Boiling an egg, timing a presentation, or starting your next Pomodoro – Disco Timer is a universal countdown clock for all sorts of tasks. Setting the timer duration is based on 60-minute circle of traditional analog watches – you just wind it up with a single rotary gesture. Then tap the display to run, pause, or reset the timer. Large, high-contrast representation of the remaining time makes it glanceable from quite a distance. And an option to disable the Auto-Lock can keep the device awake while the timer is running. This comes in very handy when keeping an eye on the progress is as important as the finishing time itself. The face of the timer can be customized by choosing from a variety of color combinations (Premium feature). And for the completion alert – you can select from a dozen great-sounding tones, all of which are crafted exclusively for Codulis apps. Give Disco Timer a try, and let us know what you think!

Know what time it is for everyone you care about, and whether they're awake, at a glance. Meridian puts your cities on a 3D globe you can spin with a finger, and gives each one a split-flap clock that flips like an old airport departures board. When it's night somewhere, that clock turns a cool blue, so you can tell who's asleep before you call, text or book a meeting. SEE THE WORLD, NOT A LIST • A full-screen, interactive 3D globe with your cities pinned by their flags • A moon marks every city where it's night right now • Tap a city in your list and the globe spins to it FLIP CLOCKS THAT MEAN SOMETHING • A split-flap clock for every city, labelled with its time zone (JST, CET, EST…) • Night hours show in blue, so "can I call Mum?" is answered without doing the maths • 12-hour or 24-hour time A TIME ZONE CONVERTER YOU DRAG • Scrub the timeline up to 24 hours either way and watch every clock flip together • Jump to any date to plan a trip, a meeting or a call across time zones • Find the hour that works for London, New York and Tokyo in seconds FIND ANY CITY, ANY WAY • Around 6,300 cities worldwide • Search by city, by country, or by time zone: type PST, CET, IST, JST, GMT and more • Add the same city twice and give each one its own name: "Mum", "Office", "Sam in Sydney" MADE FOR PEOPLE WITH SOMEONE ELSEWHERE • Families and friends spread across countries • Remote teams and international meetings • Travellers, expats and anyone fighting jet lag • Set a home time zone that's different from your phone's PRIVATE BY DESIGN Meridian has no account, no ads, no tracking and no analytics.
