Nudgeproof

A causal puzzle for iPhone

Spot the shortcut.
Trace what it costs.

Five phases, every trace

Follow the consequence, then repair the route.

Each case follows the same compact investigation loop. Multi-source cases repeat Inspect and Freeze before Rewind. Practice removes the timer without removing the mechanic.

  1. Watch

    See the fictional recording before the trace locks.

  2. Inspect

    Use the Truth Lens to find every recorded source.

  3. Freeze

    Lock each source with its complete consequence bundle.

  4. Rewind

    Return to the declared pre-action state. Ranked time keeps moving.

  5. Repair

    Commit to a route you can defend across Money, Attention, and Privacy.

Built for another run

The boundary is part of the game

Practice stays complete.

Full Game unlocks ranked timers and personal-best competition. It does not unlock hidden cases or a better mechanic.

  • No account, sign-in, cloud sync, or advertising.
  • No product-usage analytics. Only Full Game purchase checks contact the App Store and RevenueCat.
  • No paywalled cases. Every installed case is completely playable in untimed practice.
  • No reward for raw speed. Mastery counts finding the trace, repairing fairly, and reading cleanly.

Plain-language policies

Nudgeproof contains fictional simulations. It does not make purchases, change device settings, or inspect activity outside the game. Case progress and preferences stay on this iPhone.
