# ChatterBuddy vs KeyWise

The clearest difference is rating: KeyWise at 5.0 against ChatterBuddy's 4.4. KeyWise also leads on monetization model (freemium vs subscription). ChatterBuddy's advantage is review sentiment (100% vs 80%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. ChatterBuddy sells 1 in-app purchase, starting at $2.99 per 7 days and KeyWise sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

KeyWise holds the better App Store score, 5.0 against 4.4. Both are backed by a comparable volume of ratings — 7 and 3 respectively. Written reviews complicate that: 100% of ChatterBuddy's written reviews are positive against 80% of KeyWise's, so the app with the better star average is not the one people write more warmly about.

ChatterBuddy ships an update every 5 days, KeyWise weekly. The most recent releases landed on October 24, 2026 and October 10, 2026 respectively.
