TapDo

TapDo is an Android app that lets you use NFC cards as intentional triggers for simple digital actions.

Instead of opening multiple apps or navigating through settings, TapDo allows you to associate actions with physical NFC cards — including old or unused debit and credit cards — and trigger them with a single tap.

This app was built to reduce friction and make certain actions more intentional.

What you can do with TapDo:
• Securely save and access card PINs by tapping a card
• Enable or disable silent mode
• Restore normal sound mode
• Trigger simple shortcuts such as flashlight toggle
• Launch supported apps or actions (like calling a number or opening an assistant)

TapDo is designed with a privacy-first approach.
All data is stored locally on your device and is never uploaded to external servers.

Please note:
TapDo is currently in an early testing phase. Some features may be limited, and minor bugs may exist. Feedback from early users helps improve stability and usability before public release.

Requirements:
• Android device with NFC support
• NFC must be enabled on the device

TapDo does not run background tracking, show ads, or collect personal data.

This app is built by an independent developer and is evolving based on real usage and feedback.
