Verdict
The clearest difference is price: Per Watch at Free against Orbitrack's $4.99. Per Watch also leads on update cadence (fortnightly vs every 2 months) and rating (5.0 vs 4.7). Orbitrack's advantage is ratings volume (964 vs 8) and chart position (#44 vs unranked). On review sentiment, ads, in-app purchases and device support 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
Per Watch is free to download; Orbitrack costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Per Watch holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Orbitrack has 964 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 76% of Orbitrack's written reviews are positive against 71% of Per Watch's, so the app with the better star average is not the one people write more warmly about.
Orbitrack ships an update every 2 months, Per Watch fortnightly. The most recent releases landed on October 22, 2026 and October 10, 2026 respectively.
