Verdict
The clearest difference is in-app purchases: CDC's Milestone Tracker at none against Pooply Tracker's 3. CDC's Milestone Tracker also leads on ads (none vs shown) and rating (4.9 vs 4.5). Pooply Tracker's advantage is update cadence (weekly vs every 6 months). On price, device support and iOS requirement there is nothing between them.
