TraderJack vs PnL Log: Tracking Your Trades vs Understanding Them
PnL Log is a mobile-first trading journal built around one thing: a visual P&L calendar. You log your daily profit and loss, and the app shows you a color-coded month view of your results. It is clean, fast, and free. A lot of traders use it as a quick way to keep score.
TraderJack is built around a different idea. Keeping score is the starting point, not the destination. This page explains what each tool does, where they genuinely differ, and which one makes sense depending on what you are trying to get out of journaling.
What PnL Log does well
PnL Log's P&L calendar is genuinely well-executed. The month view gives you an immediate visual read of your consistency - green days, red days, patterns across the month. It is mobile-native, which means it is always in your pocket. Logging a day's P&L takes about 30 seconds.
For traders who want a lightweight, visual way to stay accountable to their results, PnL Log is a solid free option. It does not try to do everything. It does the calendar well.
The difference: tracking vs understanding
A P&L calendar tells you what happened. Green on Tuesday, red on Thursday, that kind of week. That information is useful - it gives you a picture of your consistency and a record of your results.
What it does not tell you is why. Why was Thursday red? Was it the same session, the same pair, the same behavior pattern that shows up every week? The calendar shows you the score. It does not explain the game.
TraderJack is designed to get to the why. After your trades are logged, you can ask Jack questions about your own history in plain English. "What is my win rate on GBP/USD on Thursdays?" "Which sessions am I most consistent in?" "Show me the common factors in my last ten losing days." Jack pulls from your logged data and answers directly. You are not navigating a dashboard or building a filter. You are having a conversation with something that knows your trade history.
How each tool logs trades
PnL Log is manual entry at the day level. You open the app, enter your P&L for the day, add a note if you want, and that is the record. Simple and fast.
TraderJack logs at the individual trade level, from screenshots. You take a screenshot of your broker's trade history - MT4, MT5, TradingView, or any platform - drop it to Jack in Telegram, and Jack reads every trade in the image and logs them automatically. You get the full data: instrument, direction, size, price, P&L, timestamps. Not just the day's total - every individual trade.
That trade-level data is what makes the conversation layer possible. If all you have logged is daily totals, you cannot ask "which pairs are dragging my Thursday P&L down." If you have individual trade data, you can.
Platform and access
PnL Log is a mobile app. It is designed for quick daily logging on your phone.
TraderJack lives in Telegram. If you already use Telegram for trading - community groups, signals, news - it is already where you are. Drop a screenshot to Jack at the end of a session, the same way you would send any message.

Which one fits your situation
PnL Log is the right tool if you want a fast, visual way to track your daily P&L and stay accountable to your results. It is free, takes 30 seconds a day, and the calendar view is genuinely useful for seeing your consistency at a glance. If you are early in your trading journey and just want to start building the habit of recording your results, PnL Log removes every possible barrier to doing that.
TraderJack is the right tool if you want to go further. If you have been tracking your results for a while and want to understand them - if you want to ask "why" questions and get answers from your own data - the conversation layer is what changes the tool. Screenshot logging at the trade level gives you the raw material. Jack's ability to work through that data with you in plain English is what turns the data into insight.
The two tools are not really competing for the same trader. PnL Log is a scoreboard. TraderJack is a training partner that has memorized your scoreboard. Both have their place - and for some traders, using both makes sense.
