Verdict
The clearest difference is rating: NVIDIA GTC at 4.6 against SPIE Conferences's 3.8. NVIDIA GTC also leads on ratings volume (741 vs 9) and monetization model (free vs ad-supported). SPIE Conferences's advantage is iOS requirement (14.0 vs 16). On price, review sentiment, 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.
NVIDIA GTC holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: NVIDIA GTC has 741 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 25% of SPIE Conferences's written reviews are positive against 21% of NVIDIA GTC's, so the app with the better star average is not the one people write more warmly about.
SPIE Conferences ships an update every 3 weeks, NVIDIA GTC every 9 days. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
