# SEO Keyword Research Tool vs SEMrush

The clearest difference is rating: SEO Keyword Research Tool at 3.5 against SEMrush's 2.0. SEMrush's advantage is in-app purchases (none vs 16) and iOS requirement (9.0 vs 15.0). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. SEO Keyword Research Tool sells 15 in-app purchases, starting at $4.99 per 7 days. SEMrush asks for nothing beyond the download.

SEO Keyword Research Tool holds the better App Store score, 3.5 against 2.0. Both are backed by a comparable volume of ratings — 26 and 68 respectively. Written reviews complicate that: 9% of SEO Keyword Research Tool's written reviews are positive against 16% of SEMrush's, so the app with the better star average is not the one people write more warmly about.

SEO Keyword Research Tool ships an update every 3 weeks, SEMrush every 2 weeks. The most recent releases landed on October 29, 2026 and October 22, 2026 respectively.
