What it does
See the wait.
Get told what's next, right on time.
Not just a plum-liqueur app — a companion for seasonal handiwork. Set it up, then let the ring and reminders take it from here.
30 built-in presets
Umeboshi, umeshu, miso, nukadoko, fruit liqueurs, dried persimmons, shio-koji — plus year-round items like pickles, sauerkraut and coffee liqueur. Pick a photo and a date — every step and milestone falls into place.
Step reminders
Turning the miso, sun-drying the plums, removing citrus peel from a liqueur. The presets know each step and remind you on the right day.
Multi-stage estimates
Earliest to enjoy, recommended peak, a full year of aging. See them all as pins on the ring.
Aging certificate
Earn one when a batch is done, with start and finish dates, days aged, and before/after photos. Perfect for gifting or sharing.
Seasonal crafts calendar
Miso in January, plums in June, persimmons in October. A monthly nudge for what's worth starting next.
Widget
Drop it on your Home Screen and see "days remaining" at a glance.
The step guide paper can't give you
“Is it time
to turn the miso yet?”
The miso turn at day 90, sun-drying umeboshi during doyo (roughly Jul 20–Aug 7), removing citrus peel from a liqueur — the presets know each step and remind you on the right day.
Steps and milestones are marked as pins on the ring, so you always know what's next.
Completion becomes something to keep
“The umeshu's ready.”
Make it a certificate.
Earn an aging certificate when a batch is done — start and finish dates, days aged, before/after photos, and a certificate number, finished with a washi-paper look.
Attach it to a gift, or share it to Instagram Stories. Your batches stack up year after year: "2nd year," "3rd year"...
