Verdict
The clearest difference is rating: Pulsoid at 5.0 against Chatsen's 4.3. Pulsoid also leads on update cadence (fortnightly vs every 2 months). Chatsen's advantage is review sentiment (73% vs 51%) and ratings volume (219 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Pulsoid holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Chatsen has 219 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 51% of Pulsoid's written reviews are positive against 73% of Chatsen's, so the app with the better star average is not the one people write more warmly about.
Pulsoid ships an update fortnightly, Chatsen every 2 months. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
