Verdict
The clearest difference is review sentiment: The Teacher Brain at 100% against Core Math's 33%. The Teacher Brain also leads on rating (4.9 vs 3.4) and update cadence (weekly vs every 23 months). Core Math's advantage is in-app purchases (none vs 1) and iOS requirement (11.0 vs 15.0). On price, ads, monetization model and device support there is nothing between them.
