Verdict
The clearest difference is review sentiment: Trailer Shopper at 100% against Science Now's 43%. Trailer Shopper also leads on in-app purchases (none vs 3) and ads (none vs shown). Science Now's advantage is ratings volume (140 vs 1). On price, update cadence and device support there is nothing between them.

Both are free to download. Science Now sells 3 in-app purchases, starting at $0.99 per month. Trailer Shopper asks for nothing beyond the download.
Trailer Shopper holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Science Now has 140 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 43% of Science Now's written reviews are positive against 100% of Trailer Shopper's.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
