Lay out a decision you are stuck on, by criteria and weights
Score your options against your own criteria, then move the weights to see whether the conclusion holds — a decision note with sensitivity analysis built in.
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
- Buy on Gumroad and your license key arrives in the receipt email.
- Swap that key for an unlock code at ektopos.app/redeem, then paste the code into the app.
- You need the internet only the first time (about 10–12 MB). After that it runs with no signal.
What it does
- Score options across several criteria and weight each to get a total
- Show the point where the ranking flips as you shift a weight — how fragile the answer is
- Templates aimed at threshold decisions: accept, switch jobs, walk away
- Keeps the reasoning, so you can later check why you decided as you did
What it does not do
- Runs offline; your options and criteria stay on the device and are not sent anywhere
- No account · one-time purchase · no tracking · no ads
- It does not decide for you. You set the weights; the tool only shows how fragile the result is
When it helps
Job, contract, or direction calls where the facts are in but you still cannot commit
