Verdict
The clearest difference is rating: PolyChat at 4.9 against Hello Nabu's 4.3. PolyChat also leads on ratings volume (231 vs 7). Hello Nabu's advantage is ads (none vs shown). On price, review sentiment, update cadence 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. PolyChat sells 9 in-app purchases, starting at $12.99 per month and Hello Nabu sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
PolyChat holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: PolyChat has 231 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 96% of PolyChat's written reviews are positive against 100% of Hello Nabu's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on November 7, 2026 and November 9, 2026 respectively.
