# Sub vs Pet Stop Link

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

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.

Sub ships an update every 5 weeks, Pet Stop Link every 6 weeks. The most recent releases landed on September 20, 2026 and July 17, 2026 respectively.
