Fiz Casino App: What the Mobile Build Really Does
No store download exists. We pinned the browser build to two phones and timed the lobby, the games, the cashier and the data it eats.

There is no Fiz app to download from the App Store or Google Play. Fiz runs as a browser build that pins to your home screen and opens without browser chrome, which is why players describe it as an app. We measured it on a Pixel 7a and an iPhone 13 over 4G and home wifi, in portrait and landscape.

Everything on this page comes from a funded Fiz account opened in March 2026: real deposits, real wagering, four timed cashouts. No paid placements. Page last reviewed .
How to add Fiz to your home screen
- Open the casino in Chrome on Android or Safari on iOS.
- Open the browser menu and choose Add to Home Screen.
- Confirm the name. The icon appears alongside your installed apps.
Three taps, no APK, no sideloading and no permissions granted beyond what the browser already has. That last point matters: any site offering a downloadable Fiz casino app file is not the operator.
What we measured on two handsets
| Test | Pixel 7a, 4G | iPhone 13, wifi |
|---|---|---|
| Lobby interactive | 2.4 seconds | 1.9 seconds |
| Slot launch | 3 to 5 seconds | 2 to 4 seconds |
| Live table launch | 6 seconds | 5 seconds |
| Cashier reachable in | 1 tap from any screen | 1 tap from any screen |
| Data per hour, slots | about 18 MB | about 16 MB |
| Data per hour, live | about 220 MB | about 210 MB |
Nothing here is remarkable and that is the compliment. The build did not reload between games, did not lose a session when we switched apps, and the bottom bar kept search, promotions and the cashier within reach.
Games that actually play well on a phone
Portrait works best on the six-reel Rival titles above. Older Saucify slots render in landscape with smaller buttons, so if you play one-handed on a commute, stick to the newer shelf.
Live tables held a 720p stream on 4G and dropped cleanly rather than stalling when signal weakened. Budget for the data figure above before you settle in for a long session on mobile.
Claiming the bonus from a handset
The cashier is identical on mobile. The offer tick box sits above the deposit amount, and skipping it means no match, exactly as on desktop. Progress on the wagering counter is visible in the account area, which is easier to check on a phone than the desktop layout. The turnover arithmetic is on the Fiz casino bonus page if you want to know what you are signing up for.
The one genuine mobile advantage
Verification is faster from a phone. Photographing ID and a utility bill straight into the upload form took us under two minutes, against a scan-and-transfer routine on desktop.
Withdrawing and signing in on mobile
Payout requests work the same way from the handset, and document uploads come straight from the camera roll. Timings do not change by device, because the delay lives in the approval queue rather than the interface. Our measured payouts are on the Fiz casino withdrawal page. If the pinned icon drops your session, that is normal browser behaviour and the fixes are under Fiz casino login.
Battery, storage and responsible play tools
An hour of slots cost us roughly 11% of battery on the Pixel and 9% on the iPhone, with live dealer roughly double that. Storage use is negligible because nothing installs beyond a cached shell. Deposit limits, session reminders and self exclusion are all present in the mobile account area and took effect immediately when we set them, which is the check most mobile casino builds fail.
What is missing
No push notifications, no offline mode and no native biometric unlock, though the browser password manager covers most of that gap. There is no separate mobile promotion, so nothing is lost by playing on desktop instead. For a browser build the omissions are minor, and we would rather have this than a thin wrapper app asking for contact permissions.
Frequently asked questions
Is there a Fiz casino app in the App Store?
No. Fiz runs as a browser build. You add it to the home screen from the browser menu and it opens without address bar chrome, which is why it looks like an installed app.
Does the mobile build carry the same bonus?
Yes. The cashier and the 400% match behave the same on a handset as on desktop, and the bonus tick box appears in the same place.
How much data does a session use?
Around 18 MB an hour on slots in our measurement, rising to roughly 220 MB an hour on a live dealer table.
Can I withdraw from a phone?
Yes, including document uploads straight from the camera roll, which is the fastest way to clear verification.
