# Morse Chat vs Rattlegram

The clearest difference is in-app purchases: Rattlegram at none against Morse Chat's 1. Rattlegram also leads on review sentiment (90% vs 74%). Morse Chat's advantage is update cadence (every 2 months vs every 9 months) and ratings volume (486 vs 23). On price, ads and device support there is nothing between them.

Both are free to download. Morse Chat sells 1 one-off in-app purchase. Rattlegram asks for nothing beyond the download.

Morse Chat holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Morse Chat has 486 ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 74% of Morse Chat's written reviews are positive against 90% of Rattlegram's, so the app with the better star average is not the one people write more warmly about.

Morse Chat ships an update every 2 months, Rattlegram every 9 months. The most recent releases landed on September 25, 2026 and September 8, 2026 respectively.
