Brewra

A quiet pour-over coffee timer.

What it is

Brewra walks you through pour-over coffee with step-by-step water targets and times. Pick a recipe, set your coffee weight and ratio, and Brewra paces each pour with haptic feedback at every step transition.

Requires iOS 17 or later. Universal (iPhone & iPad).

Five recipes

How it works

  1. Pick a recipe.
  2. Enter your coffee weight (5–80 g) and a ratio (1:14–1:18).
  3. Tap Start. Brewra shows the water to pour and time remaining for each step, with a haptic pulse at each transition.

Quiet by design

No streak counters. No flame icons. No push notifications. No advertising. While brewing, your screen stays on so you can keep pouring.

Privacy first

No login, no account, no cloud. Only your last-used recipe and ratio are stored on device. Nothing is sent to any server. Read the full policy.
