Verdict

The call

The clearest difference is review sentiment: OptiTools Mobile at 100% against Google Voice's 14%. OptiTools Mobile also leads on iOS requirement (15.0 vs 26.1). Google Voice's advantage is rating (4.3 vs 3.5) and update cadence (weekly vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Google Voice holds the better App Store score, 4.3 against 3.5. That said, the two scores are not equally well evidenced: Google Voice has 62K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 14% of Google Voice's written reviews are positive against 100% of OptiTools Mobile's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Google Voice ships an update weekly, OptiTools Mobile every 4 months. The most recent releases landed on November 13, 2026 and November 6, 2026 respectively.
