Bubbles: Sourdough Starter

Bubbles is a sourdough starter tracker, rescue guide and bake planner in one app. It guides you from day 1 to your first baked loaf, and even has discard recipes so nothing goes to waste!

Keeping a sourdough starter alive is easy until life gets in the way. Bubbles remembers the feedings, warns you before your starter is in trouble, and tells you exactly what to do when something looks wrong.

TRACK FEEDINGS AND NEVER MISS ONE

Set your feeding schedule once and get a reminder when your starter is due
Full feeding history, so you can see how your starter is really doing

IS MY STARTER DEAD? PROBABLY NOT

Rescue alerts warn you before a jar goes too long without a feed
The health check reads your recent history and explains what is actually happening, so you stop guessing
Guided rescue plans for a sluggish, hooch-covered or stalled starter
Straight answers about the strange things a levain does — the smell, the liquid on top, the flat days

A BAKE PLANNER THAT WORKS BACKWARDS
Pick when you want fresh bread out of the oven. Bubbles builds the whole schedule in reverse — feed, mix, folds, bulk ferment, shape, proof, bake — with a reminder for every step. It lines up your starter to peak right at mix time and inserts a feeding if it needs one. Timers keep running when you close the app.

18 TESTED SOURDOUGH RECIPES
From a first country loaf to focaccia, bagels, sandwich bread and pizza dough. Every recipe scales to your tin, warns you if your starter is not ready to bake, and walks you through each step.

BUILT FOR REAL KITCHENS

Rest your starter in the fridge and wake it in time for a weekend bake
Split it, name the offspring, and see your family tree: who came from whom, and who needs a feed
Track discard and get recipe ideas so nothing goes to waste

YOUR DATA STAYS ON YOUR PHONE
Every starter, feeding and bake lives on your device. Nothing is uploaded and nothing is sold. Core tracking works offline. Only ads and account sign-in need internet.
