Verdict

The call

The clearest difference is in-app purchases: Algo Demo at none against Algorithmics's 3. Algo Demo also leads on iOS requirement (13.0 vs 15.1). Algorithmics's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 4 months). On price and device support there is nothing between them.
