Set it up, then just wait. Track umeshu, miso, and pickles with a maturing ring, get step reminders, and earn a certificate when a batch is done. No subscription. "When did I start this plum liqueur?" "When am I supposed to turn the miso?" PreserveRing watches the waiting time of your homemade preserves. Snap a photo on the day you start, pick the item — then watch the ring fill toward the best time to enjoy. FEATURES • 30 presets: umeboshi, umeshu (plum liqueur), miso, nukadoko (rice-bran pickling bed), fruit liqueurs, dried persimmons, shio-koji, plus year-round items like pickles, sauerkraut, coffee liqueur and frozen-fruit syrup — every duration and step can be adjusted to match your own recipe • Multi-stage estimates on the ring: earliest, recommended, and peak aging • The presets know each step — turning the miso, sun-drying the plums, removing citrus peel, shaking the syrup jar — and remind you on the right day • "Use-by" reminders for quick pickles, so you enjoy them at their best • Home Screen widget shows days remaining at a glance • Earn an aging certificate when a batch is done — share it or attach it to a gift • Your batches stack up year after year: "2nd year", "3rd year"... • Seasonal crafts calendar: miso in January, plums in June, persimmons in October • Away mode for nukadoko (pause daily reminders while traveling) PRIVATE BY DESIGN • No account. Your data stays on your device and your iCloud • One-time purchase. No subscription • Free for up to 3 active batches; unlock unlimited with "Preserve Cellar" NOTES • Aging periods and step timings are general estimates. Do not consume anything with mold, discoloration, or an off smell • Please follow your local regulations when making fruit liqueurs
