What's New in Crumb

1.8

October 30, 2026

What's new in 1.8: • A whole new Community feed: swipe through full-screen cards with seasonal recipes, baking facts and tips, mixed in with bakes from other bakers. • Bake it yourself: tap any feed recipe to see the ingredients and steps, then add it to your Recipes. Add up to 3 free, or as many as you like with Pro. • Better recipes: add steps, add-ins like seeds or cheese, and amounts in spoons and cups. You can now delete a recipe right from your list. • Bakes know their recipe: link a bake to the recipe you followed and see every loaf you've made from it in one place. • Fixed: a bake you just scored now posts to the community without the "only scored bakes" error.
