# MarketSim vs Axiom Trading

The clearest difference is monetization model: MarketSim at free with in-app purchases against Axiom Trading's subscription. MarketSim also leads on ratings volume (21K vs 1). Axiom Trading's advantage is ads (none vs shown) and review sentiment (100% vs 67%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. MarketSim sells 2 in-app purchases, starting at $19.99 per year and Axiom Trading sells 3 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

Axiom Trading holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: MarketSim has 21K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 67% of MarketSim's written reviews are positive against 100% of Axiom Trading's.
