Verdict

The call

Contacts Grouping's advantage is rating (4.8 vs 4.6) and iOS requirement (12.0 vs 15.0). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Contacts Grouping holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: SpeedUp Player Pro + has 185 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 42% of Contacts Grouping's written reviews are positive against 65% of SpeedUp Player Pro +'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Contacts Grouping ships an update every 2 months, SpeedUp Player Pro + every 3 months. The most recent releases landed on October 19, 2026 and October 18, 2026 respectively.
