Video installation guide

Prefer to watch instead of read? This walkthrough covers the download and install steps below.

What you need

• An Android phone or tablet (Android 8.0 or newer).
• A stable internet connection for the download and to activate your license.

How do I install SurveyCalc on Android?

1. Download the app. On your Android device, open your web browser, come to this page, and tap the Download SurveyCalc Android button. The file (SurveyCalc-6.2.2.apk) will download to your device — you'll usually see it appear in your notifications or in your Downloads folder.
2. Open the downloaded file. Open your Files app (or Downloads) and tap the downloaded SurveyCalc-6.2.2.apk file. If your device asks which app to open it with, choose Package Installer.
3. Allow the install (first time only). The first time you install an app from our site, Android may say something like "For your security, your device isn't allowed to install unknown apps from this source."

   This is a standard one-time setting. Tap Settings on that message, turn on Allow from this source (or Allow installing unknown apps), then tap the back button to return to the installer. You only have to do this once — future updates won't ask again.

4. Install. When you see "Do you want to install this app?", tap Install and wait a few seconds. When you see "App installed", tap Open to launch SurveyCalc.

That's it — the app is installed.

Allow permissions on first launch

The first time you open SurveyCalc, it will ask for a few permissions so its features work. Please allow these when prompted:

• Location — for GNSS/GPS positioning and the on-map location overlay.
• Files / storage access — so you can open and save your survey projects, CSVs, and CAD files.
• Nearby devices (Bluetooth) — only if you use Bluetooth to send or receive files between devices.

If you tap "Don't allow" by mistake, you can turn a permission back on later in your device's Settings → Apps → SurveyCalc → Permissions.

How do I pay and activate via PayMongo?

1. In SurveyCalc, open the subscription / license screen.
2. Enter your Gmail account and select a billing plan: 1 Month (₱1,499), 3 Months (₱4,049), 6 Months (₱7,649), or 1 Year (₱14,999). Each plan covers one device.
3. Tap Subscribe and complete payment through PayMongo.
4. After paying, return to the app and tap Status (or Refresh). Your license will activate once the payment is confirmed — this usually takes a few seconds.
5. When it shows "Saved license is valid", you're ready to go.

Tip: if it still says "waiting for payment confirmation" right after paying, wait a few seconds and tap Status again. Confirmation isn't always instant.

Updating SurveyCalc later

When a new version is available:

1. Download the new version from this page (same as before).
2. Open the downloaded file and tap Install (or Update). Install it over the top — do not uninstall the old version first.

Your license and saved settings carry over automatically. You won't need to pay or activate again.

Note: uninstalling the app may remove the license. If that happens, open the license dialog and tap Restore to restore your license.

Troubleshooting

• "App not installed" — Make sure you allowed installation from this source (step 3 above). If you previously installed a different copy, it may help to open the app once before updating.
• My license didn't activate right after paying — Tap Status or Refresh on the license screen a few seconds after payment. Confirmation can take a short moment.
• I changed to a new device — Your subscription is tied to your device. A new device requires a new license.
• I need help — Chat with us on Facebook Messenger and we'll get you sorted.
