Common questions
Which iPhones work with Tappy?
Any iPhone from 2018 or later, updated to iOS 17.6 or newer. That includes iPhone 11 and every newer numbered iPhone, iPhone XS and XR, and iPhone SE (2nd generation or later). To check your version, open Settings, then General, then About.
My card won't scan. What can I try?
Hold the top edge of your iPhone flat against the card and keep still for a moment. Take the card out of a wallet with other cards, and try without a thick or metal case.
Why is my balance different from my Opal account?
Tappy reads what's stored on the card itself and doesn't connect to your online Opal account, so the two can differ for a while. Also, while you're tapped on, Opal holds a fare on your card, so the balance can look lower until you tap off.
Will Tappy work with Opal 2.0?
Transport for NSW is upgrading Opal to a new system, Opal 2.0 (Opal Next Generation), over the next few years. It uses account-based ticketing, where more of your travel information is kept in your online account rather than on the card itself. We don't know yet how this will affect apps that read the card, like Tappy, but we're following the changes. Read Transport for NSW's Opal 2.0 FAQ (opens in a new tab).
Can Tappy top up my card?
No. Tappy only reads your card. For top-up options, see transportnsw.info.
Are the peak times always right?
They're a guide only, and peak times can vary by station. Check transportnsw.info for current fares and service information.
Is Tappy an official Transport for NSW app?
No. Tappy is an independent app made by WarmWolf. It isn't affiliated with, or endorsed by, Transport for NSW.
Is Tappy really free?
Yes. There are no ads and no subscriptions. Tips in Support Tappy are optional and unlock nothing.
How do I remove my saved card?
On the Home screen, tap the bin icon next to Last scanned. Or touch and hold the card, then choose Remove. With VoiceOver, the bin button is called Remove saved card. Deleting Tappy removes it too.
Privacy policy
Last updated 24 October 2026
The short version: Tappy doesn't collect your personal information. There's no account, no ads and no tracking, and your card data stays on your iPhone.
Who we are
Tappy is made by WarmWolf, a registered business name in Australia. In this policy, "we" means WarmWolf. You can reach us at tappy@warmwolf.com.
What Tappy reads from your card
When you scan, Tappy uses your iPhone's NFC reader to read the information stored on your Opal card: the balance, the card number, your latest tap (time, transport mode, and whether you tapped on or off), paid journeys this week, and whether auto top-up is on and the card is blocked.
This happens on your iPhone. It's never sent to us or to anyone else.
What's kept on your iPhone
Tappy keeps only your most recent scan, so you can see it again without rescanning. It stays on your iPhone (and in your iPhone's own backups, if you use them). You can remove it at any time: on the Home screen, tap the bin icon next to Last scanned, or delete Tappy.
The Home Screen widget shows fare times only. It doesn't use your card data.
Fare times and notices
To keep Today up to date, Tappy downloads a small file of peak times, public holidays and notices from our server when you use the app. The request contains nothing about you or your card.
Like any internet request, it shares your IP address with our hosting provider, which may keep it briefly in technical logs to run and protect the service. We don't use it to identify you.
Optional tips
If you leave a tip, Apple handles the payment. We don't receive your name, payment details or Apple Account information. Apple's privacy policy applies to purchases.
