Verdict
The clearest difference is in-app purchases: Mobile SOS at none against Color Board's 1. Mobile SOS also leads on ads (none vs shown) and iOS requirement (13.0 vs 17.6). Color Board's advantage is update cadence (every 2 months vs every 44 months). On price and device support there is nothing between them.
