Aegis RF-Shield
Turn your phone into a signal-jammer detector.
Detects GPS, GSM & Wi-Fi jamming - the tracker & alarm jammers used in vehicle theft - sounds an alarm, and a live on-screen radar points you toward the source with a proximity beep that speeds up as you close in.
- On-screen threat ring + tactical radar with a direction pointer
- Alarm sound + proximity beep when a jammer is detected
- Works offline after activation - no login inside the app (a quick online check keeps your licence current)
- One phone at a time - keep your key to move it to a new phone later (your old phone then deactivates)
- Android 9 and newer
Try Aegis RF-Shield free for 7 days - no account, no card needed. After the trial the app locks and asks you to pick one of the two options below to keep using it.
Choose how you pay - same app, same features:
- Cancel anytime
- Lowest amount up front
- Stops working if you stop paying
- The software is yours forever
- All future updates included
- Never expires, nothing to cancel
Secure PayPal checkout - no PayPal account needed (card accepted). PayPal settles in USD for South Africa, so you'll see about US$2.99/month or US$29.99 once off on your statement; the rand figure is the guide price and the exact rand amount depends on your bank's rate on the day. The monthly option recurs until you cancel it in PayPal - access runs to the end of the paid month. The once-off option is a single charge with no subscription and nothing to cancel. Either way you get your key + an instant download link. We store your PayPal email to manage your purchase and for support - see our privacy policy.
Already bought Aegis RF-Shield? Monthly or once off - re-download the latest APK with your key:
Privacy - erase my data (POPIA)
Remove the PayPal email and device details we hold for your purchase. Your licence key keeps working - you’ll just re-enter it on the app’s next launch. If your subscription is still active, your PayPal email may be re-collected on the next renewal to manage billing, so cancel in PayPal first if you want it gone for good. Confirm ownership with your key + the PayPal email you paid with. See our privacy policy.
Honest note: a phone can only sense a jammer once you are within its range, and detection accuracy depends on your handset. Aegis is a detection aid for security operators, not a guarantee - treat a clear-sky GPS loss as a prompt to investigate. On the monthly option, cancel anytime in PayPal and your access continues to the end of the month you’ve paid for; on the once-off option there is nothing to cancel - the licence never expires.
