accountability. It enables automated real-time location capture without manual input, reducing errors and improving process transparency. Stamping location and time directly on images prevents disputes and provides instant verification of when and where photos were taken.

Step-by-Step Guide: How to Add GPS Location with Date and Time Stamp on Photos

Step 1: Add Required Blocks

add gps location, time, date blocks

‍

In your app designer, add these blocks based on your use case:

• GPS Location block - Captures coordinates and address
• Date Selector block - Records the date
• Time Selector block - Records the time
• Camera, Images & Files block - Captures photos with stamps

Step 2: Enable Automatic Data Capture

Configure each block to automatically capture current data:

GPS Location Block - Click the block, go to Advanced tab, enable the "Default to current location" toggle. This automatically captures user's coordinates when they open the form.

Date Selector and Time Selector Blocks - Similarly, go to their Advanced tabs and enable "Default to current date" and "Default to current time" toggles respectively.

Step 3: Configure Camera Block to Stamp Data on Photos

‍

Click the Camera, Images & Files block and configure:

In Basic Tab:

Set "Allowed file types" to "Images (Camera Uploads)"

This forces users to capture images from their phone camera or web camera (not upload old photos from galleries). For this option to work, ensure only "Images (Camera Uploads)" is selected in File Types.

In Advanced Tab:

1. Find the "Image text" box
2. Type @ to see the list of available variables from your app
3. Add this text format using the '&' operator:

'GPS Location: ' & {gps_location} & ', ' & 'Date: ' & TEXT({check_in_date}, "DD-MM-YYYY") & ", " & 'Time: ' & TEXT({check_in_time}, "hh:mm")

‍

What this does:

• {gps_location} - Adds GPS coordinates
• TEXT({check_in_date}, "DD-MM-YYYY") - Formats date as DD-MM-YYYY
• TEXT({check_in_time}, "hh:mm") - Formats time as HH:MM

Important: Variable names depend on the labels you set for each block. In this example:

• {gps_location} is the variable for a GPS Location block labeled "GPS Location"
• {check_in_date} is the variable for a Date Selector block labeled "Check In Date"
• {check_in_time} is the variable for a Time Selector block labeled "Check In Time"

When you type @ in the Image text box, you'll see all your app's variables. Select the correct ones matching your block labels. Learn more about labels and variables.

What this does:

• Adds GPS coordinates from your GPS block
• Formats date as DD-MM-YYYY using the TEXT() function
• Formats time as HH:MM (hours:minutes)

Optional: Add employee name by including: & ', Employee: ' & {submitter_}

Click Save.

Now every photo captured will automatically display GPS coordinates, date, and time stamps directly on the image.

Step 4: Test Your Setup

• Open the app on your mobile device
• Grant location permissions when prompted
• Capture a test photo
• Verify GPS coordinates, date, and time appear stamped on the photo

Using on Mobile Devices:

• Download the Clappia app from Google Play Store (Android) or Apple App Store (iOS).
• Login with your credentials and open your 'GPS location with timestamp App' to start capturing photos with automatic location and time stamps.

How GPS Location Block Works

• Automatic Location Capture: The GPS Location block captures the device's current latitude, longitude, and address automatically when the user submits the form.
• Coordinates and Address: Besides raw GPS coordinates, the block resolves the address to give a meaningful location context.
• Geofencing Support: This optionally restricts data capture within specified geographic boundaries (closed areas). Learn more about Geofencing with Clappia.
• Permissions Required: Users must grant location permissions on their devices and enable GPS/location services for accurate data.
• Accuracy Factors: Accuracy depends on device capabilities and environment (e.g., urban vs. rural, GPS signal strength). Most modern smartphones provide good precision suitable for business applications.
• Timestamp Logging: Submission time is automatically logged by Clappia’s backend when the data is sent, coinciding with location capture.
