Jeolmi
Read full descriptionHide full description
Jeolmi is a focus timer and to-do list with a small paper seal that copies whatever you write. Type "read chapter 4" and the seal picks up a book. Type "pay rent" and it brings a wallet (empty, it apologizes). Tap start, lock your phone, and the seal is on your Lock Screen and in the Dynamic Island, holding the prop next to your task while the timer runs. Every real 25 minutes of focus inks one grape on today's bunch. Checked-off tasks add grapes too, drawn dotted so you can tell them apart. Fill the day's grape slots and the seal sits up and claps. Once a day. What the seal does Ā· Copies your task with a paper prop, live as you type. There are 32 props to find, and the ones you find stay on your prop shelf. Ā· Stays on your Lock Screen and in the Dynamic Island while you focus. Done, Pause and +5 work without opening the app. Ā· Says one dry line per state. It never coaches and never guilts. Ā· Wears what you give it: outfits, body colors, a four-slot desk. Outfits, desk items and two of the body colors cost Jelly, which you earn by focusing and finishing tasks. Nothing is random. Ā· Goes for a swim once today's grapes are filled and comes back with one line. If you take a few days off, it folds you a paper crane. It never counts the days you missed. Everything below is free Ā· Timer: count up with no cap, a 25-minute countdown, or any length from 5 to 240 minutes. Keeps running if the app is closed Ā· Tasks: tap to check one off, or make it timed and see today's minutes on it. Today, tomorrow, weekday routines, subjects with colors Ā· D-day: finals, SAT, ACT, custom dates, D+ after the day Ā· Widgets: Home Screen and Lock Screen, with today's tasks, grapes and your D-day. Check tasks off right on the widget Ā· Live Activity with the seal and your task, also in the Dynamic Island on iPhones that have one Ā· Stats: a month of grapes, hours per subject, days showed up, lifetime hours Share, if you want A card of today's grapes, a mirror card with your task and the prop, a transparent sticker of your seal for notes apps and Stories, and a three-second clip of the flop or the clap. Nothing is posted anywhere by itself. Quiet by design One note a day at most, in the seal's voice, at a time you pick (8 p.m. unless you change it). A heads-up when a countdown ends. Quiet Mode is one tap. Days showed up are counted, never used against you: two freezes refill on their own, and no message ever says something is at risk. Stays on your phone Everything stays on your phone. There is no sign-up and no email, and your tasks and records never leave the device unless you share a card yourself. The app sends only anonymous usage statistics, never what you write, to help improve it. Your records are part of your iPhone's own backup (iCloud Backup or a computer backup), so restoring or moving to a new iPhone brings them along. In English, Korean and Japanese: it follows your iPhone, and you can switch any time in Settings ā Language. Jeolmi is a spotted seal pup named after injeolmi, the Korean rice cake it resembles. It insists it is a seal, not a sea lion. This matters to it.
