iPhone
The sourdough journal for iPhone, not just a checklist, but your personal journal for every bake. Free to use, with Premium you get even more insight. No account needed.
You bake. Bloom remembers.
You learn a craft by doing and by remembering what works. Bloom is your personal sourdough journal. Not a checklist app. A journal. One for every bake, every experiment, every loaf that was just a little better than the last.
WHILE YOU BAKE
Step by step, without distraction. Timers for autolyse, bulk and proofing. Notes while you work. Bloom keeps the structure, you keep the feel.
AFTER THE BAKE
The bread is gone. The bake stays. Score your crust, crumb and taste. Bloom analyses what could improve. While you're already thinking about the next loaf.
BETWEEN BAKES
See when your starter is ready. Look back at your bakes over time. Plan your next bake. Bloom is there even when you're not baking.
