Verdict

The call

The clearest difference is rating: Sub at 4.4 against Z Control's 2.4. Sub also leads on ratings volume (778 vs 67). Z Control's advantage is monetization model (free vs ad-supported) and review sentiment (23% vs 15%). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Sub holds the better App Store score, 4.4 against 2.4. That said, the two scores are not equally well evidenced: Sub has 778 ratings behind it against 67, so its average is the more settled of the two. Written reviews complicate that: 23% of Z Control's written reviews are positive against 15% of Sub's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Z Control ships an update every 6 weeks, Sub every 5 weeks. The most recent releases landed on August 9, 2026 and September 26, 2026 respectively.
