Verdict

The call

The clearest difference is rating: Buffer at 4.7 against PostBuilder's 4.3. Buffer also leads on ratings volume (34K vs 472) and chart position (#138 vs unranked). PostBuilder's advantage is review sentiment (81% vs 55%) and iOS requirement (13.1 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Buffer sells 11 in-app purchases, starting at $5.99 per month 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.

ReceptionRating · Positive reviews · Number of ratings

Buffer holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Buffer has 34K ratings behind it against 472, so its average is the more settled of the two. Written reviews complicate that: 55% of Buffer'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.

UpkeepUpdate frequency

Buffer ships an update weekly, PostBuilder every 4 days. The most recent releases landed on September 27, 2026 and September 22, 2026 respectively.
