Verdict
The clearest difference is review sentiment: PoolChem Tracker at 100% against INKBIRD's 23%. PoolChem Tracker also leads on rating (4.6 vs 3.7) and update cadence (every 5 days vs fortnightly). INKBIRD's advantage is in-app purchases (none vs 1) and ratings volume (7K vs 8). On price and ads there is nothing between them.
