ChartMath is a stock screener with the backtest attached. Every screen ships with its win rate, profit factor, and sample size, frozen at publish and never edited after. Now you can paper trade the setup too, with simulated money and live market prices. HOW THE AI WORKS Our agents read price action, market regime, indicator combinations, and historical patterns, and propose new screens continuously. Each candidate goes through the same backtester we use internally: win rate, profit factor, expectancy, drawdown. Only survivors ship. Nothing is curated by vibes. MULTI-ASSET COVERAGE Now screening: - US equities (NVDA, TSLA, AAPL, AMZN, META, GOOG, MSFT, and 500+ more) - Crypto (BTC, ETH, SOL, and 50+ more) - Futures (ES, NQ, YM, CL, GC) One screen, every asset class. Switch timeframes from 1-minute to monthly without leaving the screen. BACKTESTED, FROZEN, VISIBLE Every screen shows the full backtest: win rate, profit factor, average gain, max drawdown, sample size, last update. The numbers are timestamped and frozen. We never edit a win rate after publishing. PAPER TRADE THE SETUP Every paper trade starts from a screen that already has evidence behind it. The ticket carries an entry, a required stop, and a take-profit target. You choose how much of the paper account to risk, and ChartMath calculates the share count from the distance to your stop. You see the dollar loss at the stop before you place the trade. Portfolio tracks what is open. Stats shows expectancy, profit factor, win rate with sample size, and whether your stops held. One trade is noise. The batch is the verdict. MARKET BREADTH See how many stocks are actually participating before you take a setup. Breadth tracks the percentage of stocks trading above their 20, 50, and 200 period moving averages, with the count and the median distance from each. Above 70 percent is broad strength. A thin reading means a handful of names are holding the market up. Sector rotation shows which sectors are leading and which are rolling over. WHAT YOU GET - 200+ AI-validated screens across stocks, crypto, and futures - Paper trading with a required stop, a target, and risk-based position sizing - Portfolio and stats: expectancy, profit factor, win rate, stop adherence - Market breadth and sector rotation: percent of stocks above the 20, 50, and 200 SMA - Real-time scanning every minute the market is open - Swipe-based discovery: see the chart, see the data, decide in seconds - Smart alerts on your watchlist, deduplicated and throttled - Plain-English reasoning for every setup WHO IT'S FOR - Swing traders with a day job, who need the market watched while they work - Traders moving from gut calls to a written process with risk on every trade - Anyone who wants to test a setup with simulated money before risking real capital - Crypto traders who want backtested setups, not Twitter calls - Futures traders who want clean entry signals on ES, NQ, CL - Anyone who got burned by AI-signal apps with edited win rates WHAT WE DON'T DO Most signal apps guess. They edit win rates after the fact, charge for a coin flip, and bury the data behind a paywall. We got tired of that game. No upsells inside the app. No edited win rates. No 5-star nag screens. No stacked subscriptions. One price, every screener, every backtest. Trade discovery, the way it should work. For educational purposes only. Not financial advice. Paper trading uses simulated money and live prices. Simulated results do not guarantee future performance.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
