DoughLab — the baking recipe notebook for serious bread bakers Great bread is never perfect on the first try. Tweak the formula a little each bake, capture photos and notes, and promote your best round to "main." A precise baking tool for home bakers who care about sourdough and naturally leavened bread. • Baker's percentage formula engine Every ingredient is calculated against flour at 100%. Convert grams ↔ percent instantly, and see hydration (water %) and total dough weight at a glance. Set a target like "1.2 kg total" or "6 baguettes" and the weights scale to match. • Bake plan (schedule) — timeline + start reminders Put your bakes on a timetable. Pick a recipe and the total time fills in from its process steps; a notification tells you when it's time to start. Set weekly repeats for your regular bakes. See your baking day at a glance in day and week views — great for bakers managing a shop's oven schedule, too. • One recipe, many formulas Stack every bake of a recipe. Clone a round you liked, change just one thing, and bake again — then compare photos, ratings and notes side by side. Pin your best formula as the "main" so it shows first. • Ingredient stock that links to recipes Register the amount on hand (g) and expiry for flour, yeast, levain and more. DoughLab flags what's short for a recipe, warns when you're running low against the amount you first bought, deducts what you use automatically, and lets you restock right there. • Build a recipe in 4 steps Name → yield → formula → method. Pick ingredients from a multilingual library with a tap, or type your own. Search and stack steps — mixing, autolyse, fermentation, shaping, baking — and your method writes itself. • Immersive baking mode One process step per screen. Change the batch size and the grams for every step recalculate automatically — easy to follow even with floury hands. • Bake log Track your best loaf with average ratings, total bakes and photos. Make today's loaf better tomorrow. • Dark mode · multilingual · offline An easy-on-the-eyes dark theme for night baking. Korean, English, Spanish and French. Everything is saved on your device and works offline. Search: baking recipe, bread recipe, sourdough, baker's percentage, hydration, dough calculator, home baking, bread journal, ingredient inventory, baking schedule, bake planner, bread timer

The longer you put your phone down, the deeper your life gets. Start the timer, set your phone down, and sea creatures come to your ocean. From exam prep to digital detox, dive with Sumbi. Sumbi is a study focus timer and digital detox app named after the "sumbisori," the whistling breath of Jeju haenyeo, Korea's legendary free-diving women. Start a dive when you want time away from your phone. While your phone rests, your ocean deepens, and sea creatures come to live in it. Who dives with Sumbi - Students who need a study timer for exams and deep focus - Anyone fighting phone addiction or doomscrolling - People who want to cut screen time and rebuild concentration - ADHD brains that need a gentle, visual reason to stay off the phone - Anyone who just wants to watch a calm ocean and breathe What makes Sumbi different 1. One dive = one focus session. Keep your phone down while the timer runs, and the dive succeeds. If you fail, nobody scolds you. 2. Your focus time becomes an ocean. Successful dives bring creatures from shallow water, deep water, even the abyss. 3. Collect and raise your sea creatures. The more you dive, the wider and deeper your ocean grows. 4. Gift creatures to your dive buddies. Focus is deeper together. 5. No ads, no noise. Sumbi never drags you back with notifications. Coming back is your choice. Study timer, pomodoro, or deep work Pick any length with the dial: a short pomodoro-style session or hours of exam prep. Every dive adds to your daily focus record. When haenyeo divers surface, they release a long whistling breath: "hooo-ee." Your day deserves a breath that deep. Have a good dive. Hoo-ee! Contact: sumbi@niceday.io
