Open the app and a market is already running: 50 assets, all of them moving. Majors grind. Meme-tier coins swing double digits before lunch. Every price is generated on your device for training and reflects no live market β that is the point. Read the chart. Candlestick and line views across four time ranges, MA, EMA and Bollinger overlays, a VOL/MACD/KDJ/RSI sub-pane, and a long-press crosshair that reads out any candle you are unsure about. Place the order. An order book ladder, market and limit orders, one-tap position sizing β then a portfolio that keeps holdings, open orders, trade history and allocation while the position runs. Get it wrong. That is what the practice account is for: no stakes, unlimited retries, and a mistake that costs nothing but the lesson inside it. Then work on the part a chart cannot teach. Thirty original lessons across five disciplines, fourteen scenario drills that drop you inside the hard moments β the vertical chart you want to chase, the third trade after two straight losses β and a fifty-term glossary you can bookmark as you go. Practice data stays on your device: no account, no sign-up, no ads, no in-app purchases. Everything here is simulated, and nothing in it is investment advice. Real markets charge tuition for every lesson. This one doesn't.

Verdict
The clearest difference is in-app purchases: ZENTRAX at none against CryptoHODL's 1. CryptoHODL's advantage is device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
