Verdict
The clearest difference is price: AlgoCards at Free against Algo Demo Pro's $2.99. AlgoCards also leads on update cadence (every 9 days vs every 4 months). Algo Demo Pro's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.6). On in-app purchases and device support there is nothing between them.
