Verdict
The clearest difference is ads: SlovoBox at none against Chatterbox's shown. Chatterbox's advantage is ratings volume (35 vs 1) and iOS requirement (15.0 vs 17.6). On price, rating, 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. Chatterbox sells 3 in-app purchases, starting at $4.99 per month and SlovoBox sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Chatterbox against 5.0 for SlovoBox. That said, the two scores are not equally well evidenced: Chatterbox has 35 ratings behind it against 1, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 30, 2026 and October 16, 2026 respectively.
