# Senpa.io vs Jurassic Dinosaur Attack

The clearest difference is rating: Jurassic Dinosaur Attack at 4.5 against Senpa.io's 3.9. Jurassic Dinosaur Attack also leads on update cadence (every 8 days vs every 9 months). Senpa.io's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Jurassic Dinosaur Attack holds the better App Store score, 4.5 against 3.9. Both are backed by a comparable volume of ratings — 171 and 117 respectively. Written reviews complicate that: 58% of Senpa.io's written reviews are positive against 50% of Jurassic Dinosaur Attack's, so the app with the better star average is not the one people write more warmly about.

Senpa.io ships an update every 9 months, Jurassic Dinosaur Attack every 8 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
