# Speech2Math Calculator vs VisualMind

The clearest difference is rating: VisualMind at 4.5 against Speech2Math Calculator's 2.3. VisualMind also leads on update cadence (every 3 weeks vs every 4 months) and ratings volume (3.3K vs 3). Speech2Math Calculator's advantage is iOS requirement (10.0 vs 16.4). On price, ads, in-app purchases and monetization model there is nothing between them.
