About this app

Track decisions as they unfold.

WhyLens is a quiet place to keep the decisions that matter — what you were weighing, what you chose, why you chose it, and what actually happened later.

Most decisions are made in a moment and then forgotten. WhyLens keeps the reasoning, so that when the outcome finally arrives, you can still see the thinking it came from.

Use WhyLens to:
- capture ideas before they are lost
- weigh the paths inside an idea, with points for and against
- turn an idea into a decision and keep the paths not taken
- record what you chose and why
- write down the assumptions it rests on
- add short check-ins while the decision unfolds
- mark when the context has changed
- close a decision when it is reversed, replaced, or let go
- review it later, with distance
- look back at whether another path would have been better
- compare expected and actual outcomes
- see how well your confidence matched real outcomes
- track how your assumptions held up
- notice patterns across your decisions over time
- see the lessons you wrote before, when a similar decision comes up

PRIVATE BY DESIGN
Everything stays on your device. No account is required. Nothing you write is uploaded, analyzed, or sold. Export gives you a PDF or CSV copy of your own data whenever you want one.

WHAT WHYLENS WILL NOT DO
It will not tell you what to choose. It will not score, rank, or recommend your options. It will not predict success. There are no streaks, no badges, and no pressure to open the app every day. Insights come only from what you wrote, and only once there is enough of it to say something honest.

WhyLens is free for up to five active decisions. An optional subscription adds unlimited decisions, insights, export, and finer control over review timing.

For people who make decisions they cannot easily undo — about work, money, health, relationships, or direction — and who would like to remember how they were thinking at the time.

What’s new

Two additions, both about learning from what you already wrote.

• Looking back — after a decision where you weighed several options, note whether another path would have been better. Nothing is scored or judged; the answer is yours, kept with the decision.
• What you've learned — the lessons you write in reviews now collect in one place, and quietly resurface when you start a decision that looks similar.

Also: an optional weekly digest of what is due. Off by default.
