InvestingPre-committed investment theses, checked against outcomes

Write down why you are buying before you buy, lock it, then check whether you honored it

A tool for writing down why you are buying, before you buy, and locking it: sign the thesis, the exit conditions, and the intended holding period, and the entry can no longer be edited; when the outcome is in, you mark each condition honored or broken and reconcile it against what you wrote.

US$5, bought once. Payment is handled by Gumroad. JPY pricing is planned for the future Google Play editions.

From buying it to using it offline

  1. Buy on Gumroad and your license key arrives in the receipt email.
  2. Swap that key for an unlock code at ektopos.app/redeem, then paste the code into the app.
  3. You need the internet only the first time (about 10–12 MB). After that it runs with no signal.

What it does

  • Write the thesis, the exit conditions, and the intended holding period, sign the entry, and it can no longer be edited
  • When the outcome is in, mark each condition honored or broken and reconcile the entry — did the buy stand on its thesis, or on a mood?
  • Writing theses, locking them by signature, and recording reviews (honored / broken / the outcome) remain free and unlimited for good, with or without a purchase
  • Nothing you recorded disappears if you do not buy — the reconciliation ledger keeps listing the three most recent reviews, and each review stays readable in its own thesis; rates such as the honor rate are always computed from every record
  • The one-time purchase unlocks depth: reconciliation by rationale tag (honored/broken counts and an honor rate per tag), the full history of the reconciliation ledger, all five rationale-tag templates (two are free), and Markdown export to the clipboard

What it does not do

  • Works offline · no account · one-time purchase · no subscription · no tracking · no ads. What you type — labels, theses, notes — stays on the device and is not sent anywhere
  • No notifications, no streaks, no badges — a tool you open when you need it, not one that comes after you to make you open it
  • A tool for discipline, not investment advice. It does not recommend securities, does not advise on buying or selling, and does not predict prices or performance
  • It does not connect to market data and does not calculate profit or loss — everything it handles is what you typed in, amounts included

When it helps

Anyone who wants to fix in writing, before they buy, why they are buying — and later check whether the buy stood on its thesis or on a mood
