# DISCS vs Spacecraft AR

The clearest difference is rating: Spacecraft AR at 3.1 against DISCS's 2.0. Spacecraft AR also leads on ratings volume (25 vs 3). DISCS's advantage is update cadence (every 2 months vs every 7 months) and iOS requirement (8.0 vs 15.0). 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.

Spacecraft AR holds the better App Store score, 3.1 against 2.0. That said, the two scores are not equally well evidenced: Spacecraft AR has 25 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 50% of DISCS's written reviews are positive against 53% of Spacecraft AR's.

DISCS ships an update every 2 months, Spacecraft AR every 7 months. The most recent releases landed on October 1, 2026 and October 20, 2026 respectively.
