# SpamBlocker vs Master Cleaner

The clearest difference is review sentiment: Master Cleaner at 71% against SpamBlocker's 14%. Master Cleaner also leads on rating (4.5 vs 2.8) and update cadence (every 10 days vs every 3 months). SpamBlocker's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. SpamBlocker sells 1 one-off in-app purchase and Master Cleaner sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Master Cleaner holds the better App Store score, 4.5 against 2.8. That said, the two scores are not equally well evidenced: Master Cleaner has 3.5K ratings behind it against 6, so its average is the more settled of the two.
