About
Compare real options without manufacturing a winner. OptionMemo is a private decision journal that preserves what you expected before a choice and keeps later observations separate from the original forecast.
USE THE SAME LENSES FOR EVERY OPTION
Create a memo with two to four options and one to five shared lenses. Write one observable expectation in every option-and-lens cell. There are no weights, winner scores, or opaque recommendations.
CHOOSE AND FREEZE
Select the option you actually chose, add an optional rationale, and set a review date. Freezing creates an immutable snapshot of the title, options, lenses, expectations, chosen option, rationale, and date. A later review cannot rewrite the original forecast.
REVIEW ONLY WHAT BECAME OBSERVABLE
When the review is due, label each chosen-option expectation as Matched, Mixed, Did Not Match, or Not Observable and add optional notes. Unchosen options stay preserved as Counterfactual — not observed. OptionMemo does not invent outcomes for futures you did not live.
KEEP A COMPLETE LOCAL ARCHIVE
Search reviewed and archived memos by title, category, option, or lens. Export every option-and-lens row to CSV at any time. Only the chosen option can contain observation fields; unchosen result fields remain empty.
THE COMPLETE ONE-MEMO LOOP STAYS FREE
The free tier includes one open memo, freezing, the full review flow, complete history and search, CSV export, deletion, privacy information, support, and purchase restore.
ONE OPTIONAL LIFETIME PURCHASE
OptionMemo Lifetime is one USD 19.99 non-consumable purchase with no subscription or trial. It unlocks unlimited open memos, reusable lens sets, descriptive chosen-option counts, and local PDF exports. Core review, history, CSV, restore, deletion, and support remain free.
PRIVATE BY CONSTRUCTION
There is no account, developer server, cloud database, remote AI, advertising, analytics, tracking, or third-party SDK. OptionMemo requests no access to Photos, camera, microphone, contacts, location, HealthKit, notifications, or tracking. Your memos remain in the app container unless you explicitly share an export.
OptionMemo is a recordkeeping tool, not professional advice. It does not score decision quality, recommend an option, verify causation, predict an outcome, or guarantee a result.
