A helpful transportation app for everyone

[JanelleHarper]

Hello folks. Just like the title reveals, I want to ask for helpful transportation apps that everyone should have. Can you give me some recommendations? Thanks in advance for your suggestions.

I know very little about apps but would there be something that would tell the driver of a Trailerbus if boarding passengers had tapped on with their Opal card to avoid fare cheats?
