Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

MarketSim ships an update every 2 months, Trader Trainer weekly. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
