What CropJar does

CropJar is the canning notebook that lives in your apron pocket. Every time you put up a batch — strawberry jam in June, dilly beans in August, a crock of kraut in October — you log it once: the recipe, the method (water bath, pressure canner or fermentation), the jar size, how many jars you got, the processing time you used and the date you sealed them. No more flipping through a grease-stained spiral notebook trying to remember whether the 2024 tomatoes got 35 or 45 minutes. Each batch comes with a built-in processing timer, and CropJar keeps your altitude adjustment notes attached to the recipe so the extra minutes you add at 4,200 feet are written down once and remembered forever. Fermentation batches get day counters instead, with check-in notes for brine level, smell and taste along the way. Everything you seal flows into a pantry shelf view: jars grouped by category with their canned-on dates, oldest first. Open a jar, tap to use it, and your counts stay honest — so February-you knows exactly how many quarts of tomatoes are really left and which shelf year to pull from first. When a batch is gone or cured, record the outcome: how many seals held, what you'd change, and whether it earned a spot in next year's plan.
