## What is PreserveRing?

"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
