LCD-84 — Retro Watch & Calc

Now with a live watch complication — put dual time, tide, steps, heart rate or weather on your face in the LCD-84 look. Plus a calculator, 8 retro faces & a UFO shooter.

Remember when your watch could do math?

LCD-84 puts the digital watches of the 80s on your Apple Watch — not as pictures, but as working machines. Type on the calculator. Time your laps. Shoot the UFOs. Every key clicks with a haptic and a genuine piezo chirp, and a tap lights the blue-green electroluminescent glow.

EIGHT FACES • Calculator — an LCD clock over a working numpad. Start typing and it calculates: authentic chain math, 8-digit display, backspace, and a 2nd key with %, √, ± and memory (M+ M− MR MC). Turn the Digital Crown to scroll your calculation history. • Classic — the big-display digital with MODE-cycled sub-modes: Time, lap Stopwatch, Countdown Timer and Dual Time. The stopwatch and timer keep running even when the app is closed. • Analogue — retro hands sweeping over an LCD-colored dial, with two configurable sub-dials and optional hour numerals (arabic, roman, or the mixed bars-and-numerals style). • Ana-Digi — analogue hands plus a small digital window, straight out of 1987. • Minimal — day, date and big digits. You know the one. • LED — the 70s red-LED watch: dark until you tap, then the time glows. • World Timer — dual-zone time with the equalizer bar graph. • UFO Game — the 1980 game watch, faithfully: it's a watch first (big LCD clock, high score), then you tap to play. Steer with the Crown, tap to fire, every shot beeps. The pace quickens as you score.

MAKE IT YOURS The iPhone companion app configures everything: theme presets, case and key colors, LCD styles, digit tint, key-beep sounds, and the display blocks — weather, heart rate, battery, world time, week number, seconds, stopwatch and more. Settings sync to the watch automatically, and a complication on your regular watch face launches LCD-84 with a tap.

LCD-84 PRO — ONE PURCHASE, YOURS FOREVER The free app includes the Calculator and Classic faces. A single unlock adds the other six faces, the DBC Gold and Resin Black theme packs, the Blue EL backlight, the chirp pack and edge-to-edge full-screen dials. No subscription.

PRIVACY No accounts, no ads, no analytics, no tracking. Location is used only to fetch local weather (optional), and heart rate never leaves your watch.
