# 最牛计算器 vs Adam's Calc

The clearest difference is in-app purchases: 最牛计算器 at none against Adam's Calc's 1. 最牛计算器 also leads on ads (none vs shown) and ratings volume (15 vs 2). Adam's Calc's advantage is rating (5.0 vs 4.8) and update cadence (every 4 months vs every 10 months). On price and device support there is nothing between them.

Both are free to download. Adam's Calc sells 1 one-off in-app purchase. 最牛计算器 asks for nothing beyond the download.
