1. Request the installer
Open the download page and message us. We send the current build and confirm which licence fits your volume.
From requesting access to exporting your first clean list. Follow it in order and the first run works — most setup problems come from skipping the preparation, not from the software.
Do them in this order. Each one assumes the previous is finished and working.
Open the download page and message us. We send the current build and confirm which licence fits your volume.
Install the package we send, launch it, and check the version shown in the title bar matches what we told you.
Scan the QR code for your first slot and wait until it reports Ready before touching anything else.
Load a small prepared file first. One number per line, full international format, duplicates removed.
Save the active and inactive outputs separately. Keep the inactive one permanently as a suppression list.
Only after a clean test run should you add more slots or load a large list.
Do not skip the test file. Running 50–100 numbers you already know the answers for is how you confirm the setup is right — for the price of a hundred checks instead of a hundred thousand.
Windows 10 or 11, 64-bit. There is no macOS or Linux build — on those, use cloud checking in the browser.
The app drives a Chrome session. ChromeDriver updates are handled for you, which removes the most common cause of a filter tool suddenly breaking.
One works. Two to four is the practical sweet spot. Use numbers with real history rather than fresh SIMs.
Sessions drop on unreliable networks. A mid-run disconnect means re-running that batch.
These four cover almost every setup ticket we receive.
Usually Chrome is missing, out of date, or blocked by security software. Update Chrome, allow the app through your firewall, then reconnect the slot.
Almost always a formatting problem, not a real result. Check your numbers have country codes and no leftover trunk prefix.
You are running too hard on one account. Slow the intervals, add slots, or move the job to cloud checking, which uses no account.
Nine times out of ten this is a Chrome update. Restart the app so ChromeDriver re-syncs, then try one slot.
The single biggest factor in whether your first run looks right is the file you feed it. Before importing:
Per-country rules and worked examples are on the country reference page, and the full workflow is in how to filter WhatsApp numbers.
Add slots one at a time. Connect a slot, wait for Ready, confirm it is stable, then add the next. Connecting several at once makes it impossible to tell which one is failing.
Two to four slots suits most teams. Ten is available but only worth it if you are running very large jobs regularly and have accounts with real history behind them.
The multi-account guide covers slot planning and what to do when one disconnects mid-run.
The app works through a logged-in WhatsApp session, so the account doing the checking carries some risk. You can lower it:
None of this removes the risk, because the risk is the account itself. If you cannot afford a restriction, cloud checking uses no account at all.
Licences start at $15 and scale with slot count and term. Tell us your volume and the countries you work with, and we will recommend the smallest option that covers you rather than the largest.
Activation is tied to your machine. If you change hardware, message us and we will move it. Verified legitimate buyers also get a 7-day money-back guarantee if support cannot make the software work as promised — full conditions are in our terms.
Through the official download page. Access is issued per buyer so we can verify licences and give you setup support directly rather than leaving you with an installer and no help.
Install Chrome, connect a single slot and wait for Ready, then import a small test file of numbers you already know the answers for. Confirm the output matches reality before scaling up.
Yes. V16 Pro supports up to 10 slots. Add them one at a time and confirm each reaches Ready before connecting the next.
No. It is a Windows application. On macOS or Linux use cloud checking, which runs in any browser with no install.
Message us with your list size and the countries you work with. We will send the build, your licence recommendation, and walk you through the first run if you want.
