Verdict

The call

The clearest difference is review sentiment: Pet Stop Link at 55% against Sub's 15%. Pet Stop Link also leads on monetization model (free vs ad-supported). Sub's advantage is rating (4.4 vs 3.9) and ratings volume (778 vs 71). 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 3.9. That said, the two scores are not equally well evidenced: Sub has 778 ratings behind it against 71, so its average is the more settled of the two. Written reviews complicate that: 15% of Sub's written reviews are positive against 55% of Pet Stop Link's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sub ships an update every 5 weeks, Pet Stop Link every 6 weeks. The most recent releases landed on October 21, 2026 and October 15, 2026 respectively.
