Google Play may require a payment method to download free apps in some regions. This is a Google requirement — not a Truepic one. The Truepic Vision app is free to download. If you cannot download the app because you are told a payment method is needed, it could be because you have not previously downloaded an app with your Google account.
How to download without a payment method:
Open Google Play Store on your Android device.
Search for Truepic Vision.
Tap Install.
When prompted for payment, tap Skip to proceed without adding a payment method.
If any cost is shown for downloading the Truepic Vision app, contact Truepic Support before proceeding, as it could indicate your device is compromised.
