# Intergalactic Algebra vs C4K

The clearest difference is price: Intergalactic Algebra at Free against C4K's $2.99. Intergalactic Algebra also leads on rating (4.8 vs 4.0) and ratings volume (6 vs 1). C4K's advantage is in-app purchases (none vs 10) and iOS requirement (11.0 vs 13.0). On review sentiment, ads and device support there is nothing between them.

Intergalactic Algebra is free to download; C4K costs $2.99 up front. Intergalactic Algebra sells 10 one-off in-app purchases. C4K asks for nothing beyond the download.

Intergalactic Algebra holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Intergalactic Algebra has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
