Verdict
The clearest difference is price: BigO Algorithms at Free against DataStructureAndAlgorithm's $7.99. BigO Algorithms also leads on update cadence (every 4 days vs every 3 months). DataStructureAndAlgorithm's advantage is in-app purchases (none vs 2) and iOS requirement (16.3 vs 18.6). On ads and device support there is nothing between them.
