Verdict

The call

The clearest difference is rating: Google Voice at 4.3 against S1 Timer's 1.8. Google Voice also leads on update cadence (weekly vs every 4 months) and ratings volume (62K vs 19). S1 Timer's advantage is review sentiment (38% vs 14%) and iOS requirement (11.0 vs 18.0). 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 1.8. That said, the two scores are not equally well evidenced: Google Voice has 62K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 14% of Google Voice's written reviews are positive against 38% of S1 Timer'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, S1 Timer every 4 months. The most recent releases landed on October 20, 2026 and October 4, 2026 respectively.
