# Stock Trainer vs ChartMath

The clearest difference is ads: ChartMath at none against Stock Trainer's shown. ChartMath also leads on rating (5.0 vs 4.5) and monetization model (free vs free with in-app purchases). Stock Trainer's advantage is ratings volume (77 vs 5) and iOS requirement (12.0 vs 15.1). On price, update cadence, in-app purchases and device support there is nothing between them.

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

ChartMath holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Stock Trainer has 77 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 80% of Stock Trainer's written reviews are positive against 100% of ChartMath's.

Stock Trainer ships an update every 10 days, ChartMath weekly. Both last shipped on October 24, 2026.
