Verdict
The clearest difference is rating: AirsoftCalculator at 3.7 against Arm's 1.0. AirsoftCalculator also leads on review sentiment (70% vs 50%) and ratings volume (18 vs 1). Arm's advantage is in-app purchases (none vs 5) and update cadence (every 6 days vs every 5 months). On price, ads and device support there is nothing between them.
