Verdict

The call

The clearest difference is rating: Block at 4.1 against Clever Dialer's 3.4. Block also leads on update cadence (every 9 days vs every 4 months). Clever Dialer's advantage is ads (none vs shown) and review sentiment (61% vs 30%). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Clever Dialer sells 3 in-app purchases, starting at $1.99 per month and Block sells 2 in-app purchases, starting at $12.99 per 3 months. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Block holds the better App Store score, 4.1 against 3.4. Both are backed by a comparable volume of ratings — 14 and 25 respectively. Written reviews complicate that: 61% of Clever Dialer's written reviews are positive against 30% of Block's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Clever Dialer ships an update every 4 months, Block every 9 days. Both last shipped on October 24, 2026.
