Verdict
The clearest difference is in-app purchases: CDC's Milestone Tracker at none against SayBright's 2. CDC's Milestone Tracker also leads on ads (none vs shown) and ratings volume (10K vs 3). SayBright's advantage is update cadence (every 5 weeks vs every 6 months). On price, rating, device support and iOS requirement there is nothing between them.
