Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
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.
Buffer ships an update weekly, PostBuilder every 4 days. The most recent releases landed on September 27, 2026 and September 22, 2026 respectively.
