Verdict
The clearest difference is review sentiment: GTP API Gravity Calculator2 at 100% against Yale Access's 41%. GTP API Gravity Calculator2 also leads on ads (none vs shown) and iOS requirement (12.0 vs 17.6.1). Yale Access's advantage is price (Free vs $9.99) and rating (4.9 vs 4.0). On 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
Yale Access is free to download; GTP API Gravity Calculator2 costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Yale Access holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Yale Access has 75K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 41% of Yale Access's written reviews are positive against 100% of GTP API Gravity Calculator2's, so the app with the better star average is not the one people write more warmly about.
Yale Access ships an update fortnightly, GTP API Gravity Calculator2 every 2 months. The most recent releases landed on October 16, 2026 and September 24, 2026 respectively.
