Verdict

The call

The clearest difference is rating: Markov Algorithm at 5.0 against Robot Talk's 3.2. Markov Algorithm also leads on review sentiment (100% vs 60%) and update cadence (every 5 weeks vs every 9 months). Robot Talk's advantage is in-app purchases (none vs 3) and ratings volume (18 vs 2). On price, ads and device support there is nothing between them.
