Mantis is a native iOS trading journal built for serious retail traders who want to stop guessing and start improving.
Instead of maintaining a spreadsheet that you abandon after two weeks, Mantis lets you log trades in seconds — directly from your iPhone. It automatically calculates the metrics that matter: win rate, R-multiple, profit factor, max drawdown, Sharpe ratio, holding time, and more.
Key features:
• Log trades in seconds — entry, exit, instrument, notes
• Automatic metric calculation — no formulas, no manual math
• Performance dashboard — see win rate, R-multiple, and drawdown at a glance
• Trade review — filter by instrument, strategy, or time period to find patterns
• iOS native — works on iPhone and iPad, no web app required
• Free to start — no account needed to try it
Built for: day traders, swing traders, forex traders, crypto traders, options traders, and anyone who wants to trade with more discipline and less guesswork.
