Watch out for fake Petro321 apps
petro321.com is the only place we distribute Petro321. Files advertised elsewhere as a “Petro321 APK”, “mod APK” or “cracked version” are not ours, and look-alike domains with a different spelling are not operated by us. Never enter your Petro321 password or wallet details into an app you did not install from petro321.com.
App questions
Is there a Petro321 APK to download?
+
No. Petro321 installs directly from petro321.com in your browser — there is no APK to sideload. Anything advertised elsewhere as a "Petro321 APK" or "mod APK" is not published by us and may be malware.
Is the Petro321 app on the Play Store or App Store?
+
No. Petro321 is installed from petro321.com using the steps on this page. Once installed, the icon behaves like any other app on your home screen.
Can I use it on a PC or laptop?
+
Yes. Open petro321.com in Chrome or Edge on Windows or macOS and use the install icon in the address bar. You can also just use it in a normal browser tab without installing anything.
Do I need a separate account for the app?
+
No. The app and the website are the same Petro321 account. Sign in with the email and password you registered with; if two-factor is on you'll be asked for the six-digit code as usual.
Does the app cost anything?
+
No. Installing is free and gives you the full account — live output, deposits, withdrawals and your referral team.
