Certo AntiSpy vs Moonlock (2026): which should you pick?

Pick Certo AntiSpy if

• Fits if you suspect a stalkerware app on your phone
• Works for people who want a check done on iPhone or Android only

Look elsewhere if

• Pricey if you want Premium Plus with the VPN, at $84.99 a year
• Skip it if you want protection for a computer, as it covers phones only
• Watch out: the deep spyware scan on iPhone needs a computer
• Watch out: Android prices differ from the App Store figures recorded
• Tight if you stay on the free tier, which does less on iPhone than on Android

Pick Moonlock if

• Fits if you have one Mac and want a scanner built only for macOS
• Works for a household of 1, 2 or 5 Macs that wants a one-time purchase option

Look elsewhere if

• Skip it if you also use Windows, iPhone or Android, as there is no app for them
• Watch out: the 7-day trial charges $54 on its own when it ends unless you cancel
• Pricey if you pay monthly, at $13.50 against $54 for the year
• Watch out: the one-time $150 may not include major upgrades and new features, and 2- and 5-Mac prices only show at checkout

Certo AntiSpy

• Mobile only: the product pages cover iPhone (and iPad) and Android, not Windows or Mac.
• The deep spyware scan on iPhone needs a computer.
• The App Store prices are the ones recorded; Google Play shows a range of $4.99 to $49.99 per item, so Android prices differ.

Moonlock

• Mac only: the system requirements list macOS 13 or later, and the site mentions no Windows, iOS or Android app.
• The 7-day trial starts on a yearly plan and charges $54 automatically when it ends unless cancelled.
• Prices for the 2- and 5-device options were not shown without selecting them, so only the 1-device prices are listed here.
• The one-time purchase may not include major upgrades and new features, according to the checkout page.
