# MarketSim vs Trader Trainer

The clearest difference is rating: MarketSim at 4.6 against Trader Trainer's 4.1. MarketSim also leads on ratings volume (20K vs 486). Trader Trainer's advantage is ads (none vs shown) and update cadence (weekly vs every 2 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. MarketSim sells 1 one-off in-app purchase and Trader Trainer sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

MarketSim holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: MarketSim has 20K ratings behind it against 486, so its average is the more settled of the two. Written reviews complicate that: 66% of MarketSim's written reviews are positive against 67% of Trader Trainer's, so the app with the better star average is not the one people write more warmly about.

MarketSim ships an update every 2 months, Trader Trainer weekly. The most recent releases landed on September 26, 2026 and September 22, 2026 respectively.
