About

Countdown LCD

Features
Read full description

A countdown timer that looks and reads like a real seven-segment display. Big, sharp digits you can read from the back of the room. For speakers, conferences and meetings: start the timer, set your iPhone or iPad on the lectern, and everyone knows how long is left. ON STAGE The screen stays awake while the countdown runs, so it never dims mid-talk. In landscape the digits fill the whole screen. SIX DISPLAYS Four backlit themes glow red, green, blue or amber on true black. Two reflective panels, a handheld-console green and a calculator tan, catch the light like a real LCD. AIM FOR A TIME "Ends at" counts down to a set date and time instead of a length. Beyond 24 hours the display switches to days, hours and minutes, then back to seconds on the last day. AIRPLAY Send the display to an Apple TV or any AirPlay screen: full frame, no controls. Your iPhone stays in charge. NEVER DRIFTS The countdown runs from an absolute end time. Leave the app, lock the phone, relaunch: the time stays exact. A Live Activity keeps it on the Lock Screen and in the Dynamic Island. BUILT FOR THE JOB Duration presets you can edit and reorder. An adjustable extend button for when a session runs over. Siri and Shortcuts to start, pause or add time without touching the screen. NO ACCOUNT, NO TRACKING No sign-up, no analytics, no third-party SDKs, no data collected. It's a timer. One-time purchase, no subscription. For iPhone and iPad.
