Verdict
The clearest difference is in-app purchases: Simple IP Info at none against Markov Algorithm's 3. Simple IP Info also leads on update cadence (every 3 days vs every 5 weeks). Markov Algorithm's advantage is iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
