Verdict
The clearest difference is price: LineRunner at Free against SpaceEars's $3.99. LineRunner also leads on update cadence (every 3 weeks vs every 2 months). SpaceEars's advantage is ratings volume (16 vs 2) and iOS requirement (12.0 vs 15.0). On rating, ads, in-app purchases and device support there is nothing between them.

LineRunner is free to download; SpaceEars costs $3.99 up front. SpaceEars sells 2 in-app purchases, starting at $0.99 per month and LineRunner sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for SpaceEars against 5.0 for LineRunner. That said, the two scores are not equally well evidenced: SpaceEars has 16 ratings behind it against 2, so its average is the more settled of the two.
