Verdict
The clearest difference is review sentiment: Buzz at 100% against Joos's 53%. Buzz also leads on update cadence (every 4 days vs every 3 weeks) and monetization model (ad-supported vs free with in-app purchases). Joos's advantage is rating (4.5 vs 3.7) and ads (none vs shown). On price, in-app purchases and device support 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. Neither carries in-app purchases, so what you see is what you pay.
Joos holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Joos has 26 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 53% of Joos's written reviews are positive against 100% of Buzz's, so the app with the better star average is not the one people write more warmly about.
Joos ships an update every 3 weeks, Buzz every 4 days. The most recent releases landed on September 23, 2026 and September 20, 2026 respectively.
