Verdict
The clearest difference is rating: 星空交友（原老版树洞） at 4.0 against 33IQ's 2.5. 星空交友（原老版树洞） also leads on ads (none vs shown) and ratings volume (721 vs 12). 33IQ's advantage is review sentiment (53% vs 41%). 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. 33IQ sells 10 one-off in-app purchases and 星空交友（原老版树洞） sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
星空交友（原老版树洞） holds the better App Store score, 4.0 against 2.5. That said, the two scores are not equally well evidenced: 星空交友（原老版树洞） has 721 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 53% of 33IQ's written reviews are positive against 41% of 星空交友（原老版树洞）'s, so the app with the better star average is not the one people write more warmly about.
33IQ ships an update every 5 weeks, 星空交友（原老版树洞） fortnightly. Both last shipped on November 6, 2026.
