Verdict

The call

The clearest difference is rating: Rogervoice at 4.8 against Mobyx's 3.7. Rogervoice also leads on ratings volume (1.8K vs 19) and update cadence (every 11 days vs every 2 months). Mobyx's advantage is in-app purchases (none vs 5). On price, review sentiment, ads and monetization model there is nothing between them.

Both are free to download. Rogervoice sells 5 in-app purchases, starting at $2.99 per month. Mobyx asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Rogervoice holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Rogervoice has 1.8K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 73% of Mobyx's written reviews are positive against 67% of Rogervoice's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Mobyx ships an update every 2 months, Rogervoice every 11 days. Both last shipped on October 24, 2026.
