Verdict
The clearest difference is price: RosterSync at Free against Cold Correct's $0.99. RosterSync also leads on rating (5.0 vs 4.5) and update cadence (every 3 days vs every 60 months). Cold Correct's advantage is in-app purchases (none vs 1) and ads (none vs shown). On ratings volume and device support there is nothing between them.
