# SpamBlocker vs Instaclean

SpamBlocker and Instaclean both sit at 2.8 stars, but that hides the real split: 59% of Instaclean's written reviews are positive against 14% of SpamBlocker's. Instaclean also leads on in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 3 months). On price, rating, ads and monetization model there is nothing between them.

Both are free to download. SpamBlocker sells 1 one-off in-app purchase. Instaclean asks for nothing beyond the download.

SpamBlocker holds the better App Store score, 2.8 against 2.6. That said, the two scores are not equally well evidenced: Instaclean has 41 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 14% of SpamBlocker's written reviews are positive against 59% of Instaclean's, so the app with the better star average is not the one people write more warmly about.

SpamBlocker ships an update every 3 months, Instaclean every 3 weeks. Both last shipped on October 23, 2026.
