■ 평 · 돈 · 근 · 관 — the Korean units the built-in converters leave out. Unit Converter · Baro opens straight onto them, with the everyday metric, imperial, temperature and shoe-size pairs one tap away. Both rows are live: type into either one and the other follows on every keystroke. No equals key, no convert button, no category menu. Cold start to answer is zero taps — the app comes back exactly as you left it, same pair, same digits, same caret. ------------------------------- ● Why these units are hard ------------------------------- • 1 평 = 400/121 m² and 1 자 = 10/33 m have no exact decimal form. Every factor here is an exact fraction, never a rounded decimal, so 84 → m² → 평 comes back as 84, not 83.99999999999999. • 근 means 600 g for meat and 375 g for vegetables, fruit and herbal medicine. Choosing silently makes the answer 60% wrong, so the toggle stays on screen whenever it can change the result. • Shoe sizes are a lookup table, not a ratio. Values outside it say so instead of inventing a number. • Temperature has its own code path, so ℃ and ℉ are never a plain multiplier. Below absolute zero the app says so rather than clamping your input. ------------------------------- ● On the first screen ------------------------------- • A five-slot chip rail — 평 ↔ m², 돈 ↔ g, 근 ↔ g, mm ↔ US, ℃ ↔ ℉ to begin with. A new pair pins itself to the front; tapping a chip already there never reorders it, so muscle memory keeps working. • Two live rows — tap the other one and the caret moves there. No keyboard swap, no mode. • A ⇅ swap that does not drift — it carries the exact value, not the rounded number on screen, so flipping back and forth never moves your digits. • Its own keypad — sixteen keys, painted with the first frame. The system keyboard never appears and the layout never jumps. 00 is there for 1,000 평 and 10,000 g. • Copy — one key puts the result on the clipboard. The app never reads it back. • 평형 for apartments — enter an area and the familiar 평형 label appears with an 전용 / 공급 toggle. Two separate tables, not an invented ratio. ------------------------------- ● The full catalogue, two taps away ------------------------------- 척관법 first — 평 ↔ m², 돈 ↔ g, 냥 ↔ g, 근 ↔ g, 관 ↔ kg, 자 ↔ cm, 치 ↔ cm, 되 ↔ L, 말 ↔ L, 홉 ↔ mL — then area, weight, length, temperature, volume, shoes and speed. Every row previews the answer for the number you already typed, so you see it before choosing. One tap applies the pair, pins it and closes. The list is curated, not exhaustive: a few dozen pairs people actually reach for, instead of a search field. And the info sheet prints every factor in plain text — 1 돈 = 3.75 g, 1 관 = 3.75 kg, 1 평 = 400/121 m², 1 자 = 10/33 m, 1 되 = 1.8039 L, both 근 values, the Mondopoint shoe anchors — so you can check the arithmetic yourself, offline. ------------------------------- ● Private by design, built to be tapped ------------------------------- • Zero network code. Nothing leaves this phone, ever — check it in airplane mode. • No system permissions at all, and no permission prompt anywhere. • No account, no login. Privacy label: Data Not Collected. • Zero analytics, zero telemetry, zero third-party SDKs. No ads, no subscriptions, no in-app purchases. • Every control is at least 64 × 64 pt, body text 24 pt and up, high contrast on AMOLED-friendly black. • Single taps only — no double-taps, no long-press, no swipes, no hidden gestures. • Six languages: English, 한국어, 日本語, Deutsch, Français, العربية (right-to-left included). Deliberately left out: currency and exchange rates (live rates need a network call), cooking cups and spoons (they depend on the ingredient) and 마지기 (too regionally variable to answer honestly). ------------------------------- ● The Baro promise ------------------------------- Unit Converter is part of Baro — lightweight tools that respect your data, your battery, and your time. "The tools you reach for first."

Your calendar manages your schedule. Annidiem remembers the days for you. If you think you're a bit ahead of the curve, this one's for you. Birthdays, anniversaries, exams, trips, moving into a new home, a family reunion — the days that matter deserve better than a crowded calendar. Some are still ahead of you. Some already happened. Either way, they deserve somewhere to stay. Flip the bottom-right corner of a card and it turns over into that day's own record. You don't have to wait for the day itself — write while you're looking forward to it, while you miss it, or the moment it crosses your mind: photos, thoughts, voice memos, short videos, each one stamped with the place and weather of that moment. No folders to create, no "where should this photo go" — it belongs to a day, so it stays with that day. If you remember which day it was, you'll find it again. And when the same day comes round again, every year keeps its own: this year never mixes with last. When a day is no longer in focus, put it away — not throw it out. It leaves your home screen and stops reminding you, while the diary and photos stay, ready to bring back. Life gets simpler. The memories don't have to. - TALK TO THIS DAY — flip a card over for that day's own record; write whenever it comes to you - ARCHIVE — put days that no longer need your attention away, without deleting anything - CARD WALL — big countdown numbers for every day that matters - TICKING MOMENTS — live days/hours/minutes/seconds; past days keep counting up: 1000 days together, 90 days smoke-free, day 300 of the project - WEEK & DAY OF YEAR — which week and day of the year today is, at a glance - PHOTO COVERS — pick a photo for a date and the card becomes its face - ON THIS DAY — the days that happened on today's date in past years surface on their own - DYNAMIC ISLAND — pin any day to your Dynamic Island - WIDGETS — gradient cards, Lock Screen widgets, and a large widget that shows your next five days - ERA OF DAYS — one 3D timeline for all your days: days with photos stand along the road, tap one to fly in - APPLE WATCH SYNC — a glance at your wrist: watch app and watch face complications, updated from your iPhone - TAKE A BREATHER — the screen dims, and the fireworks begin - WORTH SHARING — five share card styles: gradient, minimal, poster, midnight, photo - ANY RHYTHM — daily, weekly, monthly, or an interval you set yourself; paydays and bill days stay in step - FIND ANY DAY — search titles, notes, even "August"; filter to this month, the next 30 days, or what's already past - ASK SIRI — "how many days until New Year?" works, and so do Shortcuts and system search - REMINDERS YOUR WAY — the day itself, or 1/3/7/14/30 days ahead, at a time you choose - TYPE DAYS, GET DATES — enter "100 days" and the date computes itself - FACE ID LOCK — auto-lock in background; some days are yours alone - CALENDAR BRIDGE — import from system Calendar; export .ics/JSON to iCloud Drive - ICLOUD SYNC — sign in to iCloud and every device stays in sync - DATE CALCULATOR — days from birth to today, or today to payday; days between dates, business days, and more - ON-DEVICE AI BLESSINGS — Apple Intelligence writes personalized blessings, fully offline (iPhone 15 Pro or later) One-time purchase · No subscription · No ads · Collects no data — your data stays on your device and in your own private iCloud database, and everything works offline.
