# Hashtag Expert vs PostBuilder

The clearest difference is monetization model: PostBuilder at free with in-app purchases against Hashtag Expert's subscription. PostBuilder also leads on ads (none vs shown) and update cadence (every 4 days vs every 4 weeks). Hashtag Expert's advantage is rating (4.6 vs 4.3) and ratings volume (36K vs 472). On price and in-app purchases there is nothing between them.

Both are free to download. Hashtag Expert sells 12 in-app purchases, starting at $2.99 per 7 days and PostBuilder sells 9 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Hashtag Expert holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Hashtag Expert has 36K ratings behind it against 472, so its average is the more settled of the two. Written reviews complicate that: 72% of Hashtag Expert's written reviews are positive against 81% of PostBuilder's, so the app with the better star average is not the one people write more warmly about.

Hashtag Expert ships an update every 4 weeks, PostBuilder every 4 days. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
