You won't find the VZ99 app in Google Play or the App Store. Android phones install an APK from the bookmaker's site. iPhones install it through a configuration profile, which gives a developer outside the App Store extra rights on your phone.
This guide covers every step on both phones, how to check the file and the risks worth reading before you tap install.

Eight lines of specification, enough to tell whether your phone can take the VZ99 app before you tap download.
| Item | Detail | Note |
|---|---|---|
| Android build | VZ99.apk from the bookmaker's site | Allow installs from that source for the browser you download with |
| File size | About 35 MB | Leave 100 MB free for unpacking and installing |
| Install time | About 15 seconds after you tap Install | Keep the screen awake until the icon appears |
| iPhone build | Installed through Safari with a configuration profile | No other browser can complete this step |
| Google Play, App Store | Not published in either store | The file always comes from the bookmaker's app section |
| Fingerprint, Face ID | Biometric sign-in available | Turn it on only on a phone that is yours alone |
| Push notifications | Yes, for odds and promotions | You can switch them off in the app settings |
| Account | Shared with the website | No second registration needed |
The steps below follow the current build. Button names shift a little between Samsung, Xiaomi, Oppo and Vivo handsets.
Pick the tab that matches the phone in your hand.
Open the bookmaker's site
Tap the app button in this guide. The page opens in your current browser.
Choose Android
Find the Android download button at the top of the page or in the apps section. Wait for the file to finish.
Allow this source
The phone asks permission to install apps from outside the store. Grant it to the browser that downloaded the file.
Tap Install
Open the file from Downloads, tap Install and wait a few seconds.
Open it, then revoke the permission
Log in once, go back to settings and switch off installs from outside sources.
People forget that last step. If the permission stays on, a stray file you download later could install without you noticing.

Use Safari
The configuration profile step runs in Safari alone. Open the app button from this guide in that browser.
Choose iOS
Tap the iPhone download button. The phone reports that a website wants to download a configuration profile.
Install the profile
Open Settings, open the downloaded profile, read what it contains, tap Install and enter your passcode.
Trust the developer
Go to Settings › General, find the device management section (its name changes between iOS versions), pick the developer name and tap Trust.
Open the app
The icon appears on your home screen. Log in with your existing account.
Read the risk section below before steps three and four. You can stop at any step and use the website in Safari instead.

An app installed through a configuration profile skips App Store review. Tapping Trust lets your iPhone run software signed by that developer. Depending on the kind of profile, whoever issued it may also get control over some settings on the device.
The profile screen lists everything the profile contains before you agree. Read the whole list instead of skimming: it is the one place iPhone shows you what a profile will touch.
Go to Settings › General, open the device management section, select the profile and tap Remove. The app tied to it stops working. Your balance is kept in the account on the bookmaker's system, not inside the app, so removing the app normally costs you nothing. Before you remove it, screenshot the balance and transaction history so you have something to compare against.
App
Browser
For occasional play, the website is enough and carries no install risk. For regular play on Android, the VZ99 app is handier, as long as the file comes from the right place.
Tick each line. If one fails, bin the file and fetch a new copy through this guide's button.
"App not installed"
A half-finished download, full storage or an older copy with the same name. Clear the file, uninstall the older copy, then fetch it again.
Storage full
Clear photos, videos or apps you rarely use. Leave more room than the file size, since the phone needs extra space to unpack it.
iPhone says the developer is untrusted
You skipped the trust step. Go to Settings › General, open device management and tap Trust.
The app opens and closes
Delete it, restart the phone and install a fresh copy from the download button. Still failing? Use the browser while you wait for support.
Problems after the app opens, such as a rejected password or a locked account, are covered under VZ99 login problems.
No account yet? Create one in the app with the VZ99 registration guide, and enter your name exactly as your bank shows it. Already have one? Log in and check that the balance and bet history match your last visit.
Before the first deposit, read the licence file and the payout flow on the VZ99 safety check page. Game lobbies and payment methods are summed up in our VZ99 casino review.

No. Android installs from an APK on the bookmaker's site, and iPhone installs through a configuration profile in Safari.
The download page says about 35 MB, and it can change between versions. Don't install a file far smaller or larger than that.
It carries risk. The profile skips App Store review, and tapping Trust gives rights to a developer you cannot check. If that is not acceptable, use the website in Safari.
Android warns about every app installed from outside the store. That is the default system message, not a verdict on the file; still, run the file checks on this page before you continue.
Yes. One account covers the app and the website, and the app adds fingerprint or Face ID sign-in. If the two balances differ, stop and check that the app is genuine.
Your money sits in your account on the bookmaker's side, not in the app, so logging in again on the web or in a fresh install normally shows the same balance. Screenshot it before you delete the app.
