Verdict

The call

The clearest difference is rating: RezClock at 2.3 against ASRA Coags's 1.3. RezClock also leads on iOS requirement (10.0 vs 13.4). ASRA Coags's advantage is in-app purchases (none vs 1) and update cadence (every 3 months vs every 35 months). On price, ads, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

RezClock holds the better App Store score, 2.3 against 1.3. That said, the two scores are not equally well evidenced: ASRA Coags has 407 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 10% of ASRA Coags's written reviews are positive against 0% of RezClock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ASRA Coags ships an update every 3 months, RezClock every 35 months. The most recent releases landed on October 14, 2026 and October 2, 2026 respectively.
