Verdict
The clearest difference is rating: PetPage at 4.9 against Fi's 4.6. Fi's advantage is update cadence (weekly vs every 2 weeks) and ratings volume (42K vs 6K). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
PetPage holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Fi has 42K ratings behind it against 6K, so its average is the more settled of the two. Written reviews complicate that: 38% of Fi's written reviews are positive against 33% of PetPage's, so the app with the better star average is not the one people write more warmly about.
Fi ships an update weekly, PetPage every 2 weeks. The most recent releases landed on November 4, 2026 and November 3, 2026 respectively.
