Popularized by the Simpson's season 10 episode, "They Saved Lisa's Brain" and implemented by French Revolutionaries from 1793 to 1795, metric time consists of 10 hours per day and 100 minutes per hour. Mid-day is 5:00 and midnight is 10:00, easier than imperial numbers for orienting your day-to-day activities. With the clock's simple and direct display, you can show your friends a different way to tell time, or set up a display on your desk, with your iPhone or iPad. Metric minutes are a little bit longer than imperial minutes, so be patient when watching the time progress. Because there are 100 minutes in an hour, the time 4:85 is equivalent to 4.85 (decimal); click on the time to convert between colon or a period in the time display. Click the paint brush button to change the colors of the interface. Also, switch back and forth between local metric time and Universal metric time with the globe button. ## Key features - Metric time display - 10 hours per day - 100 minutes per hour - Customizable interface colors - Local and Universal metric time - Decimal time conversion ## Recent user reviews (10 of 13) All indexed reviews: https://appshunter.io/ios/app/the-metric-clock/id1496188857/reviews.md ### 5/5 — Metric time is best time *2025-11-09* Love that this app exists. Wish it had an analog clock display mode. ### 3/5 — Wishing for a widget. *2025-08-12* I installed this clock with the hope it would include a widget. Unfortunately, it does not. I wish it would also explain "Universal Metric Time", because it's certainly not UTC. ### 5/5 — Looking for something like this for YEARS *2024-09-07* Finally, finally…I found a metric clock app that displays the decidays and millidays rather than some .beat time system or other nonsensical numbers. I’m very pleased with this app😊 Green numbers on a black background is my favorite color combination offered by this app. Will gladly continue using. ### 5/5 — Wish this was the real time *2023-11-10, version 1.9* Sometimes, in fact a lot, time calculations are a real pain. I like to fantasise that the revolutionaries got their way and time could be the same as our money and measuring systems ie decimal based. How much easier would this be? Full marks for allowing time to be hours.minutes. ### 5/5 — Time reading *2021-11-14, version 1.9* The time reads minutes past after 50 where it should read minutes to. Yes? ### 4/5 — Metric calendar *2020-12-29* This is a very good and fun app, one suggestion though, would it not be better if it also included the metric calendar instead of the Gregorian calendar? ### 2/5 — While interesting, disappointing. *2020-12-16* The clock in it self isn’t wrong I think? but has no effective features. cannot set up an alarm, no widget feature. has potential for anyone wanting to convert to metric time system but falls short. it’s gimmicky requiring me to leave the app open to see the time (in metric) could have been so much more but apparently just a gag to confuse friends or something? Suggestions for developer: -add an alarm -add a calendar feature or make a calendar app -add widget -if possible change the apple time in settings -stop watch feature -timer (countdown) feature I would love to use this for actual life purposes it’s a shame it’s the only app I hope this gets updated. Not bad, just not useful. ### 5/5 — New world order *2020-06-18* I’m a huge fan of metric everything, including time. Part of my new world order requires the conversion to the metric system, including metric time, and even a metric calendar. I love this app. I was about to develop one myself, but it already exists. Well done!!! ### 4/5 — Good but almost 5 stars if... *2020-06-08* App is great but if there were option of being able to see the metric seconds that would make this 5 star ### 5/5 — Great App! *2020-05-27* I love the simplicity of this app and especially love the colour schemes, you can have understated or high contrast if you need to keep an eye on the time easily. It could only be better if there was a Watch Complication to compliment it :) ## Frequently asked questions about The Metric Clock ### What is metric time on The Metric Clock?
