# R vs DART Sim Pro

The clearest difference is review sentiment: DART Sim Pro at 67% against R's 0%. DART Sim Pro also leads on ratings volume (6 vs 2). R's advantage is in-app purchases (none vs 2) and update cadence (every 9 days vs every 2 months). On price, ads and device support there is nothing between them.

R holds the better App Store score, 3.0 against 2.7. Both are backed by a comparable volume of ratings — 2 and 6 respectively.
