MountainsPre-committed turnaround rules (a Ulysses contract)

Decide your turnaround before you climb, and bind the you of that day

Write your turnaround rules — time, place, weather — before you set out, so the sunk-cost softness at the summit runs into a commitment you already made: a Ulysses contract.

From buying it to using it offline

Purchasing is not open yet. These are the steps for once it is.

  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

  • Fix a rule before departure: “turn back if not at ◯◯ by this time”
  • On the day you only check against it — turning a wavering into a checklist
  • Kept as a record you can use to shape the next outing’s rules

What it does not do

  • Works offline · no account · one-time purchase · no tracking · no ads
  • Not a device that tracks your position and warns you; you check against the rule, it does not enforce
  • It will not retreat for you. It hands the you-of-the-day over to the you-who-planned
