Your habits trade like stocks. Log one and the price rises, miss it and it falls, and every Sunday the market posts earnings on your week. Most habit trackers give you a streak and take it away. This one gives you a price, and it pays most for coming back. HOW IT WORKS 1. List your habits as tickers. $GYM, $ZZZ, $BOOK, or your own. Each one opens at $10. 2. Log them as you go. A logged day lifts the price, a missed day takes 0.5% at the close. 3. Sunday, the market posts earnings. Your week is scored against the guidance you set, ticker by ticker. WHAT MAKES IT DIFFERENT • Comebacks pay double. After two misses, your next session moves the price twice as far. • Three misses in a row halts the ticker until Monday. Not a guilt trip, a trading halt, with a screen that asks what got in the way. • Arm a circuit breaker and a third miss holds the price instead of halting it, so the week keeps trading. • Guidance is a promise you make to yourself, not a target the app picks. Beat it, meet it, or miss it. THE EARNINGS CALL Every week closes with a call. Put your own call on the record before the numbers print, read the print ticker by ticker, take the desk's questions, and set guidance for next week. It plays as a pixel-art trading floor, or as plain type if you prefer. Your answers stay on your device. THE TAPE • One index for your whole fund, weighted the way you set. • A page for every habit: the tape as a line or as candles, a rating from this week's numbers, and your streaks. • An archive of past calls. • A home screen widget with your price, today's move and the tape. • Light and dark, following your system or held either way. SHAREHOLDERS AND EXCHANGES • Send a link and a friend becomes a shareholder. They see your fund and the listings you leave open. Mark a listing private and it never leaves your book. • Open an exchange: a group of funds quoted as one index. The group chat, with a price on it. Joining is free for everyone. • The Street shows how everyone holding a habit is doing, in aggregate only, and only once ten or more people hold it. Opt out in Settings. • Block or report anyone. Blocking is silent. YOUR ACCOUNT • No sign-up to start. Sign in with Apple or Google to keep your fund and carry it to a new phone. • Export your data any time. Delete your account and history from Settings. • No ads, ever.

Plus is optional and adds: • Up to 30 habits • Every week in the archive • Circuit breakers without a monthly cap • Up to 10 exchanges you create • The Lock Screen ticker: a Live Activity on the Lock Screen and in the Dynamic Island, and the medium home screen widget • Your statement as a CSV export • Trading floor palettes: Terminal, Paper and Blue chip, light or dark • An analyst note written by AI each week, only if you allow it Plus is $2.99 a month, or $19.99 a year with a 7-day free trial.
