Verdict
The clearest difference is price: Orbit at Free against On the line's $0.99. Orbit also leads on ratings volume (7.7K vs 140) and review sentiment (94% vs 78%). On the line's advantage is ads (none vs shown) and iOS requirement (9.0 vs 15.0). On rating, in-app purchases, monetization model and device support there is nothing between them.
