Arbiter

Swipe to a fair tip.

Arbiter turns tipping fatigue into a fast verdict. Start from your baseline percentage, swipe through a rapid service review, and let the app explain why the final tip landed where it did.

Swipe engine

Clear a full service review with one-handed left and right swipes in a few seconds.

Custom manifesto

Edit the rules, add your own dealbreakers, and keep your preferred baseline percentage saved on-device.

Share safely

Post the restaurant name, final tip percent, and your short comment without sharing bill totals, payment info, or server identity.

How It Works

1. Start from your baseline

Set your starting percent once, enter the bill if you want the money math, and launch the verdict.

2. Swipe through service

Swipe right for strong service and left for weak service. Every card moves the tip up or down instantly.

3. Deliver the verdict

Arbiter shows the final percentage, split total, and evidence summary, then lets you share a sanitized public recap.

Privacy-First By Design

No accounts, no sign-in, and no vendor cloud sync.
No analytics SDKs, no ad tracking, and no cross-app profiling.
Restaurant names and short comments stay local unless you explicitly share them.
Shared verdicts are limited to the restaurant name, final percent, optional comment, generated chef graphic, and app name.
Bill totals, tip amounts, payment details, and server identity are not included in the social share message.
