Verdict
The clearest difference is rating: Space Tower at 4.8 against Loop's 4.1. Space Tower also leads on ratings volume (571 vs 8) and iOS requirement (13.0 vs 15.1). Loop's advantage is ads (none vs shown) and update cadence (every 3 days vs every 5 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Space Tower sells 21 one-off in-app purchases and Loop sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Space Tower holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Space Tower has 571 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 40% of Space Tower's written reviews are positive against 67% of Loop's, so the app with the better star average is not the one people write more warmly about.
Space Tower ships an update every 5 weeks, Loop every 3 days. The most recent releases landed on October 23, 2026 and October 12, 2026 respectively.
