Verdict
The clearest difference is review sentiment: 12Calc at 96% against MyRepChat's 13%. 12Calc also leads on rating (4.9 vs 2.5) and ratings volume (927 vs 59). MyRepChat's advantage is price (Free vs $8.99) and update cadence (every 3 weeks vs every 5 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
