Verdict
The clearest difference is review sentiment: Vonix Voice at 100% against Trillian's 57%. Vonix Voice also leads on in-app purchases (none vs 4). Trillian's advantage is rating (4.1 vs 3.5) and update cadence (every 5 days vs every 24 months). On price, ads and iOS requirement 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. Trillian sells 4 in-app purchases, starting at $4.99 per month. Vonix Voice asks for nothing beyond the download.
Trillian holds the better App Store score, 4.1 against 3.5. That said, the two scores are not equally well evidenced: Trillian has 577 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 57% of Trillian's written reviews are positive against 100% of Vonix Voice's, so the app with the better star average is not the one people write more warmly about.
Trillian ships an update every 5 days, Vonix Voice every 24 months. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
