MacKeeper vs Moonlock (2026): which should you pick?

Pick MacKeeper if

• Fits if you want cleanup tools and a scanner in one Mac app
• Works for one or three Macs on a yearly plan

Look elsewhere if

• Skip it if you use Windows or a phone, as only Mac is covered
• Pricey if you pay monthly at $14.95
• Watch out: the homepage says from $10.95 a month while the pricing page shows lower figures
• Watch out: the refund must be requested within 30 days and is lost after six months of use
• Tight if you stay on free: one week of malware scanning only

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

MacKeeper
