LCD-84 — Retro Watch & Calc
80s LCD watch & calculator
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Made for iPhone Duo: half-fold it and your watch face stands up top while you tweak it below. 25 retro faces, a real calculator, offline currencies and weather.
Two new faces:
• AGENDA — your next meeting on your wrist: a countdown, the start time and the title, with the two events after it listed underneath. The Digital Crown steps forward through the week ahead and a long-press snaps back to what's next. Choose which calendars it draws from in the iPhone app — hide birthdays or holidays and keep the face to what matters.
• DECIBEL — how loud it is around you, drawn as an LCD bar graph with the current level, today's peak, and a marker at 80 dB, where sustained noise starts to damage hearing. It reads the measurements your watch already records — never the microphone.
Both are part of the one-time LCD-84 Pro unlock, bringing the collection to twenty-five faces.
more Made for iPhone Duo:
• Half-fold it into tabletop and your watch face stands up on the top half while the controls lie flat by your thumb. In Customize, every colour, block and setting you change shows on the face above as you go.
• Unfolded, LCD-84 fills the big inner display; folded, it fits the outer screen.
Also fixed: the Calculator face preview on iPhone now shows its full bottom row, = key included.

1.13.0 Aug 16
A small one: LCD-84 now opens straight to a specific watch face from a link — used by our App Store in-app events, so tapping an event card lands you on the face it's about. Nothing else changed.
1.12.1 Aug 14
A new watch face, a redrawn World Timer, and six new looks for LCD-84 Pro:
• FISHING GEAR — a 23rd face: a solunar fish-activity meter. Watch the fish-activity icons rise and fall through the day, see the next major and minor feeding windows, a moon-phase glyph and the date. Turn the Digital Crown to scrub the shown day up to a year out; long-press snaps back to today. Computed entirely on your watch from the same lunar model as the Marlin dive watch — no signal needed.
• WORLD TIMER, REDRAWN — the equalizer bar graph is retired in favour of an AE-1200-style pixel world map, with a blinking dot marking your selected zone as you cycle it with the Crown.
• SIX NEW PRO THEME PRESETS — Ice, Grape and Mint in a translucent 90s jelly-shell case, plus Titanium, Night Ti and Full Gold in brushed and polished metal. Pick one from the iPhone Customize grid and every colour — case, keys, LCD — updates together.
• Under the hood: settings sync now tolerates future app versions gracefully, so a face or theme this build doesn't recognise yet degrades safely instead of getting stuck.
Nothing else changed.
1.12 Aug 13
A maintenance release.
• If you have been using LCD-84 for a while, the iPhone app will now ask once whether you would like to rate it on the App Store. Once, per update — and never on the watch.
Nothing else changed. The watch app is identical to 1.10.

• CONVERTER, REBUILT (Pro) — the calculator's converter no longer makes you press a key over and over to reach the conversion you want. CONV opens a list: turn the Crown to scroll, tap to pick. Every conversion is listed in both directions, so AUD→USD and USD→AUD are separate entries and there is no direction key to remember.
• TWO MORE CURRENCIES — Australian and New Zealand dollars join the US dollar, euro, yen and pound. Daily European Central Bank rates, cached on the watch so they keep working with no signal.
• SEE WHAT YOU CONVERTED — the screen shows the conversion on two lines now: what you typed above, the result below, each labelled with its own currency or unit. No more wondering which way round a bare number was.
• The converter key reads CONV instead of CV, and while you are converting the 2nd key becomes CUR so reopening the list is a single tap.
• Fixed — typing a digit straight after a conversion added it onto the result instead of starting a fresh number.
• Fixed — changing your home currency could crash the app the next time you opened the converter.

New in 1.9
• VINTAGE face (Pro) — a new face built after the classic black-faceplate digital watch: a black plate running edge to edge inside a themed metal border, a fine gold pinstripe, printed ALARM CHRONO and WATER RESIST markings, and a blue EL BACKLIGHT bar. The catalog is now 22 faces.
• VINTAGE STEEL theme (free) — a silver steel case paired with a new blue-tinted LCD. The blue screen is also selectable on its own, so any face can wear it.
• CROWN VIEWS on Vintage (Pro) — turn the Digital Crown to move the LCD between Time, Dual Zone and Timer, and choose what the two status slots show — day, date, steps, heart rate, weather, sunrise, battery and more.
• SET THE TIMER ON YOUR WRIST — countdown length is no longer an iPhone-only setting. Long-press the LCD, the digits blink, and the Crown sets 1 to 99 minutes; long-press again to lock it in.
• Changed — the Classic face sets its Timer length the same new way. Long-press to set it instead of turning the Crown, which now steps through Timer sub-modes just as it does in every other mode.

New in 1.8
• NUMBER INVADERS (Pro) — the 1980 calculator-game classic as a new game face: digits march across the LCD toward your gun, the Digital Crown aims (0–9 and the "n" mothership), tap fires. Nine speed levels, three lives, beat your HI score. The catalog is now 21 faces.
• CONVERTER (Pro) — a CV key on the calculator's 2nd layer turns it into a converter: km↔mi, cm↔in, kg↔lb, °C↔°F, L↔gal, plus your home currency against USD, EUR, JPY and GBP with daily exchange rates that keep working offline.
• CASE MATERIALS & KEY STYLES (Pro) — dress any face in brushed steel, matte resin or gloss plastic, and pick the calculator's key caps: square rubber, round dome, flat membrane, metal, or two-tone hinged keys.
• WEATHER BLOCKS (free) — High/Low, Rain %, Humidity and Wind join the display blocks, riding the same single keyless weather lookup — and all four join the watch complication's data picker too.
• Fixes — settings changes from the iPhone no longer quietly close the watch app, and calculator keys respond across their full touch area.

New in 1.7
• Five new Pro faces — Square (rugged 80s square digital), Flip Clock (split-flap tiles that fold over as the time changes), Terminal (green-phosphor console — turn the Crown for pages of time, health and weather stats), Moon & Sun (moon phase and a sunrise-to-sunset arc — scrub days ahead with the Crown) and Nixie (glowing tube digits). The catalog is now 20 faces.
• Stopwatch laps — the Classic face's stopwatch now keeps a lap list; scroll the whole history with the Digital Crown.
• Calculator tape — browsing results with the Crown unrolls a multi-line paper-style tape across the LCD.
• Faces gallery — the iPhone Faces tab is now a grid with drag-to-reorder, and your watch swipes follow your order.
1.7 Jul 24
New in 1.6
• Per-face colors — give every watch face its own case, LCD and digit colors. Or turn on "Use one color scheme for all faces" in Customize to theme them all together.
• Four new presets — Field (olive), All-Black (red LCD digits), Two-Tone (silver + gold) and Steel Blue join the preset grid.
• New Pro face — Activity: your Move, Exercise and Stand rings in the LCD-84 look, framing a big retro clock.
• Fixes — the backlight no longer washes out the Stealth (negative) display, and a rare crash when switching to the analog face is fixed.
1.6 Jul 21
New Pro watch complication — put dual time, tide, steps, heart rate or weather
right on your regular watch face, in the LCD-84 look. The Voyager face can now
show up to four complications, or none for a bigger clock. Twin Graph step
counts are more reliable, and there are the usual under-the-hood fixes.
