Verdict

The call

Onoff Numbers and FracTELfone both sit at 4.6 stars, but that hides the real split: 100% of FracTELfone's written reviews are positive against 44% of Onoff Numbers's. FracTELfone also leads on in-app purchases (none vs 10). Onoff Numbers's advantage is update cadence (every 2 weeks vs every 7 months) and ratings volume (793 vs 7). On price, rating, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Onoff Numbers holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Onoff Numbers has 793 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 44% of Onoff Numbers's written reviews are positive against 100% of FracTELfone's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Onoff Numbers ships an update every 2 weeks, FracTELfone every 7 months. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
