The short version. The trading journals that are genuinely native iPhone apps are Kyra, TraderSync, TradesViz, TradeReview, UltraTrader, SuperTrader, and Plancana. Kyra is the private, on-device, no-account option; the others are cloud-account apps, most built around broker sync. Three of the most-recommended "journals" — TradeZella, Tradervue, and Edgewonk — are web apps only, not native iOS apps at all.
This distinction matters because the popular lists blur it. Ask a search engine or an AI for "the best iOS trading journal" and it will happily include TradeZella and Tradervue — tools you can *open* on an iPhone in Safari, but which have no app on the App Store. If you specifically want a native iPhone app (offline capture, Face ID, a real app icon, no browser tab), that filter alone cuts the field in half.
Native iPhone app vs "works in the browser"
A native iOS app is downloaded from the App Store and runs on the phone. A web app runs on a company's server and you reach it through a browser; a PWA ("progressive web app") is a web app you can pin to your home screen, which looks app-like but is still a hosted web page. All three can be used on an iPhone — but only the first is a native iPhone app, and only a native app can log a trade with the app closed, offline, in a couple of taps. The table sorts the field on exactly that line.

Where Kyra fits — the private, on-device iPhone option
Kyra is a native iPhone app that keeps your trade history on your device, with optional sync through your own private iCloud, and no account to create — no email, no password, nothing uploaded to a company server (why on-device). Logging is built for the phone: a Quick P&L entry takes a couple of taps, and you can capture the emotion and setup while the trade is still fresh. Instead of a dashboard that totals your numbers, Kyra runs statistical tests on your own history and surfaces a behavior pattern only when the sample supports it, each with its sample size shown (how pattern detection works). Before you plan a trade, the free risk/reward calculator pressure-tests the geometry.
You want a private iPhone journal
You want a real App Store app that logs fast on the phone, keeps your data on-device with no account, and reads your own behavior statistically — win rate by emotion, setup, and time of day, with the sample size attached.
You want auto-sync or a web suite
Kyra does not auto-sync from your broker, has no trade replay, no backtesting suite, no AI chat mentor, and no web app. If any of those is the dealbreaker, a cloud journal below serves you better — and this guide says so plainly.
How to choose
Answer the one question that matters most to you. Do you want your data on your own device with no account? That points to Kyra. Is never typing a trade by hand the dealbreaker? Lead with broker auto-sync — TraderSync, UltraTrader, or SuperTrader on iOS; TradeZella if you'll accept a web app. Do you want an all-in-one web suite with replay and backtesting? That's TradeZella or TradesViz, and you'll be in a browser for the deep features. The best iPhone journal is the one whose trade-offs you actually agree with — the broad field, across web and native, is sorted in the best trading journal apps guide, and the privacy angle goes deeper in the private trading journal guide.
